Keynote non-linear scale in line graph

I'm trying to teach kids how to do line graphs and it doesn't help that Keynote treats the horizontal axis like it's a bar graph... even when you want a line graph. It takes the data points and spaces them evenly which can give you a non-linear scale. This is one of the classic mistakes kids make. Grapher can do it correctly but that's one more step.
Any way to make it behave properly?

iMac G4 800, PowerBook G4 12, loads of older ones. Mac OS X (10.4.5) The SE/30 is the king of compacts.

Keynote's graphing capabilities are relatively rudimentary, especially with regards to more technical needs. As far as I know, Keynote always treats X-axis labels categorically (it doesn't understand numeric values), and thus will always evenly space the datapoints.

Semiconductor strain and non linear scales

Dear,
it's not completely clear to me if it's possible to read semiconductor strain gauges with NI hardware?
Do I need special hardware or do I use a normal bridge circuit analog input card (eg NI 9237)?
An added problem with semiconductor strain gauges is the need for linearization of the output because the
basic resistance versus strain characteristic is nonlinear. Is this possible in LabView?
As far as I know, I can only create linear scales in Ni Max?
Thanks in advance,
Ronny Comyn

Yes you can read strain gauges.
No, you dont need special hardware, but it makes things alot easier as signal levels are already adapted.
There's a Convert Strain Gauge Reading which you can read the help text about, depending on the bridge type it'll use different (some are non linear) conversions.

Is it possible to simulate large-scale non-linear systems using the Simulation Toolkit?

Hi,
I am new to LabVIEW, having used Matlab/simulink for a few years. I am trying to simulate a relatively complex non-linear vehicle model. In Matlab/Simulink I would use an m-file to describe the system equations (i.e. x1_dot=..., x2_dot=..., etc.). Is there a similar method in LabVIEW? I have got a simple simulation running using the 'eval formula node', a very ungainly method of substituting variables, and an integrator in a 'simulation node'. It takes about an hour to run a simulation that takes 3 seconds in Matlab. I just need to know if it is realistic to do large-scale simulations in LabVIEW, or if it was not designed for that and I should persuede the management to go
back to Matlab!!!
If it is possible, where can I find help on the subject? I have spent a long time looking on the web and come up with very little.
Many thanks in advance,
Paul.

If these are simple differential equations, easiest would be a for loop with a bunch of shift registers, one for each x1, x2, etc. containing the current values.
In your case, you would calculate all the derivatives from the instantaneous values inside the loop, then add them to each value before feeding them to their respective shift register again.
The attached very simple example shows how to generate an exponential decay function using the formula dx/dt= kx (and k is negative). The shift register in initialized with the starting condition x=1.

Creating multiple Line Graph having common values..

Hi...
I've created one application process for creating Multiple Line Graph.
And i've integreted two tables in this graph, where values may be common for both the tables. In this case, for common values, instead of getting overlapped I'm getting scattered graph(its totally abnormal). Please help me if you 've any idea about this issue.....?
Please go through the App Process and the output of the SQL query.
In output of the query, in the NAME column "Feb-2010" is common.

2D Line Graph Question

I have a 2D line graph that I built. At some points in the graph where the lines intersect the number values displayed on the graph get bunched up and it is hard to read. Is there a way to fix that? This is APEX 3.2 on Oracle 10.2.0.4 database. Thanks

You basically have only a couple of options here:
First, turn off the labels and possibly turn them into Hints. They wouldn't show on the chart, but when the user held over the data point, a tool tip would appear showing them the valuable.
Second, adjust elements of the chart. What you are really looking at here is that your data set is causing this specific issue and not the charting engine or anything like that. You could try to manually change the axis max and min to get more spacing, or you could adjust the height of the chart to get more spacing, but this may not be a viable option. You could have one set of labels above the plotted line and another set of labels below the plotted line that way the values do not overlap with anything. However, from a conceptual standpoint, it will be difficult to determine in code which line should have values above and which should have values below. When your data set changes, you may end up with labels in the wrong place if you hard code where they are at.
The current XML reference can be found at: http://www.anychart.com/products/anychart/docs/xmlReference/index.html however, that is for anychart 5. I'm looking for the link to the earlier versions...
You can use this to create custom xml where you can adjust the position of the labels.
Finally, you do not want expand the height of the chart between two points on the Y axis. That would change the structure of the chart and the visual properties of the chart and the shape of the data would be askew. You cannot do this for good reason. You can though use a logrithmic scale. In most cases though, this is not a practical solution. Data sets need to have very specific characteristics in order to be able to merit a logrithmic scale. Most queries require a simple linear scale.

Help needed in plotting Line Graph!!!!!!!!!Pls help!!

Hi, i need help in plotting a simple line graph showing the x&y axis and has to plot 3 different lines in the same graph.I have written a program and i need to implement this graph in it.Is there any tutorial for plotting line graphs,i mean steps included.
Please help!

You describe your need, but not where it originates from.
Is it a programming assignment? If so, I hope this is not your chosen major, as you will fail because you are a non-resourceful plagarist.
Do you need to simply graph some data? Use an existing package. There are free ones somewhere.
What do you mean "i have written a program and i need to implement this graph in it"? If you wrote the program, wouldn't you be done?
Enjoy programming

Multiple symbols for line graph in illustrator

I can't figure out how to change the default square data points in a line graph. When I try to got to Object>Graph>Marker it is greyed out. When I click on a circle symbol and then try to go to Object>Graph>Design, it is greyed out. I am so frustrated trying to do the simplest things in this program. The online tutorials on how to make graphs do not seem to explain the simplest of tasks, only the difficult. Thanks for any help!

Skeptic,
Yes, it's cumbesome, but it's described in Online Help (at least in CS3 and prior):
Draw whatever you want to use for the marker. (It can be a Symbol; doesn't matter.)
Draw a rectangle and send it behind the marker artwork. For a marker on a line chart, the size of the rectangle relative to the marker art defines the scale.So the rectangle can be smaller than the artwork to make the artwork larger, as shown above. The rectangle can be unstroked, unfilled so it doesn't show.
Select both the artwork and the rectangle. Group. Leave it selected.
Object>Graph>Design. In the dialog, click New Design. Click OK.
Black pointer: Select the graph. Object>Graph>Marker. In the dialog, select the Design you just created. Or...
White pointer: AltClick a single marker in the Graph. AltClick it again to "select up" (Illustrator's upside-down selection scheme) to the parent group. AltClick again to include the legend marker. Object>Graph>Marker. In the dialog, select the Design. This way, you can assign different markers to the various lines in the line graph if you want.

Represent NULL point in Line Graph.

Hi;
      I am using Simple series to supply data to Graph type Line. I have a requirement to represent null data point in Line graph, where marker point for the NULL data point shouldn't be present, instead a straight line should come in between the valid points. Currently if the Data value is null, marker point is coming to 0.
How can i solve this problem using Simple Series?
I am using NW7.0; SP 9

ClickListener in ADF Line graph

Hello,
Is it possible to get the x-axis and y-axis values (i.e.coordinates) of the line graph if user clicks in a line area between points (not the point itself)?
I can get the x-axis and y-axis values if I click on point in a line as follows:
    public void graphClickListener(ClickEvent clickEvent)
        ComponentHandle handle = clickEvent.getComponentHandle();
        if (handle instanceof DataComponentHandle)
            DataComponentHandle dhandle = (DataComponentHandle)handle;
            Object val = dhandle.getValue(DataComponentHandle.UNFORMATTED_VALUE);
            Date timeVal = null;
           Attributes[] seriesInfo = dhandle.getSeriesAttributes();
            if (seriesInfo != null && seriesInfo.length > 0)
                Object seriesName = seriesInfo[0].getValue(Attributes.LABEL_VALUE);
                   Attributes[] groupInfo = dhandle.getGroupAttributes();
                    if (groupInfo != null && groupInfo.length > 0)
                        Object timeObj = groupInfo[0].getValue(Attributes.LABEL_VALUE);
                        if (timeObj != null)
                            timeVal = new Date(((Date)timeObj).getTime());
//However when I click on a line area between the points (not the point itself) then I can get only the series name information, not the x-axis and y axis value:
        else if (handle instanceof SeriesComponentHandle)
            // Get the series attributes
            Attributes[] seriesInfo = ((SeriesComponentHandle)handle).getSeriesAttributes();
            String data = "";
            if (seriesInfo != null)
                for (Attributes attrs : seriesInfo)
                    data += "\nSeries value: " + attrs.getValue(Attributes.LABEL_VALUE);
                    data += "\nSeries name: " + attrs.getValue(Attributes.LABEL_ATTRIBUTE);
                    data += "\nSeries value id: " + attrs.getValue(Attributes.ID_VALUE);
                    data += "\nSeries name id: " + attrs.getValue(Attributes.ID_ATTRIBUTE);
            System.out.println(data);

af:graph

I use af:graph instead of af:lineGraph because the tooltip needs some special customization which af:lineGraph doesn't support.
Just for the sake of the question, I converted the graph to af:lineGraph and I set clickListener in dvt:shapeAttributes as well. It didn't make any difference.
When I click in a line area outside of a point the clickListener gets invoked, however it is not useful since I cannot obtain x and y coordinates.
It goes in the else if section of the code i provided on top of this page. I.e. else if (handle instanceof SeriesComponentHandle) {............}.
My question remains un-answered yet.
Thank you,

Exporting from a 2D line graph with .jpeg extension

Is there any way to export from an ordinary 2D line graph with .jpeg extension so that with using this image i will improve my result of exporting excel.
e.g. i have found and example and added a button as you will see when you run this code.I will click this button and it will export this line graph with extension .jpeg so that i will see it as an ordinary image at my home directory.
Thanks for any helpful comment

How do I make a line graph that shows temperature readings taken on specific dates?

I need to make a chart of my wife's temperatures taken via ovulation thermometer. All I need is a line graph that shows the temperatures on the y axis and the dates the measurements were taken on the x axis.
What is the easiest way to do this? Please explain in detail as I have almost no knowledge regarding Numbers. Thanks.

You can construct a Line graph or a Scatter graph to display this.
The two are similar, but require the data to be set up differently.
A Line graph is a Category graph.
Each 'date' is a text value that names a category. The categories are equally spaced along the category axis. Measurements taken on day 1, day 2 and day 4 would be equally spaced with respect to the category axis.
Each temperature reading is a numerical value, and is represented on the graph by the distance it is placed from (and usually above) the category axis.
A Scatter graph has two value axes.
Each Date is a Date and Time value. The position of these values depends on the value itself. Measurements taken on February 1, February 2 and February 4 wound not be equally spaced. Along the Date axis, the space between the second and third dates would be twice as wide as that between the first and second cates.
Each temperature reading is a numerical value, and is represented on the graph in the same manner as in the Line graph.
Here's an example of each, using the same data set.
For the Line graph (left), the Category labels (dates) are placed in a Header column, and the temperatures in a non-header column,
For the Scatter graph, both the dates and the temperatures are in non-header columns. The Chart Inspector was used to Connect the data points with straight line segments, and the weight of these lines (and size of the data point markers) was increased to more closely match the weights and sizes in the Line graph.
Data on the graphs is not intended to have any similarity to temperatures measured for your purposes.
The construct the line graph:
Set up the data and labels as described.
Select the cells containing the data (column B in my case).
Click the Chart button and choose the Line Chart.
To construct the scatter chart:
Set up the data as described.
Select the cells containing the date and temperature data (columns A and B for mine)
Click the Chart button, and select the Scatter Chart button (third from the bottom),
In the Chart inspector, click the Series button, then set the Connection Points menu to Straight. Change the Data Point size yo 15.
Click anywhere on the line to select it, then in the Stroke section of the Format bar, set the line weight to 4 points.
Click on the box containing the dates (under the chart), then click the ruler icon in the Inspector to show the metrics inspector. Use the Rotate control to set the angle for the dates to about 75°.
Click on the label for this axis (Dates) and drag it to a position below the date labels.

Numbers Line Graph is more annoying than Miley Cyrus

Hello and thanks for taking time to read and answer my question. So I have a science fair project coming up and numbers is being very annoying. My experiment is testing the affect of temperature on the effectiveness of magnets. My table looks like this:
Magnet 1
Magnet 2
Magnet 3
Magnet 4
Magnet 5
Average
74 Degrees
40g
42g
50g
27g
38g
39.4
200 Degrees
28g
25g
35g
46g
38g
34.4
250 Degrees
62g
39g
10g
53g
29g
38.6
300 Degrees
34g
19g
36g
23g
41g
30.6
350 Degrees
26g
21g
17g
36g
37g
27.4
All I want to do is make a simple line graph that will show the correlation (or lack of one) However, when I try to make it into a graph, I keep either getting no lines at all or only the line for the average. Why is this? What am I doing wrong? Help is greatly appreciated.
Thanks so much,
Colton
I'm using numbers 3.1 by the way.

Hi Colton,
"I keep either getting no lines at all or only the line for the average. Why is this? "
It's because the column labeled Average is the only one containing numbers. Appending the g or " Degrees" forces Numbers to regard the values in the other columns as Text, which has no numerical value, and can't be graphed.
With the text stripped from those numerical values you can produce either of these two graphs. See the notes below regrding the major differences.
Scatter chart with connected points
Line chart
Cosmetically, the line graph appears with thicker lines connecting the data points, and with all symbols set to open circles. I thickened the connecting lines on the scatter chart to make them more visible, and made the Average line about 40% thicker than the others. No changes were made to the lines on the line chart.
The legend for both (Magnet 1, Magnet 2, etc.) appears as a horizontal line (or lines) of text. Selecting the box, then dragging either handle toward the other forces the labels into a vertical stack, which can then be moved to a visually better position.
The main functional difference between the two types is in the purpose of the X axis.
In the scatter chart, both X and Y axes are Value axes—the position of each data point is determined vertically by its Y value and horizontally by its X value.
The Line chart is a Category chart. Category charts have one Value axis (here the Y axis) and one Category axis (here the X axis). Categories are equally spaced along the Category axis, and the data points' vertical position(in this example) is determined by the Y value of the point.
In your case, the difference can be seen in the (horizontal) distance between the first two samples in each series compared to the (horizontal) distance between other ajacent pairs in the same series. In the Line chart, these distances are all the same. In the Scatter chart the first pair (74° and 200°) are more widely separated than the others (each 50° higher than the temperature before it).
In cases where you are trying to show a relationship (or lack of relationship) between two sets of values (speed vs braking distance, temperature vs volume, etc.) a scatter chart usually gives a better representation.
Practical note: Values must be placed in non-Header rows and columns. Labels, including Category labels, must be placed in Header Rows or Header columns to be picked up by the chart. The formatting of the pasted data in your initial post indicates the temperatures are in a Header column. The column labels are (and should be) in a Header row.
Good luck with your project!
Regards,
Barry
PS: You might want to check the meanings of "affect" and "effect" before commiting yourself to either on your display and in your report.
PPS to Yellowbox: HI Ian. Looks like you got started earlier and/or wrote faster thn I did! Something odd happened in the example in your first post. The category labels have been offset one cata set to the right, and there's no 350.

3D Line Graph.vi not displaying line connecting data points.

I'm having trouble getting 3D Line Graph.vi to display the line connecting my data points. I'm collecting latitude, longitude, and depth data from a binary file, loading this data into arrays with a while loop, and sending those arrays to 3D Line Graph.vi. When I tried doing it with arrays created by random number generators, the line is displayed, but when I use it with my actual data, no lines are displayed. I can only see where the data points are when rotating the 3D graph. Any ideas on this would be appreciated.
Thanks,
Morgan

Plot Depth.PNG ‏61 KB

Karunya,
Thanks for the info on the 3-D Curve VI. I tried it and it works. I think I was able to find the problem with 3D Line Graph.vi. It has something to do with plotting very close points away from the origin and scaling the axes to view the line. I have attached an example of where the vi breaks down. In this example, you can see that part of the line is drawn, but when you rotate the graph, you can see that the line is not drawn through all of the points. If you change the scale of the axes, then you eventually get the line to go through all of the points, but then the graph is not very "readable" at that point. It's when you try to zoom in really close to the plotted points.
Thanks!
Morgan

Magic Moves not always Magic (non-linear slide orders)

Magic Moves opens the possibility of non-linear slide orders with animated transitions. Previously in keynote (KN '08), as far as I could ascertain, this was impossible. Now a slide with several hyper-linked objects can enjoy an animation of the on screen objects to there new positions, where-ever they may be on the on the linked slides.
Unfortunately, as in some other things Keynote, it seems flakey. While it works most of the time for some reason, even when duplicating the linking slide and repositioning the very same objects, the Move is delayed and instantaneous: decidedly not Magic!
The joy of being able to finally make the fully interactive Keynote presentation that will slide objects the right amount automatically according to there destination slide seems possible. The great thing is I don't have to construct all the different moves linking 26 different pages to each other via various routes (8 links on each page, which happened to be 8x26 possible linking routes = 208 move builds: too much for prescriptive build/move animations).
But if I can't get it too work 100% I can't really show my client. Any know issues with this Magic Move stuff?
I can replicate problem but not predict when it won't work or decode what is triggering the problem. Searching forum only revealed comment the Magic Move is work in progress. Note I am not scaling any objects. Can upload if it helps. Part of the original Presentation with a linear narrative can be seen at:
http://www.vimeo.com/3018559
Essentially I am endeavouring to make all the images 'clickable' so the film strip glides (against the preset order) to become the centre project. Also like to add a left and right button. All this can be theoretically done with invisible rect's with hyperlinks and Magic moves on each slide.
Thanks for reading though all this – hope it's clearer than mud.

Thanks for the response, Kyn.
As it happens writing that long explanation, I thought I'd look from another angle and returned to the file – finding the answer straight away.
Conclusion:
Hyperlinks never use Magic Move transition, even if it is selected transition for the slide. I was getting hoodwinked by the fact that when I had forward and back arrows with hyperlinks to other slides, those slides were before and after the current slide. So they were Magic Moving with a mouse click on the Hyperlink, but only when forward one slide or backward one slide. Any other linking distance failed to Magic Move.
I've already made the feature request but *please second it*, this would be a very powerful feature. Think Non-Linear Presentations and Info Kiosks with seamless transitions. And interaction is an area Powerpoint has decided edge on Keynote so it can and needs to be closed! (PP is such a trial of an interface after KN).

Multiple series on anychart line graph?

I want to set up an anychart line graph from a query which returns a result set something like:
PART DATE QTY
abc 01/01 10
abc 02/01 20
abc 03/01 10
cde 05/01 10
cde 06/01 20
So, in the above I want a series for part abc and part cde. I know I can add another series but that has two problems:
1) The number of distict parts can vary - there might be 2, or might be 20 depending on the parameters used.
2) Adding a new series means duplicating pretty much the same query manu times (with a restriction on part number) - this is very inefficient!
Is it possible to add multiple series "programatically"?

Ah, I never saw the number 10 anywhere.
You don't need to process the NaN with mathscript. It is sufficient to add the NaN to the data going to the graph terminal. Even if mathscript gets an NaN, you can probably test how it is handled.
What does the mathscript node actually do? If it is just doing some scaling, it probably will not matter, but if it would do e.g. a linear regression, it would probably give unexpected results.
