Question on Scatter Plot, among many

I'm plotting time vs a voltage level with a scatter chart as the time the data starts with varies. The problem is the chart always start at 0 so the actual plot is **** on the right side of the plot squish up against the border. I can't see any way to adjust the x axis to the time that I want.

Hi Mark,
I tried plotting minutes, seconds milliseconds (X axis) versus voltage (Y axis).
minutes, seconds milliseconds formatted as Duration > Custom:
It worked, but as you found, I could not change the minimum X value. Also the values on the X axis made no sense to me.
So I converted Durations to minutes. Formula in C2 (and Fill Down):
=DUR2MINUTES(B2)
C becomes Automatic format.
Now plotting C (Minutes, X axis) versus D (Voltage, Y axis)
Possible now to change the minimum value for the X axis:
Depending upon your aim, instead of DUR2MINUTES you could use DUR2SECONDS or DUR2MILLISECONDS
I set up a header column so I don't have to input the label on the chart. I also list Column 1 as the header on the chart.
I am still not sure what is in your Header Column.
Regards,
Ian.

Scatter plot question

I have the new NUMBERS app (3.5.2) on my Mac.
I want to plot X and Y data points. I think this is called a SCATTER PLOT.
But all data points in the graph are one color/ one symbol. See below. For 3 data points this may be fine BUT I have 50 data points.
I want to be able to have different colors for each data point plotted in the graph.
If I create a table of data as per below image, would this solve the issue? If so, what type of graph do I plot?
I have tried lost of variations and even in EXCEL but nothing seems to be graphed.
Thank you.
Michael

This is how charts work. That includes Numbers, Excel and other spreadsheets. A column of values is called a series and all data points for a series will be the same color. I think it will be difficult to tell the variation in colors for 50 different colors and it will take a while to create it. I believe Numbers starts repeating colors after a while (I can't remember how many series before it repeats)
Assuming your first column is your X values, keep that column as a single column like in your first screenshot. Each data point that is currently in your second column will need to be in its own column (but on the same row as before). You may have to "Edit Data References" on the chart and select to plot columns as series (found at the bottom-left of the Numbers window) or it will assume you are plotting "rows as series". And you will have to manually change the colors of nearly all the data points on the chart if you want 50 different colors.

Trendline in Scatter plot

Hi,
I have a couple question on Power View 2010
1. I want to know if I can plot regression Trendlines(Linear/polynomial/power) on scatter plot?
2. Navigation between pages- Is it possible to navigate between report pages in Power View 2010 by passing parameters from the first page to the next page?
3. I have a report that has 3 pages. I want to create 2 pages in SSRS 2012 and one in Power View 2010. Is it possible to navigate between these applications and also pass parameters in the URL?
Thanks in advance.

The reason why it hangs is because you have 2 event structures inside a loop. You should only have one event structure in a loop. This is documented in the LabVIEW Help. With 2 event structures one of them will block the other.
Your code is also about 3 times larger than it needs to be:
To create the array of names for the dropdowns you only need to autoindex a for-loop from the 2D array of data and use the Format Into String function. You don't actually need to use the values - you only need to autoindex the for-loop.
Using Delete From Array and Reshape Array just to pull out a row is simply silly (not to mention a Rube Goldberg). That's what Index Array is for.
In the Cursor Move event case you only need one function: Index Array. The point index is already available to you from the event case's data.
Half of the code really belongs outside of the while loop since none of that data ever changes, so what's the point of regenerating it each time?
Instead of using 2 Index Array functions just to get the list of names, wire a True to the Read From Spreadsheet File's transpose? input and use the first row output.
I've attached a simplified version of your VI.

How to select all (dots) in a scatter plot matrix?

I have a scatter plot matrix, and I'm manually changing the color of each trend line, which probably isn't the best way but it's an easy but time consuming way to do it. I can't feasibly change the color/stroke of every single scatter plot dot in every single scatter plot graph of the matrix. I'm trying various Select --> Same or Select --> All but it keeps trying to change everything, from the line to the border to the dots. I am not sure if I can group the dots and select all or something. Is there a way to select all of the dots and just the dots?

I feel like I should have posted screenshots of my graphs for all of my questions. In any event I've been manually changing the colors of the lines and the dots (see the few graphs on the left, I highlighted the inside of the graph and changed the dots and the line and then just manually changed the line back)

How do I connect the scatter plot points in the newest numbers?

I just made a scatter plot for biology and I was wondering how I connect the points with lines

It sounds like all of your wireless clients (computers & printer) are having issues with the overall signal quality of your Wi-Fi network.
I suggest that you check out the following Apple Support article on the sources of Wi-Fi interference and try to identify & eliminate as many as possible to improve your wireless network.
You may also find the following Macworld article helpful on troubleshooting for Wi-Fi interference. Although this article is specific to the AirPort routers, it can equally apply to any manufacturers' product.

Scatter plot line width

First off, I'm using the trial version of iWork '09. So I want to eventually put a chart into keynote to present to my colleagues, however, putting the chart up on a projector requires me to have a thicker plot line. So if I use a scatter plot, my axis' turn out great, but I cannot adjust the line's width. I don't want symbols, I just want a line connecting the points. If I use the line chart instead of the scatter, the x-axis displays "Untitled 1, Untitled 2" as the labels. I can't change them to the corresponding numbers which is annoying. I can change everything else fine: axis line width, font size, etc. Its just eh connecting line I'm having trouble with

Actually, found a roundabout way to do this. Have to use line chart and in the x-axis label, you have to insert your formula for what cells you want such as Table 1 :: B212:B912 and just set the category counter to only include one label every so many counts. Kind of a pain, but works. However, can't have only the few tickmarks (should be 5 labels and corresponding 5 tickmarks in my case, but I have 5 labels and 700 tickmarks), all are shown instead. It tacks all of the labels individually, but you can choose which ones are shown, but cannot remove tickmarks... Any ideas?

Scatter Plot Problem!!

Hello everyone,
I am quite new at Labview and I have a question regarding plotting 2d-array in a scatter plot.
I would like to plot my data as a scatter plot, which I have done with the Waveform graph, and now I would like to find out the area with the highest density in the scatter plot
and mark the area with a circle...is it possible in Labview to realize this?? I would be very thankful for every tips!
Thank You
Best Regards
Yun

Yes it is possible. You said you are using a waveform graph, wouldn't an XY graph be a better choice? I don't know the data you are getting so a waveform graph might be the right tool here.
In either case you'll need to define a length of X that you want to find the denses amount of points. So say X=1 so then you will find all the points between 0 and 1 and count them, then 0.1 to 1.1 and count them, then 0.2 to 1.2 for the length of X on your graph. Doing this in a For loop will make it easy, and then your output will be an array of counts for each section. Find the maximum using the Array Max & Min function.
Then you can highlight the graph using property nodes. You can use a cursor, or annotation, or a custom picture. The easiest would probably be an Annotation and in the Example finder there is one called "Graph Annotations" that find the minimum, maximum, and average values for a graph and put an overlay on the graph.

Scatter Plot Option

In many cases a scatter plot is necessary to evaluate measured data. A direct option to select a scatter plot chart in the 2D-axes Dialogbox
would improve the usability of Diadem VIEW a lot.

Hi ntur,
It's not as convenient as a scatter plot option but you can at least workaround by configuring markers on the curve in a color of your choice while at the same time setting the curve color to none. Maybe you can make use of some self-defined standard layouts so you don't need to configure the curve / marker parameters each time.

How do to put table of numbers into a scatter plot

I put all the numbers in the table but cannot put them into the scatter plot chart, how do I do this?

Hi talmariexo1,
A Scatter Plot works best if X and Y values are in Body Cells (not Headers).
A Table with one Header Column and one Header Row:
Column A is a Header Column (just an identifier) and does not feature in the Scatter Plot.
Select Columns B and C, then insert your Scatter Plot.
Use Format Panel > Axis to adjust the X and Y steps.
Click on the plot to see Edit Data References.
Column B is grey in this view, but is not a Header Column. Confusing
With Edit Datas References, there are more options at the bottom left of the Numbers Window
But that is another question

Ian.

Axis scale for scatter plots

I'm trying to create a specialized scatter plot, which functions similar to Excel's scatter plot. I'm having problems determining what the min and max values should be for the axes. I would like the program to determine from the input data what the initial min and max values should be on the x- and y-axis, the user can adjust later.
So, I don't want the program to just look at the maximum value imported and round up. For instance, data = {523.7, 514.4, 271.8, 128.5}. The max value is 523.7, round up to 524. Instead, I would like to program to make 600 the largest value on the axis, because that makes it nice round number for the user to view the dataset.
Then, I thought it really depends on the range of the data. For instance, data = {523.4, 523.8, 523.2, 522.8, 523.9}. Here, the range is very small, so it doesn't make sense to have 600 the largest value on the scale. The largest value should be 524 or 525, and the small value on the axis scale should be 521 or 522.
Has anyone else ever worked with this problem, or have a good solution? I would really appreciate it, I've spend way too many days working on this.
Thank you,
Joe

This is off the top of my head and based on a slight variation of your data.
data: 52.34, 52.38, 52.32, 52.28, 52.39
min=52.28 max=52.39 range=0.11
Looking at the range we see it is "on the order of" 0.1. Ie, it is closer to the next lower power of 10 (0.1) than it is to the next higher one (1.0). So we round min down to the next lowest multiple of 0.1 (52.2) and round max up (52.4). 52.2 and 52.4 can serve as the nice numbers.
The range is just a little bigger than a power of 10, so it might be a good idea to check what happens when it's a little less.
data: 135 226 141 143 etc
min=135 max=226 range=91
range is on the order of 100, and the nice numbers are 100 and 300.
As a variation on this strategy if we always find the power of 10 below the range (10 in the second example) we get a tighter fit but the numbers are slightly less nice - 130 and 220.
(I'm pretty sure I've seen - and used! - some java software from the Internet somewhere to find the best scale for axes, so it might pay to look around)
Had to edit my second example and, while I was waiting, found what I have used for this sort of thing: http://geosoft.no/software/index.html (The NiceNumbers class - it finds numbers along a range suitable for major and minor "ticks" but, if memory serves me correctly it extends the range so that the ends are nice too.)

Add point to scatter plot each time a button is pressed

Hi folks,
Apologies if this has been answered elsewhere, I am new to LabVIEW and trying to get an experiment up-and-running quickly!
I was wondering if anybody would have general pointers or code examples on how to create a 2D scatter plot, to which a data point is added each time a button is pressed.
I am measuring a gauge pressure and a force (from a load cell). I would like the scatter plot to add another data point each time I press a button, so that a history of my datapoints is shown. It would also be quite nice is this plot could then be exported as a .jpg using another button, but this is not critical.
A seperate button would also be available to clear the scatter plot.
My current thinking is that this can be done by 'adding to an array', - presumably the chart would refresh each time an element was added to the array, but I am struggling a little bit with how to do this.
If anybody has any suggestions, I would be very grateful for them.
Many thanks,
Euan

Hi Euan,
If you want to have your data shown in real time (and I'm assuming you do) then you'll need to use a Waveform Chart. The chart is able to update itself each time a value is written to it.
The event structure is your friend here: you can write a case to update the chart each time a button is pressed. You can also create cases for the other situations you mentioned (clear chart, export jpg etc.)
If you don't care about the chart updating in real time then you can use your idea of updating an array and then use a Waveform Graph to plot the datapoints at the end of your program.
Take a look at the LabVIEW Basics course and the Examples for info on how to implement the event structure. If you run into any problems just post your VI and we'll see if we can't help you fix them.

How do you make a horizontal average line in a scatter plot?

In any version of Numbers, is there a way to make a horizontal average trendline? Not a "moving average", but one line that is the average that goes through the data points on a scatter plot.

hit a few roadblocks.
I tried:
1. using the crop tool to make the canvas bigger with a transparent background.
2. Used lasso tool over people in group shot (total of 5) and saved the selection
3. Tried content aware scale to raise the image, but it keeps stretching out the people.
Any thoughts on what else I could try?
Rather than trying to stretch it taller, try to squeeze it horizontally. There are methods for telling it what to protect in the image if it gets touchy.
Another possibility is to use Content Aware Fill to make up part at the top and bottom, without any stretching.

Why won't my data appear on my scatter plot graph in numbers?

I'm making a scatter plot graph and I'm dealing with very small numbers on my x-axis, such as 0.0004 and 0.184 on my y-axis. Every time I plot the scatter plot graph, nothing appears on the graph. Can anyone please help me? Thanks.

Highlighting a single data point in a scatter plot - Numbers'09

Is there a way to highlight a single data point on a scatter plot in Numbers'09 (or point to it using a line from each respective coordinate on the x & y axis).
I don't think it matters but the data point i am looking to highlight is the [highest y value/2]... and of course its respective x coordinate once you plug the y value into the equation ( y = f(x) ) and solve for x.

Here is my own tip :
As you see, I use two sets of values.
In the second one I define only the yValue of the data point which must be "highlighted".

Swap X and Y in a Scatter Plot

Seems like this should have a simple answer. I have a table of data, and I'd like to generate a scatter plot of two columns. The plot comes out fine, but I want to "swap" the X and Y axis in the resulting chart.
Is there a simple way to do this? I can't find anything in the chart popup-menu, the inspector, or the application menus.
Cheers
Mike

Michael,
This is a user to user forum, and I'll admit that I don't have a great grip on Numbers Charts, so I may be missing something myself. However, I don't know of an easy way to swap the axes either. What I would do is to create an auxiliary column that repeats the X data in a column just to the right of the Y data. Then I would create a new chart that plots the second and third columns, effectively reversing the axes. The third column can be hidden. Of course you could also just reverse your x and y columns before plotting, but that might be more disruptive to your overall table organization.
Jerry
Update:
I believe that, after some experimentation, I have a better method for you. Highlight the X Range only and create a Scatter Chart. The Chart will be blank since you have not yet supplied a Y range. Then highlight your Y range and drag it to the blank chart. A new Y series will be inserted.
Hope this works for you.
Jerry
