Spacing of x axis points on the graph

how do I set the X axis values to be spaced correctly reletative to each value...currently if i have a values of "10,15,40,80,200" they appear equally spaced..not spaced relative to numerical difference

Can you provide any specific details regarding the kind of graph you are using? Are the values you listed:
"10,15,40,80,200"
X values?
I suspect you want to use a "Scatter" chart and you are not. You can create a scatter chart having nothing selected in a sheet, then select "Scatter" from the Charts menu in the tool bar:
You can then add you own data to the X and Y columns. For more help on using Numbers in general I suggest downloading the free Numbers Users' Guide:

Anchor point in the Graph Editor and where are the Tips

Hello All,
What is the purpose of an anchor point in the Graph Editor when you have "Show Transform Box when multiple keyframes are Selected" engaged. The pointer automatically turns into a PanBehind tool. I moved it inside, outside, on the line and it doesn't seem to have any inpact on the scaling of the transform box. Not only that, it pops back to the center when you switch from "Edit Speed Graph" and "Edit Value Graph"
I haven't used the graph editor much, if ever and was also curious to know what/where are the graph tool tips. I haven't seen any difference when Show Graph Tool Tips is selected.
Thanks in advance

OK, I see the Tool Tips are displayed when you hover over a keyframe or the path that is made.

Line Graph repeats the starting data point at the end also

Hi,
We have a Line Graph as below. This graph is used to show the Salary changes of a person, over time.
But this graph shows an additional non existing data point. Basically it shows the starting data point once again at the end of the other data points.
The model VO for this graph, does not contain this additional data point record. But the graph repeats the starting data point at the end also.
In the screen-shot you can see that, the graph has three data points. But the table has only two. The first data point in the graph is repeated as the last data point.
Is this a Bug..?
Or an issue with the usage of the DVT tags?
The code is given below.
Please advice.
12 <dvt:graph id="lineGraph1" value="#{bindings.SalaryHistory.graphModel}"

If I understand your question, this from the Pages online help may give the answer:
To mark line, area, and scatter charts with data point symbols:
Select the entire chart. You can also select the chart series (the line or area shape) that you want to mark with data point symbols.
Click Inspector in the toolbar, and then click the Chart Inspector button.
Click Series (except for scatter charts).
Choose a symbol from the Data Point Symbol pop-up menu.
Choose one of the following options from the Symbol Fill pop-up menu:
To fill the symbol with the same color as its outline, choose Use Stroke Color.
To fill the symbol with a solid color, choose Color Fill, click the Fill color well, and pick a color.
To fill the symbol with a gradient, choose Gradient Fill and use the gradient controls to set the colors and change the angle of the gradient.
To fill the symbol with an image, choose Image Fill and select the image you want. You can also resize the image by choosing an option from the pop-up menu above the Choose button.
To fill the symbol with a tinted image, choose Tinted Image Fill and select the image you want. Click the color well to the right of the Choose button to change the tint color. You can also resize the image by choosing an option from the pop-up menu above the Choose button.

Is it possible to pick a point in a graph and drag/move it to another position using the mouse?

I have an array which contains sample points.
I would like to be able to pick exactly one of those points in the graph (using the mouse) and move it to another position.
Thanks
Thomas

Hi,
It's better to make just one cursor (in case you have an array of let say
200 points), and make it snap to the nearest point. With the event structure
you can read out if the user has clicked in the graph, read out the cursor,
and when the mouse button is released, change the point to the new location.
Regards,
Wiebe.

How to mark points on a graph

Hi All,
I want to write a program which plots data on a surface graph then
allows the user to click on the graph and "mark" points on the plot. The
program should change the color of the "marked" points on the graph.
Based on the sample code provided by "Ben" here
(http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=144155#M144155)...
I wrote the attached code which uses "event structure" and cursors to do
the job. I used cursor to read the X,Y,Z position of the clicked point on
the plot and store them in arrays. These arrays then were feed into a
new plot added to the graph using CWPlots3D.Add() method. However, my
code does not draw the second plot (which would show marked points in
green) nor it does not get the marked points coordination correctly. I
appreciate your help to correct the code.
Thank you,

Hi Trin,
I have altered your VI a little bit to get the marked points in an array. You will realize that the mouse up event is requested in a parallel loop, that's because this event doesn't get triggered ifyou drag a cursor.
All you have to do now is to make a graph from the array and create new cursors. But leave Cursor 1 always as the last one and save the past values to new cursors. But maybe you don't need to set a cursor on each marked point.
Kind regards,
Kleisi

Add axis label to a graph in word report

Hi,
Is there a way to add an axis label for the graph in a word report? Thanks!

I would guess that there is, but it would be a word automation function.

Points on a graph

Hi,
I am unsure how to do this. I would like for the points on the graph to have values next to them rather than having to move the cursor over these points to get the value at that point.
Any help is much appreciated.
thanks

Amit,
Go into the Chart Designer - select the Series and check the check box for Show Labels.

How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?, How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?

How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?, How do I create a graph with two different y-axis variables with the same x-axis (therefor having two curves)?

Hi Libby,
Select all three columns of data. All three must be 'regular' columns, not Header columns, and the X values must be in the leftmost column.
Click the Charts button and choose the Scatter chart.
The resulting chart will initially show only the first and second columns of data, and the selection will have been reduced to show this.
Click the gear icon at the top left of the selection and choose Share X Values.
You should see a result similar to this:
Notes:
The values on my sample table contain a random element, so they have changed from thhe first image to the second.
The chart is as created by Numbers, with two edits:
Data points have been connected with curves, using the Chart nspector.
The curves were selected and their stroke increased to 2pts, using the stroke formating button in the format bar.

Problems with Tick Configuration on the x-axis in an XY graph

I have set up an XY graph in LabView 2012. The plot area is 1000x750. The x range min is -15. x range max is 15. y range min is -20. y range max is 20. The x and y range increments are 1. The x and y range minor increments are 0.2. The x range start is -14.
When I run the vi the graph comes up in the proper size. The minor grid lines for both the x and y ranges are there at every 0.2 units. The major grid lines are correct for the y scale at every 1 unit. The x scale has a major grid lines at -14 and 14, but in between the major grid lines are at -12, -10, -8, -6 ,-4, -2, 0, 2, 4, 6, 8, 10, and 12. This is incorrect. I expect to see them for every 1 unit as they are on the y scale.
I have change the x range start to -15 keeping all other properties the same. When I do this the major grid lines on the x scale are at -13, -11, -9, -7, -5, -3, -1, 1, 3, 5, 7, 9, 11, 13. Again every 2 units.
I have tried changing the width of the graph along with many of the other properties. Nothing has worked.
Why is this happening? Why does the y scale set up properly but the x scale does not?
I have attached a screenshot of the property node.
Any help is appreciated.

Two things to try:
Use a smaller font for the X-axis.
Change the display format.

A vertical axis needs much less space for a tick than a horizontal axis, so that's expected. We really need to see a simplified version of your actual VI (delete everything except the graph and the property nodes).

Setting the Minimum and Maximum Y Axis Points

Hi,
I have an Application where I need to plot the charts using Time-Scatter Graph .
I am using 2 Y-Axis.
But I am unable to dynamically set the Minimum and Maximum y-axis points through code.
Currently I have set the Minimum and Maximum points for the Y Axis in BG (Business Graphics) Design Time.
Please suggest if we can set the Min & Max values through code as it is very cumbersome to manually set the Min and Max Values for say around 400 odd charts.
We are unable to set the Chart Title too dynamically.
Thanking in advance,
Poojith

Setting the title font and axis labels in a graph created with the Report Generation Toolkit

I'm using the LabVIEW Report Generation Toolkit for Microsoft Office to generate Excel worksheets containing plots. Unfortunately, the default font size used in the plots is huge (see attached worksheet). I was able to use Excel Set Graph Font.vi to reduce the size of the axis labels, but there does not appear to be a function to do this to the title and legend. In addition, there does not appear to be a function to set the axis text labels. Before I write my own, has NI released additional functions to perform these tasks?
Thanks for your help,

Test1_-_embedded_graph's_title_and_legend_font_is_huge.xls ‏14 KB

Hello Zeidan
The graph title and legend font sizes can be changed by accessing a low level VI (Excel_Insert_Chart.vi) that is part of the excelsub.llb that is located at (C:\Program Files\National Instruments\LabVIEW 8.2\vi.lib\addons\_office). This VI is called dynamically from within the Excel Insert Graph.vi and it uses VI server technology to access the Excel exposed properties. Attached to this post is an image of the block diagram of this VI after I have modified it to set the font sizes of the title and legend to 15. The circles in the image represent what I had to add to accomplish this.

Problem with the number format in the graph axis with Report Generation Toolkit.

Hi!
I'm trying to use the Report Generation Toolkit to plot some graphs in Excel.
My first problem is that I don't know how to configure the number format in the Excel Set Graph Font.vi so that my numbers are correctly displayed in the graph's axis. The only given option is general (0,0) but this is not enough for me, my numbers can get really small so I need engineering notation or fraccional format.
Second: I also insert a table with the graph source data, but the numbers are not correctly displayed either: for example:
0,75 is shown as:
0,750000
but 1,25 is shown as:
1!250!000
My guess is I am making to much or wrong string to number conversions or Excel is getting it wrong but I can't find my way...
Can someone help me with this?
Thanks,
Isabel

Here is my VI, it's just a trial so it can look messy...
Thanks,
Isabel

Crystal Reports - Charts - Restricting the data points on the X-axis

Hi,
Is there a way to restrict the number of points to display on the x-axis of a crystal chart keeping the number of data points the same.
For example, if the chart plots date vs value points and the data for the chart is from 1980 to 2009. This means the data points on the x-axis appear very close to each other.
I need a way to show the chart with all data from 1980 to 2009 but limited x-axis labels. Is there a way to configure the number of labels to show on the x-axis.
Thanks!

Thanks for the answer.
"Right click on one of the x axis labels and select Group (X) Axis Options...
On the Layout tab there is an option to Skip Group Labels, check this and enter in the number of labels you want to skip". Is there a way to do this from a .NET client or via a formula field in Crystal itself. The data points is going to be dynamic, hence the requirement is to dynamically configure the "number of labels" to be skipped.
Thanks.

How can you rotate the labels on the category axis of a graph in Illustrator and have it stay the same when updating the graph data?

I am needing to create a line graph with dates consisting of MM/DD/YY along the category axis. I would like to rotate the labels 45 degrees and have them stay when I update the graph. I have read about manually doing it, I even made an action to make it faster, but it still seems inefficient. Is there a setting that I could use to automatically create my labels as rotated? Thanks.

Hi Gravy Train,
I'm curious about why you are using 2 loops. You mentioned one is for monitoring and one is for DAQ....what do you mean by that? What is the overall goal of this piece of code. Also, I noticed that you are not closing the task. Since this is just a subset, I realize you could be closing it in your actual code, but just in case you're not.....it is very important that you close all tasks when you are down acquiring data.
