costomize output of x axis

[B12060]

Hello All,

I have a 2D array of data  { [r,g,b,z], [6,2,9,1] }.

I would like to draw an X-Y graph where the X axis will show  [r,g,b,z]    and the corresponding values in the Y axis is [6,2,9,1].

The problem is that the XY graph now seems to restrict the X axis to consequtive numbers 1,2,3,4,5,6, etc

May I know if there is anyway to the the X axis to accept an array and display the array in the correct sequence following the array.

Thanks,
B12060

** Please don't tell me to create a list of strings and place it at the x axis area. The graph values are dynamic and change frequently so while this is possible it would require alot of programming to change the text and spacing of the indivitual strings correctly **

Hi B12060,

i see no problem to do what you want. See the attachment please. The only think you have to do is to get the arrays out ouf your 2D Array.
I hope it helps.

That doesn't really answer the question, which is actually how to get the X Scale to display text labels. The user is saying that they have a 2D array, but I think that's on paper only. They want the X Scale to display text labels such as "r, g, b, z".

See this thread.

Hi smercurio,

thanks for clarification.

Hi B1260,

what about this example?

You didn't show an example of what you really want! Do those x-values are just growing, but not evenly spaced numbers? Or any other kind of numbering?

Thanks GerdW,

Your example allows user to have control on the display of the x-axis.
However, it still rearranges the number so that 1,2,5,10 will always be arranged from smallest value to largest (even if you enter the array as  5,2,1,10)
Also it doesnt allow for strings to be the marker values.

About the graph values. Sometimes user enters 128 values, sometimes 256, or 1024  etc. So the graph markers will change dependiing on how much data user enters.

Does Labview have a graph type that plots the data according to the Y values entered but doesnt rearrange plots with regard to the values of X (instead plots according to the arrangement of the X array)?

Anyway, thanks again.

regards,

Hi B12060,

XY-graphs always use an ordered x-axis - no way to leave x-values in arbitrary order.

Possible solution: use a simple waveform graph/chart and make your own x-axis using a string indicator... Something you already mentioned in your first question

You can always use a picture control.

Hello smercurio_fc,

This would work !!

Thanks,
