Hello and thanks for the answers!

This graph control is really not an easy solutions because I have to take care when the labels overlap and when the user zooms into the graph I have to recalculate everything.

Has anyone already made all that work or do I really have to make it.

Thanks anyway!

You set y-axis markers the same way you set x-axis markers. Can you show us the code you have? It's always eaiser to understantd your issue and make suggestions if we've got your code to work with.

Hello,

I made an example, it should show what I mean. The x-Scale should then be 0,1,2,0,1,2 (just in this example) and not 0,1,2,3,4,5,6,7,8,9.

Cheers,

Hello,

I have a graph and need to change the x scale markers:

On the x scale I show the "sample number" and the user can select which one he wants to see. So for example 1,2,50,80. So the xscale should be like:

|.....|.....|.....|

1... 2....50...80

If I use the property to set the markers, I get something like:

|..|...........................|..................|

1.2..........................50................80

Is there a possibility to set a marker for every value in the y-array?

In the NI-forum I got the answer to use a picture control (draw a picture by myself with the right markers) but that's quite complicated, do you have another idea?

Thanks,

Rico

@Guenther:

Your code works good, but I now found an even easier way, it is possible to use a cursor and set it to snap to all plots. So you can just move the cursor and it will snap to the nearest plot and show its name. Thanks anyway!

Hi Osiris,

for another project I coded a sub-VI that will give you the nearest data point for a given coordinate. So you make a mouseclick on the graph, close to the plot you're interested in, and the sub VI will give you X and Y value of the nearest data point plus the numer of the plot with this data point. This way you should be able to identify the strange graph. Sample is attached.

Have fun,

Guenther

Hello Guenther,

Thanks a lot! I will test and and write if I have success with it, it really sounds exactly what I need, thank you!

Something besides color, point and line style? Or are you looking at specifically naming each plot as the user mouses over it? I haven't seen that done yet.

hello, yes, it should work the other way, I click on the graph and get the plot name. Normally, all plots have the same waveform (+ some noise) but some have a totally different and I should identify them. It would be easy to select them, if LabView's Graph would support something similar than the charts in Excel (or most graphs/charts do by just showing the name when the mouse is over the plot)

Hello,

I have a multiplot waveform graph and the user would like to identify one plot on it (for example, 1500 plots, one totally different then the others and the user wants to know which one it is). In an excel chart you can simply move your mouse over a plot an get the plot name. There is no such possibility in Labview, but is there anything else to identify a plot?

Thanks,

Rico
