Set number of major ticks to a predefined value in a WaveForm Graph

[mforbiz]

Hi!

Is there any way to set the number of major ticks in a waveform graph to a fixed value (i.e. 10  major thicks : 0, 10, 20, 30,...., 100) ?

Any idea?

Thanks in advance

First, you'll need to make sure the graph is big enough to be able to handle that many ticks.

Then you can programmatically set the increment between ticks.  But you aren't going to be able to add more than will fit.

(This looks at all range values, but you could set the property node to just XScale.Increment if you wanted to.)

Hi!

Thanks for your reply.ùMay you share this VI?

Thanks in advance

It's a snippet.  Save the PNG file to your desktop, drag file into a block diagram  (assuming you have LV 2019).

It is easy to create.  The Xscale property is way down on the list when you go to select the property in the property node.

Hi!

Thanks for your reply.

It works but I don't understand how it works.

I'm a teacher.

I must know how a program works to teach it to my students.

For example I don't understand why Xscale.Range there is two time or what is "increment" and so on...

May you help me?

Thanks in advance.

P.S. Thanks for snippet are very useful.

You can open up context help and hover over that property node and look up the items. You may need to drill down into detailed help.

What do you mean by "I don't understand why Xscale.Range there is two time"?

Do you man that there is two different properties with the word "increment" in them?  Increment is the interval between the numbers and the bolder grid lines.  Minor increment is the interval between the fainter grid lines.

Ok. Now I've understand all.

Your solution works fine !

Thanks
