Mutiple Y axis on waveform chart problem

[govindsankar]

I have a simple problem with multiple y axis on a waveform char. I will post the screenshot of the program here. 

As you can see I am giving values to it using random number generator. But the important thing is not that. The important thing is me trying to set the y axis plot name and ysale maximum and minimum for both plot 0 and plot 1. 

But as you can see from the picture only plot 1 is changed with my programing. Plot 0 remains the same as in the start. Why is that or how can I update plot 0 to have user defined ymax, ymin and name programmatically.I have also attached the program, just in case, but i doubt its needed, you get the whole thing from the pictures itself.  Thank you.

Hi Govindsankar,

You forgot to set the active scale before changing the properties of the active scale!

I didnt forget, actually I didnt know about this. Even whatever I did, I did using googling and it didnt say about setting active scale. But your solution worked for my program. Thank you. But actually this was done to make corrections to a bigger program with actor framework and there it is still not working. Not sure why. But anyway, I will try something around, and if i cant find the solution I will get back to you. There I am actually creating a method VI for the actor and the VI contains the reference to the waveform by unbundling the actor and using property node i set the properties like you said. And then I create a message out of it and run it using the actors self enqueuer. But somehow its not working. I know the data I have given is not enough. But as I said I will work on it and try to find where I went wrong and if i cant find it, i will come back here on that. Anyway thank you very much for this.

So you did know you need to set the ActivePlot before changing properties for the plots - but you didn't know you need to set the ActiveScale before changing its properties?
