Inconsistent behavior of Curve2DPreview object with YAxisScalingType

[franco__]

I'm trying to plot a couple of DIAdem curves with VBScript. The only tool I found is the "Curve2DPreview" object.

The curves are an exponential decay of voltage. When shown in linear scale, they look like this: 

I put a button next to the plot to change to Log scale, and when I do the result is the following:

Does anybody know how to solve this issue, and get the plot in the right possition?

More information: I have DIAdem2015, the four curves are waveform curves.

Thanks

Hello franco___

I tested this with DIAdem 2015 SP2, but was not able to reproduce it. Attached you find my test SUD which uses the Example data. If this doesn't help we need your SUD and the data.

Hi Walter,

Thank you for your answer. I believe I may have been unclear in my original submission, I only wanted the "Y" channel to be in log scale, and the "X" channel to keep the linear scale.

When I modify your SUD to keep the "X" channel always in linear scale I get the same results I got before.

For clarification: Linear-Linear scale (works ok) :

 Log-Log scale (works ok):

Log-Linear scale (doesn't work):

And the same three scale combinations but in the standard DIAdem viewer:

Hi franco__,

You are right this is not correct. The only work-around is to convert the waveform channel into a X/Y channel pair and display this. I hope we can fix the proble for the next DIAdem release.

That worked, thanks!
