Error with loose scaling plotting the same value into WaveForm graph

[OuaisBla]

The Waveform chart when a single channel is plotted and contains only the same value over all the data history point never rescales its Y axis even when set to loose auto scaling.

I wonder why it doesn't set its range to the nearest up and down major division of the Y axis.

Its the case when Min( History Data Point ) == Max( History Dat Point )

It is a bug, or is it by design?

Thanks

Here a screen shot of what this looks like.

Hi OuaisBla,

You are seeing the current expected behavior of AutoScaleLoose. The AutoScaleLoose works on a range of points. Because your data set does not have a range (or more precisely, a range of zero) the Y-Axis is not readjusted. If you were to throw in just one point that varied from the rest of the zeros you would see the AutoScaleLoose change the Y-Axis. But since there is no measurable range the Y-Axis remains the default.
