Multiple Real-Time Curves Not Overlapping Properly

[Uwe]

No you don't see anything as the x axis is disabled.

I would guess, that you have autoscaling enabled and the x-axis changes, when you enable/disable a curve: try your application with having the x axes visible.

No this is not happening - nobody fills rectangles when drawing a curve. It looks more like that the bounding x interval of the curves is different: check your samples.

I captured three videos showing what is happening. The first two videos show the separate single plotted curves. The third video shows the two curves together in QWT and demonstrates the issue I am having.

Hello, yes autoscaling is on and the x-axis was disabled. I tried enabling the x-axis and the plotted curves are still alternating on one half of the plot.

Of course they do, but is the axis range changing, when you enable/disable curves ?

More interesting than your videos are the bounding rectangles of your curves: I'm pretty sure the x interval is different: the x coordinates of the second curve are above the first.

Sorry Uwe, I just understood what you meant. I set the same x values for both curves and everything is fine.

Thanks for your help and patience.
