XY Chart issue with Zoom

Hi All,

I have a strange issue when the XY Chart gets zoomed in.
Pictures can talk better than me :wink:

This is a 1Hz pulse and the green line has to stay in between the red and yellow line. As you can clearly see, between 100 ms and 200 ms, the green line almost hits the yellow line. So, since I want to know I zoom in and then this happens:

the chart is showing me that the green line wasn’t inside the yellow line. But as you can see in the first picture, the green line always stays inside the other two.

Some explanations?

Cheers and thanks in advance :slight_smile:
