waveforms Strange behavior when Zooming

[Joao Paulo]

Hi Guys,

I wanted to check a signal and then when trying to zoom with the mouse wheel I have the behavior showed in the video. Looks like at a specific Zooming the rescale of the screen goes a bit crazy. Thanks in advance

The version I'm using is here:

Hi @Joao Paulo

Set the Mode manually to Repeated. If it is currently in repeated set it to shift and back to repeated. Or use Record to capture more data.
By default it will switch automatically between Repeated and Screen based on time Base. As you zoom in/out it switches the Mode and this causes the jumps.

Thank you for the observation.
I will take out this default switching behavior for the next release.

Thanks  @attila , Now I understand!

Hi,

Adding to it. I had this "ghost" marks in the video while zooming in and out. This case is jut visual, but I was being tricked in longer record because I thought there were data where shouldn't.

Then, I saved the acquisition and when I opened it there was no ghost marks.

Please, if this kind of feedback is not useful or if I'm posting in the wrong place, just let know so I can improve.

ps.: Thanks for the led brightness control implementation for DD ( I remember quoting about  the high brightness on my Roadtest )

Hi @Joao Paulo

I was unable to reproduce the issue, but some similar graphical glitch was fixed recently.
Also the UART details (start,bits,stop) won't be displayed when it won't fit (zoomed out), like the red lines in you capture.

Thank you for your observations.
