Jump from data point to data point within Signal-Plot instead of a fixed timeintervall of 100ms

Feature-request:
Jump from data point to data point within Signal-Plot instead of a fixed timeintervall of 100ms

This request is similar to:
#452

When working with Signal-plots you rather want to step to the next data point and not the standard fixed time interval of 100ms.
At the end we should be able to calculate the delta_time to the next data point and just jump this amount.

• This can be done automatically when we select a plot window
• This can be a small button like mentioned within Add button to step to next message in topic #452

Due to image size restriction of <10kb I can only upload a very small example:

--> you will always jump 100ms and potentially overjump a measurement point. When working with plots a lot of the time we actually don't want to jump this 100ms fixed time but rather just jump to the next data point.

Hello @DFKChris, thanks for reaching out!

Great point, we have already this on the roadmap about jumping to the next message. I believe when we implement it we will not need to do it specifically for the chart, so you can achieve that. I can't say when we are going to to implement this, but it is on our goals :)

Additionally, you can use shortcuts like shift + left / right, and you can jump 10ms, if a shorter timestamp is desired or alt + left / right to jump 500ms. Maybe this can help you a little bit: https://lichtblick-suite.github.io/docs/visualization/shortcuts.html

thanks for the understanding and participation on our open source project! You can also try to implement it yourself if you want, we will be more than happy to analyze and merge your PR!

Cheers,
Alex
