Weird Lines in Data Browser Plot

[caraxlr]

Hi,

We've noticed some strange line artifacts in the Data Browser. For example, in this plot there are some unusual lines that disappear when the trace is set to raw data.

I was wondering if you might have any ideas about what could be causing these artifacts, and whether they might be related to the data optimization.

Also, it seems that there is currently no preference available to set raw data as the default. Would it be possible to add a preference for this?

Thanks a lot,
Lingran

Open the sample viewer and check if the data contains samples which are out of order, not sorted in time.

The data optimization is basically done by the archive. Which one are you using? The data browser asks for optimized samples and then displays the result.
