POWER CHART Problems EXPORTING data to csv file

I have a feeling that this issue is flipped and the values are automatically formatted in the Ignition DB Query Browser. For example, I just replicated your issue (using simulated tags) and looking at raw the CSV, I get values like:

1738063481806,-49.25258255004883

But when I look in the DB Query Browser, they are nicely rounded.

I did just have a look and tried some different properties on the chart to try and find a quick easy solution (Ignition based solution) but unfortunately I couldn't find one.

Until someone from IA replies the only things I can think of would be to format / transform the tag values before they are stored in history OR set the column format in Excel (as they are just really long floats) - formatting in Excel has been mentioned as a solution before:
