Frequently asked questions

How do I show multiple series?

Add multiple series names in the first CSV row; the tool creates one dataset per series.

Can I change the line color?

Yes. Use the accent color picker; other series receive distinct supporting colors.

Does area mode change the data?

No. Filling changes only the visual treatment; values remain those in your table.
