Frequently asked questions

What chart types are available?

Bar, line, pie and doughnut — the most common types for simple label/value comparisons.

Can I import data from a spreadsheet?

Not yet — data is entered directly as label/value pairs in the tool.

What format does it export as?

PNG image, ready to drop into a document, slide or blog post.

Is there a limit to how many data points I can chart?

No hard limit, though charts with very many labels get harder to read — keep it to what fits legibly on one chart.
