How do I paste from Excel or Google Sheets?
Copy the cell range, paste it into the "Paste a table" box and press "Import into table". Tab-separated (copied cells) and comma-separated (CSV) both work. A first row of text becomes the series names; the first column becomes the category names.
What if my pie chart has many slices?
Beyond eight slices the smaller rest is grouped into one "Other" slice, because more colors stop being distinguishable. To show everything, use a bar or horizontal bar chart.
Can I make a dual-axis chart (two y-scales)?
No. Dual axes invite readers to see meaning where two lines cross, which is misleading. Put measures with different units in separate charts side by side.
Can the y-axis start somewhere other than zero?
No. Bars encode quantity by length, so a non-zero baseline exaggerates differences. To highlight small differences, use a line chart with value labels on.
Can I change the colors?
Yes – use the color swatch next to each series name. The default eight are ordered so adjacent colors remain distinguishable for people with color-vision deficiency.
Is my chart saved?
It is saved in this browser and restored next time. To open it on another device, use "Copy share URL" – the URL carries the data.
