Charts

Paste CSV or TSV with a header, select the X column and Y series, then draw. Include units in column headers; all Y series share one scale and should use the same unit.

Bar and line charts keep the input row order and treat X as category labels. Scatter uses numeric X positions. Missing or invalid numbers are rejected, never replaced with zero. Decimal points or commas and scientific notation are accepted; use semicolons, tabs or quoted cells for decimal commas. Thousands separators are not supported.

Up to 200 data rows, 9 columns and 200,000 characters. No data is sampled or omitted. Long or dense axis labels are shortened; full labels and values are in the table. Sorting the table does not reorder the chart. Editing clears the result until you draw again. Export and larger datasets are not included.
