Charts

Data and chart update directly. Paste CSV or TSV under Data, then choose X and Y columns. The sample is editable; your raw data and column choices stay in this browser, generated charts do not.

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.

SVG download preserves displayed colors and the chart. Up to 200 rows; no data is silently sampled. Changing X removes it from Y selection; choose any additional Y columns explicitly.

Use labels of at most 256 characters.

Changing data clears the old plot immediately and updates after a short typing pause; Ctrl/⌘+Enter updates immediately. The plot fits the available width and screen height; on a phone it scrolls horizontally to keep labels readable.
