FAQ
Violin Plot Maker questions
- Violin plot or box plot?
- A box plot gives you five exact numbers. A violin plot shows the whole shape, which is the only way to spot two peaks in the same group. Use a violin when shape matters and a box when you need precise quartiles.
- How is the density curve calculated?
- With a Gaussian kernel density estimate whose bandwidth is derived from the spread of each group. The interquartile range and median are overlaid so you still get the summary statistics.
- How many points do I need per group?
- At least three to draw a curve, but the shape only becomes meaningful with roughly twenty or more points per group.

Paste from anything
- CSV to ChartPaste raw CSV text or drop a .csv file. Delimiters, quoted fields and header rows are detected automatically.
- Excel to ChartSelect cells in Excel, press Ctrl+C, then paste here. Copied spreadsheet cells arrive as tab-separated values, which FastChart reads natively.
- JSON to ChartPaste an array of objects, an array of numbers, or a flat key–value object. Keys become series and values become data points.
- Markdown Table to ChartGreat for tables produced by ChatGPT, GitHub READMEs or Notion. Pipes and the separator row are handled for you.
- TSV to ChartTab-separated values are what your clipboard holds after copying from a spreadsheet or a database client. Paste them straight in.
- Google Sheets to ChartGoogle Sheets charts are hard to style and hard to export cleanly. Copy the range instead and get an export-ready chart here.
