How do I make a histogram from my data?
Choose a local CSV, Excel, JSON or Parquet file, or paste CSV with a header row. Choose the fields in the controls to draw and edit your chart; xmetric processes the data in this browser.
No data loaded. Choose your own file or try the sample.
What does a histogram show?
A histogram counts numeric observations within equal-width bins.
Definition source: Histogram reference. xmetric uses its own native chart engine.
What does the histogram sample show?
Choose Value with bin width 10: values 12, 18 and 15 fall in [10, 20); values 24, 20 and 28 fall in [20, 30). Each bin contains 3 observations.

| Period | Category | Value | Other | Size |
|---|---|---|---|---|
| 1 | North | 12 | 8 | 3 |
| 2 | South | 18 | 13 | 6 |
| 3 | North | 15 | 17 | 4 |
| 4 | South | 24 | 21 | 9 |
| 5 | North | 20 | 19 | 5 |
| 6 | South | 28 | 30 | 8 |
When should I choose a histogram instead of a frequency table?
Choose a frequency table to count category labels rather than intervals of a numeric measure.
| Chart | Use it for |
|---|---|
| Histogram | A histogram counts numeric observations within equal-width bins. |
| Frequency table | Choose a frequency table to count category labels rather than intervals of a numeric measure. |
What limits apply to my data?
These limits apply to tabular imports, not native Power BI or Tableau report compatibility. File size and browser memory limit what xmetric can open. Group large datasets before drawing a chart.
| Limit | Current behavior |
|---|---|
| File size | 32 MiB on constrained devices; 160 MiB otherwise |
| Imported rows | Up to 3,500,000 |
| Chart marks | Up to 10,000 |
| Download | SVG chart |

Can I chart a CSV without uploading my data?
Yes. xmetric reads the selected file or pasted CSV in your browser. Opening and editing this local chart does not upload the file.
Which columns does this histogram need?
Count numeric observations in equal-width bins you can edit. Start with Numeric observations. Choose the additional series, target or date fields when the controls request them.
Can I export the chart and keep editing it?
Yes. Download SVG for a static chart, or choose Continue editing in xmetric to carry the data and selected chart into the app. Check the chart before sharing it.
