How do I make a dual axis chart 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 dual axis chart show?
A dual axis chart compares two measures over a shared horizontal axis with separate vertical scales.
Definition source: Dual axis chart reference. xmetric uses its own native chart engine.
What does the dual axis chart sample show?
Choose Period, Value and Other with SUM aggregation. Before totals Value = 12 + 15 = 27 and Other = 3 + 4 = 7. Compare axis labels and units; equal screen heights do not imply equal values.

|---|---|---|---|---|---|---|
| Before | A | 12 | 20 | 3 | 2026-01-01 | 2026-01-04 |
| After | A | 18 | 20 | 6 | 2026-01-05 | 2026-01-09 |

| After | B | 24 | 25 | 9 | 2026-01-08 | 2026-01-12 |
When should I choose a dual axis chart instead of a line graph?
Use a single-scale line graph when both measures have the same units and should be compared directly.
| Chart | Use it for |
|---|---|
| Dual axis chart | A dual axis chart compares two measures over a shared horizontal axis with separate vertical scales. |
| Line graph | Use a single-scale line graph when both measures have the same units and should be compared directly. |
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 dual axis chart need?
Compare two numeric measures using a bar and a line with independent vertical axes. Start with Category or period and First measure. 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.
