What does a bubble chart show?
A bubble chart uses numeric coordinates for position and another numeric field for mark size.
Definition source: Bubble chart reference. xmetric uses its own native chart engine.
What does the bubble chart sample show?
Choose Period as X, Value as Y and Size for bubble size. The first sample row gives coordinates (1, 12) and a size value of 3.

| 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 bubble chart instead of a scatter plot?
Choose a scatter plot when you only need the two position fields and no extra size encoding.

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 bubble chart need?
Compare numeric coordinates and encode a third numeric column as bubble size. Start with X value and Y value. 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.
