How do I make a slope chart from my data?

What does a slope chart show?
A slope chart connects each category between two periods to show its change.
Definition source: Slope chart reference. xmetric uses its own native chart engine.
What does the slope chart sample show?
Choose Period, Value and Category as the series. A moves from 12 Before to 18 After, an increase of 6; B moves from 15 to 24, an increase of 9.

When should I choose a slope chart instead of a line graph?
Choose a line graph for more than two periods. This slope maker requires a source containing exactly two periods.

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 slope chart need?
Connect each category across exactly two periods. Bring a file containing only the two periods you want to compare. Start with Period and 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.
