CHART PLAYGROUND
Start with an original example. Edit its data and settings, then apply your changes to the displayed chart.
PLAYGROUND DATA EDITOR
Edit a value or paste a rectangular block from Excel into a value cell. Empty cells become null. Changes reach the chart only when you apply them.
Select a button to open that layer’s data table and colour controls below.
Edit existing scalar settings from this example. Option paths identify exactly what changes; structured values and JavaScript callbacks remain intact.
Paste values only, or a table copied here with its headings and unchanged first category/time column. The existing row and column counts must match. For a different data structure or row count, use the original data JSON below.
Custom fields remain intact. Edit the original structure here when it cannot be represented as numeric table cells.
Add a JSON options patch. These values merge into the current chart; title, theme and legend controls take precedence. JavaScript callbacks remain in the original example.
JSON only, up to 16 MiB per editor. Complete data up to 250,000 points and 8 MiB per chart, with 16 MiB total transfer. Larger stress tests keep all data in the original frame. No JavaScript evaluation or server transfer.
This editor needs JavaScript. Browse the original examples.
