Reporting a problem with a chart

To help us fix issues quickly, please include:

• The chart maker you were using (its web address).
• Your browser and device.
• What you expected, and what happened.
• If you are comfortable sharing it, the chart file from Saved charts → Download chart file (.json). Please remove any confidential data first.

Because your charts are processed only in your browser, we can’t see or recover your data. Please keep your own copies.
