Question 1

How to fill in the data format?

Accepted Answer

Fill in one data point per line, separate label and value with a comma, e.g., 'Monday,12'. Blank lines and lines that cannot be parsed as numbers are automatically ignored. Bar and line charts are suitable for showing trends and comparisons, pie and doughnut charts for showing proportions.

Question 2

Can I export images?

Accepted Answer

Yes. Click 'Download PNG' to export the current chart as a PNG image with a white background, which can be inserted into documents, PPT, or web pages. Charts are rendered locally in the browser using Canvas, and data is not uploaded to the server.

Question 3

Does it support Chinese labels?

Accepted Answer

Yes. Labels can use any text including Chinese, Japanese, etc., and the exported PNG will render normally with your device's fonts. All rendering and exporting are done locally, and the input data remains in your browser.
