Frequently Asked Questions
How do I add data to the chart?
Edit cells directly in the spreadsheet grid at the top. The first column is for category labels (like Q1, Q2, etc.), and the remaining columns are numeric data series. Use the + Row and + Column buttons to expand the grid. All charts update instantly as you type.
What chart types are available?
Five chart types are generated simultaneously: vertical bar chart, horizontal bar chart, line chart, pie chart, and doughnut chart. Each uses the same data from the grid.
How do I download a chart as an image?
Each chart has a "Download JPG" button in its top-right corner. Click it to save that chart as a JPEG image with a white background, suitable for presentations or reports.
How does the pie chart handle multiple data series?
The pie and doughnut charts sum all data series for each category to create one value per slice. For example, if Q1 has values of 120, 80, and 95 across three series, the Q1 slice represents 295.
Is my data saved or uploaded anywhere?
No. All data stays in your browser. Nothing is sent to any server. When you close the tab, your data is gone.
