Stacked Bar Chart Guide
A stacked bar chart stacks multiple series on one bar: bar height is the total and color blocks show composition.
| Element | Description | Suggestion |
|---|---|---|
| Category Axis | Shows category names on the horizontal axis | Keep categories below 12 for clarity |
| Series | Each series is one stacked color layer | Keep 3-6 series for readability |
| Legend | Maps colors to series | Move the legend to avoid overlap with many series |
| Total | Overall bar height represents the total | Turn on labels when totals matter |
FAQ
A stacked bar chart stacks multiple series on the same bar. The total bar height shows the overall value while colored segments show each series, making it great for composition and totals.
Click Edit/Upload Data to fill in or import data (first column: category name, first row: series names), adjust legend, title and label parameters with real-time preview, then click Download Chart to export.
You can edit data directly in the table, or upload Excel (.xlsx/.xls) and CSV files. The first column is category names and the remaining columns are series values.

The stacked bar chart renders in real time in your browser - with moderate data volumes you get instant previews and see every parameter change immediately.
No. All data processing happens locally in your browser and nothing is uploaded, so your privacy is fully protected.
