Question 1

What is a stacked bar chart (100% stacked bar chart)?

Accepted Answer

A stacked bar chart is well suited for comparing the composition ratio of each item relative to the whole. Each bar always totals 100%, and it shows how large a proportion each data item occupies within that bar, stacked in a band. For example, it is useful for comparing the sales composition ratio of products A, B, and C (segments of the band) for each month (bar) to visually grasp which product was strong in which period. It is especially effective when you want to emphasize proportions relative to the whole rather than simple changes in values. If you want to show simple changes in values, we recommend using charts like the following. Bar Chart Line Chart If you want to show a single composition ratio, the following charts are suitable. Pie Chart Donut Chart

Question 2

How do I enter and edit the chart data?

Accepted Answer

In the "Data Input" section, you can edit the tabular data directly. Adding/deleting rows: Enter a new label and value in the input fields below the table and press the "Add" button to add a row. Use the "×" button on the right of each row to delete that row. Adding/editing/deleting columns: Click the pencil icon next to each column label to change the column's name or color, or delete the column itself. Use the "+" button on the far right to add a new column. Changing values: Click directly on each cell value in the table to change it. The chart updates in real time.

Question 3

Sometimes the percentage isn't displayed even when I turn on "Show proportions on bars". Why?

Accepted Answer

To keep the chart looking clean, percentages are intentionally not displayed on bar segments whose proportion is too small. Specifically, when an item's proportion is less than 5% of the whole, or the bar is too narrow for the text to fit, the label is automatically hidden.
