Question 1

What is a 100% stacked area chart?

Accepted Answer

A 100% stacked area chart is a chart suited to visualizing the change in each item's composition ratio over time or along a category order. The total height of the chart is always 100%, within which the proportion occupied by each data item is shown as color-coded areas. For example, it is useful for representing the change in market share year by year, or the change in the proportion of each task in a project's progress. It is similar to a 100% stacked bar chart, but an area chart is better suited to emphasizing the continuity and trends of the data. If you want to compare the change in actual values rather than composition ratios, we recommend using a stacked area chart or a line chart.

Question 2

How do I enter and edit the chart data?

Accepted Answer

In the "Data Input" section, you can directly edit the tabular data. 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's label to change the column's name or color, or to delete the column itself. From the "+" button on the far right, you can add a new column. Changing values: You can directly click and change the value of each cell in the table. The chart updates in real time.
