The stacked area chart is like a line chart, but values are ordered and stacked with smaller values on the top. This is useful for comparing related values in context while preventing some values from being hidden by overlapping.
Click Chart settings to configure the properties for a stacked area chart.
| Setting | Description |

| Encoding | Configure how the data is mapped to the X and Y axes.
Select Horizontal chart to change the visualization to a horizontal line chart. |
| Axis | Provides the following options:
- Show/hide the labels for the X and Y axes.
- Show/hide the X and Y axes grid lines.
- Select Fit to Data to have the line chart fill up the white space in the chart.
