# Multi dimension charts A multi dimension chart splits your data by two dimensions at once, so you can compare categories within categories. For example, a clustered column chart could show the number of supporters in each region, with a separate column for each age band. For how dimensions and measures work, see [Dimensions]() and [Measures](). ## Add a multi dimension chart Most multi dimension charts need two dimensions and one measure. Combo charts need two dimensions and two measures. The **Multi Dimension Charts** group also has the cube, which has its own page. See [Cube tiles](). To add a multi dimension chart: 1. [Add a tile]() and choose a chart from the **Multi Dimension Charts** group as the **Tile Type**. 2. Under **Dimensions**, add two dimensions. 3. Under **Measures**, add the measure, or two measures for a combo chart. 4. Select **Apply**, then **Save** the dashboard. Until the chart has the dimensions and measures it needs, the tile editor shows a warning, such as `Chart requires 2 dimensions.` To show which colour belongs to which category, turn on **Legend** under **Tile Settings**. The chart's colours come from the [dashboard's theme](), and an admin can also give particular categories their own [category colours](). ## Chart types Each chart type compares the categories of two dimensions in a different way. ### Clustered column A clustered column chart shows a group of columns for each category of the first dimension, with a column for each category of the second. The vertical axis shows the measure. ### Stacked column A stacked column chart stacks the second dimension's categories into one column for each category of the first. The vertical axis shows the measure. ### 100% stacked column A 100% stacked column chart is a stacked column chart where every column adds up to 100%, so you compare proportions rather than totals. ### Clustered bar A clustered bar chart is a clustered column chart turned on its side. The horizontal axis shows the measure. ### Stacked bar A stacked bar chart is a stacked column chart turned on its side. The horizontal axis shows the measure. ### 100% stacked bar A 100% stacked bar chart is a stacked bar chart where every bar adds up to 100%. ### Clustered line A clustered line chart draws a line for each category of the second dimension across the categories of the first, such as years. The vertical axis shows the measure. ### Clustered area A clustered area chart is a clustered line chart with the area under each line filled in. ### Stacked area A stacked area chart stacks the filled areas on top of each other, so the top edge shows the total. ### 100% stacked area A 100% stacked area chart is a stacked area chart that always adds up to 100%. ### Clustered combo A clustered combo chart shows two measures. The left axis shows the first measure as clustered columns, and the right axis shows the second measure as a line for each category of the second dimension. ### Stacked combo A stacked combo chart shows the first measure as stacked columns, and the second measure as a line for each category of the second dimension, on the right axis. ### 100% stacked combo A 100% stacked combo chart shows the first measure as 100% stacked columns, and the second measure as a line for each category of the second dimension, on the right axis.
