Treemap Chart
A treemap displays a measure by using the sizes of rectangles in a hierarchical display.
What is a measure? What is a dimension?A measure is generally used for aggregation, for example summation, averaging, correlation, etc., within a Crosstab, Chart, Text component, or Gauge. Adding a measure to the ‘Y’ region in a chart displays the computed aggregates by using locations on the Y-axis. Adding a measure to the ‘X’ region displays the computed aggregates by using locations on the X-axis. You can also display aggregates by using color, shape, size, or label. A dimension is used to break-down the dataset into multiple groups, often within a Crosstab, Chart, or Selection List. Adding a dimension to the ‘X’ region of a Chart distinguishes the different dimension groups by location on the X-axis. Adding a dimension to the ‘Y’ region distinguishes the different dimension groups by location on the Y-axis. You can add multiple dimensions into the ‘X’ or ‘Y’ regions of a Chart, or into the ‘Rows’ or ‘Columns’ regions of a Crosstab, to create multiple grouping levels. You can also distinguish groups in a dimension by using color, shape, size, or label in a Chart. |

To create a treemap chart, follow the basic steps below:

If you are new to charting, see the following sections first: Configure Your Data…The data source for the chart (data block or data model) should represent dimensions and measures as independent columns or fields, as shown below. See Prepare Your Data for information on how to manipulate your data, if it is not currently in this form. (Note: A properly designed data model will already have the correct structure.)
In some cases (e.g., Pie Chart), you may want your data to provide just a single measure. In other cases (e.g., Line Chart), you may want the data to supply multiple measures. If the data does not provide the correct number of measures, you may be able to alter the number of measures to suit the needs of the chart by “pivoting” or “unpivoting” the data. See Pivot Data in Prepare Your Data for more information about this procedure. Open a Chart for Editing…Watch Video: Create a Chart (Open the Chart Editor)This video might show an earlier version of the feature or operation that differs in minor ways from the current version. Follow the steps below to get started with a new Chart. See Basic Charting Steps for more details.

To create a treemap chart, place the desired hierarchical dimensions in the ‘T’ region of the Chart Editor, and place the desired measure in the ‘Size’ region of the Chart Editor. Use the ‘Color’ region to distinguish particular dimension values by color.
| To create a grid of charts, place dimensions into the ‘X’ and/or ‘Y’ regions as well. See Trellis Chart (Grid) for more information. |
