For information on how to place two dimensions on Colour in a treemap, see Example – Multiple Fields on Colour. But beyond that, adding dimensions only breaks the map into an ever greater number of smaller rectangles. Treemaps can accommodate any number of dimensions, including one or even two on Colour. You can place measures on Size and Colour, but placing a measure anywhere else has no effect. With treemaps, Size and Colour are the crucial elements. The chart supports various chart types such as. It is useful when you would like to utilize modern browser technologies such as SVG or Canvas (with a fallback to VML for older IE versions) for interactive data visualizations. Now Profit determines the colour of the rectangles, and Sales determines their size: The Kendo UI chart is a data visualization widget which allows you to output a graphical representation of your data.
Try another option to modify the treemap: click the Undo button to remove Ship Mode from view.ĭrag the Profit measure to Colour on the Marks card. Sales determines the size of the rectangles: In the resulting view, Ship Mode determines the colour of the rectangles – and sorts them into four separate areas accordingly. In this treemap, both the size of the rectangles and their colour are determined by the value of Sales – the greater the sum of sales for each category, the darker and larger its box.ĭrag the Ship Mode dimension to Colour on the Marks card. Tableau displays a bar chart – the default chart type when there is a dimension on the Columns shelf and a measure on the Rows shelf.Ĭlick Show Me on the toolbar, then select the treemap chart type. Tableau aggregates the measure as a sum and creates a vertical axis. To create a treemap that shows aggregated sales totals across a range of product categories, follow the steps below.Ĭonnect to the Sample - Superstore data source.ĭrag the Sub-Category dimension to Columns.Ī horizontal axis appears, which shows product categories. The basic building blocks for a treemap are as follows: Mark type: Treemaps are a relatively simple data visualisation that can provide insight in a visually attractive format. You use dimensions to define the structure of the treemap, and measures to define the size or colour of the individual rectangles. Use treemaps to display data in nested rectangles.
