drawing_mode attribute of node in Treemaps defines how branches headers and data item labels are displayed. It defines whether branches will expand their content on all chart when they are clicked, or not.Īlthough treemaps give a great opportunity to show a lot of data in a limited space, you can't always place all texts on the chart. node has enable_drilldown attribute which can be 'true' or 'false'. It can be 'asc', 'desc' - default, and 'none' - you will get 'as they go' in XML file order. Russian 150000000 Ukraini 45000 Polish 5500000 C S Serb Bul East Slavic West Sou Slavic Languages Treemap: Headers Slavic Languages by Number of Speakers. node has sort attribute, which defines how sub-nodes of each branch are sorted. There are several special things about treemap charts.įirst of all there is a special node in style that defines how tree branches are shown, you can define, , and for them - so user can easily distinguish them among other elements. You can either visualize linear and hierarchical data using An圜hart treemaps, if, for example, you have the following data set listing countries population: Roman Lubushkin introduces you An圜hart, demonstrating its powerful API and visually appealing chart types by means of 10 easy-to-follow examples. Let's now edit the hovering settings of a TreeMap: create markers of 'star5' type which will be displayed on the hovered points. selectMarkers () methods, adjusting markers in different chart states. The illustration below shows structure of Treemap charts in An圜hart: Markers in the TreeMap charts are configured using. You can define how many levels do you want to be shown simultaneously on a chart.

Treemaps in An圜hart are build using a special plot_type named'TreeMap'. An圜hart TreeMaps have a Maximum Depth feature. As a result, they can legibly display thousands of items on the screen simultaneously. A second advantage of treemaps is that, by construction, they make efficient use of space. When the color and size dimensions are correlated in some way with the tree structure, one can often easily see patterns that would be difficult to spot in other ways. Often the leaf nodes are colored to show a separate dimension of the data. A leaf node's rectangle has an area proportional to a specified dimension on the data. Each branch of the tree is given a rectangle, which is then tiled with smaller rectangles representing sub-branches. Treemaps display hierarchical (tree-structured) data as a set of nested rectangles.
