Krona 1.1 XML Specification

• Initial tags
  • Required
    • <magnitude attribute="[attr]"></magnitude>
      • This tag specifies that the [attr] attribute of each node should be used for its magnitude.
    • <attributes [attr1]="Attribute 1" [attr2]="Attribute 2"></attributes>
      • This tag specifies which node attributes will be displayed when a node is selected and how they will appear.
      • Only the attribute used for magnitude is required. Other attributes will only be displayed if they are included in this tag.
  • Optional
    • <color attribute="[attr]" valueStart="0" valueEnd="40" hueStart="60" hueEnd="360" default="true"></color>
      • This tag specifies that the nodes can be colored according to their [attr] attribute. In this example, values of [attr] from 0 to 40 will correspond to a hue gradient from 60 to 360. The default value of "true" specifies that this coloring will be enabled each time the chart is opened.
    • <datasets names="Dataset 1, Dataset 2"></datasets>
      • Specifies how each dataset should appear in the list.
      • Required if there is more than one dataset.
• Node tags
  • Nodes should be represented by nested <node> tags. The hierarchy should start with a single <node> to serve as the root.
  • The only required attributes are name and the magnitude attribute (as specified in the <magnitude> tag). The magnitude of a node has to be at least the sum of the magnitudes of nodes within it.
  • To create multiple datasets, the value of attributes can be comma-separated lists. Attributes that have a single value will use that value for all datasets.
  • Example
    • <node name="[name]" [attr1]="55,52,..." [attr2]="30,28,..." ...></node>
