Key – legends for key

Specifies the text key for each line or group of bars. May also be used to key a piechart if preferred to spider labels.

chSet 'Key' 'North,South,East,West'

Note: If you use a semi-colon as the first character of a key, this forces the key onto a new line, or a new column in keys with the ‘vertical’ style. (see Praxis for an example).

chSet 'Key' 'North,South,;East,West'

Semi-colons used in the body of the key text split the text onto multiple lines – preceed the semi-colon by a backslash to have the legend include a semi-colon character. If you give more text elements than will fit into the available space, the default behaviour is to discard the over-flowed text. Set the KeyStyle to ‘Autofit’ to have RainPro reduce the font-size of the key text until all the legend fits correctly.
