Scenario of reading color scheme for a graph:

The color scheme file is [installation directory]\esProc\classes\config\chartcolor.properties. A color scheme format is color scheme name=[color1,color2,….]:

 

Set colourful8 as the color scheme for the column graph:

 

Note:

To use the color schemes in plotting a graph, make sure that the class path can be loaded onto the config directory. esProc default design is that the config directory is already put into [installation directory]\esProc\classes. To view the effects of color schemes on server side, users need to create a config folder in the service’s [applicaton root directory]\WEB-INF\classes unless there’s already a config folder there and copy the color scheme file chartcolor.properties under it.
