Image_Graph::stackData()

Image_Graph::stackData() -- Set option that data should be stacked

Synopsis

require_once '/Graph.php';

void Image_Graph::stackData ([string/array $stackWhat = "all"])

Description

Use this function to turn on data-stacking. If $stackWhat is supplied only specific data-types will be stacked. Please note that possibly not all data-types might support stacking, in which case they will simply be left unstacked. But the base-types "bar" and "line" do support it! If you use both Y-axes then only data on the same axis can be stacked (sure!). So if you have e.g. line-data on both axes they will be stacked independently.

Parameter

string / array $stackWhat

name or array of names of data-types you want to be stacked

Throws

throws no exceptions thrown

Note

This function can not be called statically.
