Class Details

[line 51]
A grid displayed on the plotarea.

A grid is associated with a primary and a secondary axis. The grid is displayed in context of the primary axis' label interval - meaning that a grid for an Y-axis displays a grid for every label on the y-axis (fx. a {@see Image_Graph_Grid_Lines}, which displays horizontal lines for every label on the y-axis from the x-axis minimum to the x-axis maximum). You should always add the grid as one of the first elements to the plotarea. This is due to the fact that elements are "outputted" in the order they are added, i.e. if an grid is added *after* a chart, the grid will be displayed on top of the chart which is (probably) not desired.
