class SRGGridLines: public SRGraphComponent
This grid line manager is similar to the SRGTickMarks class in that it uses a list of CPoint objects generated by the SRGraphLabelBlock-based classes to generate and position the grid lines. These grids may show major and minor lines that may have different color and line styles. A specified number of minor lines are drawn for every major line. The major lines are positioned by the tick position list.
