Gets or sets a Grid object used to set the major grid line properties for an axis.
Assembly: System.Web.DataVisualization (in System.Web.DataVisualization.dll)
Major grid lines are always drawn in conjunction with a data point. That is, they will occur at the same point along an axis as a data point, for categorical axis tick marks. For value axes, major grid lines by default are drawn wherever labels occur.
You can use this property to change major grid line frequency, color, and so forth.
