XtraCharts > 示例 > 如何： 定制轴的网格线和刻度线

本示例演示了在运行时刻如何定制 轴 的 网格线和刻度线。

要访问轴，则应该把图表的 图象 对象转换为所需的图象类型。 然后，使用 Axis2D.Tickmarks 和 AxisBase.GridLines 属性来访问相应的元素。 要指定 minor 刻度 (网格线) 的数目，则使用 AxisBase.MinorCount 属性。

// Cast the chart's diagram to the XYDiagram type, to access its axes.
XYDiagram diagram = (XYDiagram)chartControl1.Diagram;

// Customize the appearance of the axes' tickmarks.
diagram.AxisX.Tickmarks.CrossAxis = true;
diagram.AxisX.Tickmarks.Length = 5;
diagram.AxisX.Tickmarks.Thickness = 2;

diagram.AxisY.Tickmarks.Visible = false;
diagram.AxisY.Tickmarks.MinorVisible = false;

diagram.AxisX.Tickmarks.MinorLength = 3;
diagram.AxisX.Tickmarks.MinorThickness = 1;

diagram.AxisX.MinorCount = 2;
diagram.AxisY.MinorCount = 4;

// Customize the appearance of the axes' grid lines.
diagram.AxisX.GridLines.Visible = false;
diagram.AxisX.GridLines.MinorVisible = false;

diagram.AxisY.GridLines.Visible = true;
diagram.AxisY.GridLines.MinorVisible = true;

diagram.AxisY.GridLines.Color = Color.Red;
diagram.AxisY.GridLines.LineStyle.DashStyle = DashStyle.Solid;
diagram.AxisY.GridLines.LineStyle.Thickness = 2;

diagram.AxisY.GridLines.MinorColor = Color.Blue;
diagram.AxisY.GridLines.MinorLineStyle.DashStyle = DashStyle.Dash;
diagram.AxisY.GridLines.MinorLineStyle.Thickness = 1;
