Axis Unit

The AxisUnit node controls placing of a unit tag on an axis. The tag is the value of the Title attribute in the node. By default, it is empty.

The axis unit is used for labeling only; it has no other effect on the chart.

Setting the Axis Unit

In this example, the axis unit for the x-axis is set to "hours" and the axis unit for the y-axis is set to "meters". While not required, the axis titles are also set.

public class SampleAxisUnit : FrameChart {

    public SampleAxisUnit() {
        Chart chart = this.Chart;
        AxisXY axis = new AxisXY(chart);
        double[] y = {4, 2, 3, 9};
        Data data = new Data(axis, y);

        axis.AxisX.AxisTitle.SetTitle(“Time”);
        axis.AxisY.AxisTitle.SetTitle(“Height”);

        axis.AxisX.AxisUnit.SetTitle(“hours”);
        axis.AxisY.AxisUnit.SetTitle(“meters”);
    }

    public static void Main(string[] argv) {
        System.Windows.Forms.Application.Run(new SampleAxisUnit());
    }
