有时,用户需要知道图表中是否存在特定的轴。例如,他想知道图表中是否存在次要值轴。有些图表,比如饼图,爆破饼图,饼-饼图,饼图-柱状图,3D饼图,3D爆破饼图,圆环图,爆破圆环图等,是没有轴的。
Aspose.Cells提供了Chart.HasAxis(AxisType axisType, bool isPrimary)方法来判断图表是否具有特定的轴。
以下示例代码演示了如何使用Chart.HasAxis(AxisType axisType, bool isPrimary)来确定示例图表是否具有主要和次要类别和值轴。

Console.WriteLine("Has Primary Category Axis: " + ret); | |
ret = chart.HasAxis(AxisType.Category, false); | |
Console.WriteLine("Has Secondary Category Axis: " + ret); | |
ret = chart.HasAxis(AxisType.Value, true); | |
Console.WriteLine("Has Primary Value Axis: " + ret); | |
ret = chart.HasAxis(AxisType.Value, false); | |
Console.WriteLine("Has Secondary Value Axis: " + ret); |
示例代码生成的控制台输出
代码的控制台输出如下所示,显示主类别和值轴为true,次要类别和值轴为false。
Has Primary Category Axis: True
Has Secondary Category Axis: False
Has Primary Value Axis: True
Has Secondary Value Axis: False
