缩放 C1Chart

为了在C1Chart中添加缩放行为，使用一些自定义代码在图表的MouseWheel事件处理中。

C#	拷贝代码
private void chart_MouseWheel(object sender, MouseWheelEventArgs e) { if (Keyboard.Modifiers == ModifierKeys.Control && e.Delta == -120) { chart.View.AxisX.Scale += .1; chart.View.AxisY.Scale += .1; } else if (Keyboard.Modifiers == ModifierKeys.Control && e.Delta == 120) { chart.View.AxisX.Scale -= .1; chart.View.AxisY.Scale -= .1; } }

拷贝代码

private void chart_MouseWheel(object sender, MouseWheelEventArgs e)
{   
      if (Keyboard.Modifiers == ModifierKeys.Control && e.Delta == -120)   
      {
       chart.View.AxisX.Scale += .1;
       chart.View.AxisY.Scale += .1;
       }
else if (Keyboard.Modifiers == ModifierKeys.Control && e.Delta == 120)
      {
          chart.View.AxisX.Scale -= .1;
          chart.View.AxisY.Scale -= .1;   
          }
}

为了使得用户可以在缩放时在附近移动图表，添加以下内容至C1Chart的XAML标记：

XAML	拷贝代码
<c1c:C1Chart x:Name="chart" MouseWheel="chart_MouseWheel" > <c1c:C1Chart.Actions> <c1c:TranslateAction MouseButton="Left" /> </c1c:C1Chart.Actions> </c1c:C1Chart>
