使用两组不同的值绘制单个 X 轴 - 图表 - WPF Codeplex
我正在使用两组不同的 X 和 Y 值绘制 XY 图。这就是我的数据集的样子 -> [ X1 = {1,3,5,...}, Y1 = {104, 98, 36,....} 且 X2 = {2,4,6..}, Y2 = { 76, 65, 110 ..}]。
这是我正在使用的代码：
series1.DependentValueBinding = new System.Windows.Data.Binding("Y1"); series1.IndependentValueBinding = new System.Windows.Data.Binding("X1");
series1.DependentRangeAxis = YAxis;
series1.IndependentAxis = XAxis;
series2.DependentValueBinding = new System.Windows.Data.Binding("Y2"); series2.IndependentValueBinding = new System.Windows.Data.Binding("X2");
series2.DependentRangeAxis = YAxis;
series2.IndependentAxis = XAxis;
此代码适用于将两个系列分配给单个 Y 轴，但是当将具有不同 X 和 Y 值的两个系列分配给 X 轴时，它会弄乱第一个系列。它相对于 X2 = {2,4,6..} 绘制 Y1 = {104, 98, 36,....} 和 Y2 = { 76, 65, 110..}，而不是相对于 X1 绘制Y1 和 X2 相对于 Y2 且只有一个 X 轴和 Y 轴。
请建议我如何将两组不同的值分配给单个 X 轴。
先感谢您！

I am plotting a XY graph with two different sets of X and Y values. This is how my dataset looks -> [ X1 = {1,3,5,...}, Y1 = {104, 98, 36,....} and X2 = {2,4,6..}, Y2 = { 76, 65, 110..}].
This is the code I am using:
series1.DependentValueBinding = new System.Windows.Data.Binding("Y1");
series1.IndependentValueBinding = new System.Windows.Data.Binding("X1");
series1.DependentRangeAxis = YAxis;
series1.IndependentAxis = XAxis;
series2.DependentValueBinding = new System.Windows.Data.Binding("Y2");
series2.IndependentValueBinding = new System.Windows.Data.Binding("X2");
series2.DependentRangeAxis = YAxis;
series2.IndependentAxis = XAxis;
This code works fine for assigning two series to single Y-Axis, but when two series with different X and Y values are assigned to X-Axis it messes up the first series. It plots both Y1 = {104, 98, 36,....} and Y2 = { 76, 65, 110..} with respect to X2 = {2,4,6..}, instead of plotting X1 with respect to Y1 and X2 with respect to Y2 and having only one X and Y axis.
Please advice me on what needs to be done to assign two different set of values to single X-axis.
Thank you in advance!

问题解决了。这段代码是正确的..这与我的值分配有关（我注意到我在使用 X2 之前清除了 X1 值。但是为了使代码正常工作，所有值 X1、Y1、X2、Y2 应保留，直到图表已创建）..谢谢！
Problem is solved. This code is correct.. There is something to do with my value assignment (I noticed that I was clearing X1 value before using X2. But to make the code work all the values X1, Y1, X2, Y2 should be preserved until the chart is created)..Thank you!
