zedgraph。如何绘制散点图，但每个点的颜色不同 [英] zedgraph. How to draw scatter plots but with different color for each dot

问题描述

我希望函数AddLine

I wish the function AddLine

LineItem myCurve = myPane1.AddCurve("", x_axis_array, Y_AxixArray, Color.Black, SymbolType.Diamond);

可以选择：

could have an option of:

LineItem myCurve = myPane1.AddCurve("", x_axis_array, Y_AxixArray,COLOR_ARRAY[],  SymbolType.Diamond);

希望你得到了我想做的事。



非常感谢任何答案。！

Hopefully you get what I want to do.

Any answer is highly appreciated.!

   Color currentColor = myColorArr[0];<br />
               //int startidx = 0;<br />
               for (int i = 0; i < datacount; i++)<br />
               {<br />
                   if (currentColor == myColorArr[i])<br />
                   {<br />
                       list_x.Add(list_x[i]);<br />
                       list_y.Add(list_y[i]); <br />
                   }<br />
                   else<br />
                   {<br />
                       list_x.Add(list_x[i]);<br />
                       list_y.Add(list_y[i]);<br />
<br />
                       LineItem myCurve1 = myPane1.AddCurve("", list_x.ToArray(), list_y.ToArray(), myColorArr[i-1],SymbolType.Diamond);<br />
                       myCurve1.Line.IsVisible = true; // was false for scatter plot<br />
                       myCurve1.Symbol.Fill = new Fill(myColorArr[i - 1]);<br />
                       list_x.Clear();<br />
                       list_y.Clear();<br />
                       currentColor = myColorArr[i];<br />
                       list_x.Add(list_x[i]);<br />
                       list_y.Add(list_y[i]); <br />
                   }<br />
               }

感谢您的帮助！

Thanks for your help!

（我假设您正在讨论开源 zedgraph [ ^ ]）



您可以下载代码并自行进行修改;如果有效，请将更改提交给zedgraph项目。



除此之外，我不知道zedgraph。

(I assume you are talking about the opensource zedgraph[^])

You could download the code and do the modification yourself; and if that works, submit the changes to the zedgraph project.

Other than that, I don't know zedgraph.

无需对相同颜色的点进行分组，请参见下面的示例

No need to group the point with same color,see example as below

GraphPane gp=ZedGraphControl.GraphPane;
PointPairList pointXY=new PointPairList();
pointXY.Add(1,1);
LineItem point=gp.AddCurve("Label",pointXY,YourColor,SymbolType.Circle);

然后将绘制圆形符号，您可以用目标颜色填充圆形符号

then a circle symbol will be plotted, you can fill the circle symbol with your target color
