在运行时启用/禁用图表系列 [英] Enable/Disable chart series at runtime

问题描述

我希望有人可以帮助解决MS Chart中的另一个问题。



我在我的图表中动态添加了五个系列，使用以下步骤： for循环：

I hope someone might be able to help with another question re MS Chart.

I have added five series dynamically to my chart, using the following procedure in a for loop:

private void addSeries(string nme, Color clr)
    {
        Chart1.Series.Add(nme);
        Chart1.Series[nme].Name = nme;
        Chart1.Series[nme].ChartType = SeriesChartType.Line;
        Chart1.Series[nme].BorderWidth = 2;
        Chart1.Series[nme].MarkerStyle = MarkerStyle.Circle;
        Chart1.Series[nme].XValueMember = "theDate";
        Chart1.Series[nme].YValueMembers = nme;
        Chart1.Series[nme].Legend = "Legend1";
        Chart1.Series[nme].Color = clr;
    }

现在，我希望能够通过点击按钮启用/禁用每个系列，但是当我尝试我收到一条错误消息，说明在SeriesCollection中找不到系列（永远不会超过循环中的第一个系列）：在SeriesCollection中找不到名为MD的图表元素。我认为调用Series对象的Add方法会将命名的Series添加到SeriesCollection中。如何，我可以确保将动态创建的系列添加到集合中吗？



谢谢

Now, I want to be able to enable/disable each series via a button click, but when I try I''m getting an error message to the effect that the series (never gets past the first one in the loop) cannot be found in the SeriesCollection: "A chart element with the name MD could not be found in the SeriesCollection". I thought that calling the Add method of the Series object would add the named Series to the SeriesCollection. How, can I ensure that dynamically created series are added to the collection?

Thanks


Steve

Use Enabled property for Series(index).
