c# - Binding a DataSet to a MultiColumn MS Chart -

I have a dataset that has many datatables which I want to attach to the chart with several column series. Expect different values ​​related to datatables in datasets; However, when the chart appears, both series display the same values ​​in the Y column, the values ​​from the first tables

Here is a general idea that is my code:

(I have created and named database diffCharts, diffCharts table table 1 and table 2 in both tables is column month and amount )

  chart 1. Series.Add ("table1"); Chart 1 Series ["Table 1"]. XValueMember = "month"; Chart 1 Series ["Table 1"]. YValueMembers = "zodiac"; Chart1.Series.Add ("table2"); Chart 1 Series ["Table 2"]. XValueMember = "month"; Chart 1 Series ["Table 2"]. YValueMembers = "zodiac"; Chart 1.DataSource = Diffhef Card; Chart1.DataBind ();   
 Am I missing something? I have never compromised a dataset with multiple tables in a chart .... How does MS handle it?   
 
 
 I do not think you can do that.  
 You probably need to create a table in the form of a column of X axis (month) as a column, and then for two more column Y values ​​which you want to graph.  
 The datatable class has a merge function, which can actually meet your needs.
