It is possible to generate the pie chart (pie) by comparing different columns of a DataTable?

I mean, I have one DataTable with 2 columns of values and wanted to create a pie chart for each row of the DataTable, thus comparing the two values.

DataTable:

Descricao | Val1 | Val2
xxxxxxxx  | 9999 | 8888
yyyyyyyy  | 1111 | 2222

I’m using the Microsoft Chart Control, which is native to . net

  • Yes, it is possible. The idea is to draw the graph completely from scratch? Or use something like .net charting?

There is. The DataTable Microsoft has the facility to create objects of the type DataView.

In other words, they are filters or "SELECTS" that you can do inside a Datatable. You can create 2 DataView for each type of Chart you want to create and, for each Chart, you arrow the DataSouce of them for each DataView servant.

The advantage is that if you add or modify information in the Datatable, automatically this modification is reflected in all existing Dataviews and consequently in your Dataviews (maybe you need to make a rebind, but nothing too complicated).
