Microsoft Chart Tool 3.5 guide

To display a chart similar to the one below

 

 

Three easy steps to do the chart:

1. Create a DataTable with columns equal to number of bars needed for each week and a column for week itself. Populate table data.
2. Create a chart with series based on the datatable columns as below

for (int i = 1; i < chartData.Columns.Count; i++)

        {

            if (isFirstColumn)

            {

                Chart1.Series[0].XValueMember = chartData.Columns[0].ToString();

                Chart1.Series[0].YValueMembers = chartData.Columns[i].ToString();

                isFirstColumn = false;

            }

            else

            {

                Chart1.Series.Add(Convert.ToString(i));

                Chart1.Series[Convert.ToString(i)].XValueMember = chartData.Columns[0].ToString();

                Chart1.Series[Convert.ToString(i)].YValueMembers = chartData.Columns[i].ToString();

            }

        }

3. Your are done, just bind the chart with the datatable
