Hi,

I have an interesting issue when generating a bar chart. I am hoping someone can shed some light on it. Code is below:-

Dim NStackedBarChart As New Nevron.Chart.NCartesianChart

NChartTotal.Charts.Clear()
NChartTotal.Charts.Add(chart:=NStackedBarChart)
Dim NBarSeries1 As Nevron.Chart.NBarSeries = NStackedBarChart.Series.Add(type:=Nevron.Chart.SeriesType.Bar)
NBarSeries1.Values.FillFromDataTable(table:=SelectTotal, columnName:="count")

That is literally all the code, SelectTotal returns the database as expected. Attached is the actual chart that gets generated.

Thank you.

Hi John,

In general when you display a stacked bar chart you need to create at least two bar series and you have to set the MultiBarMode property of the series objects to MultiBarMode.Stack.

I guess you want to stack all the values in a single column, but the FillFromDataTable function is not very helpful in this scenario. You can do this with a simple loop that reads the rows from the table and adds a bar series for each row. Please let me know if you need a code example.
