<kettic:ChartSeries Name="Series 1" View=" FullStackedBar">
<kettic:ChartSeriesPoint Value="1.5" Name="Point 1">
<kettic:ChartSeriesPoint Value="4" Name="Point 2">
<kettic:ChartSeriesPoint Value="1" Name="Point 3">
<kettic:ChartSeriesPoint Value="3.5" Name="Point 4">
<kettic:ChartSeriesPoint Value="1" Name="Point 5">
<kettic:ChartSeries Name="Series 2" View=" FullStackedBar">
<kettic:ChartSeriesPoint Value="2" Name="Point 1">
<kettic:ChartSeriesPoint Value="1" Name="Point 2">
<kettic:ChartSeriesPoint Value="5" Name="Point 3">
<kettic:ChartSeriesPoint Value="1" Name="Point 4">
<kettic:ChartSeriesPoint Value="2.5" Name="Point 5">
Now, we provide how to set 100% stacked bar properties using C# code.

KaxChart1.SeriesSet[0].AddPoint(1.5, "Point1");
KaxChart1.SeriesSet[0].AddPoint(4, "Point2");
KaxChart1.SeriesSet[0].AddPoint(1, "Point3");
KaxChart1.SeriesSet[0].AddPoint(3.5, "Point4");
KaxChart1.SeriesSet[0].AddPoint(1, "Point5");

KaxChart1.SeriesSet[1].AddPoint(2, "Point1");
KaxChart1.SeriesSet[1].AddPoint(1, "Point2");
KaxChart1.SeriesSet[1].AddPoint(5, "Point3");
KaxChart1.SeriesSet[1].AddPoint(1, "Point4");
KaxChart1.SeriesSet[1].AddPoint(2.5, "Point5");
Of course, you are allowed to customize the bar color with the attribute ChartSeries.Appearance. FillStyle-MainColor. With different color in each data series group, users can separate the data more easily, so that they can make a better data trend analysis.
