Histogram chart custom height of columns

this.ultraChart1.Axis.X.Labels.ItemFormatString = "<MY_VALUE>";
Hashtable MyLabelHashTable = new Hashtable();
MyLabelHashTable.Add("MY_VALUE", new MyLabelRenderer());
this.ultraChart1.LabelHash = MyLabelHashTable;

Hello, thanks but I think I will use workaround with column chart and just move labels.

I wanted to ask other thing. Is there a way to combine column chart and line chart in the way that I can provide data for each chart separately. So for Line chart for example I want to show 20 points and for column chart only 9 columns.

There is a code that I want to use but I see empty screen:

foreach (Primitive p in e.SceneGraph)

The X axis I want to use only for column chart labels

Thanks in advance
