XValue in XML?

[User (Legacy)]

I am supplying data to my chart using the XmlDataProvider.  I would like to

use "data driven labels", but the examples all do this by setting the XValue

property via the API.  Is there a way to specify an XValue in XML, or some

other way to make data driven labels work with the XmlDataProvider?

Thanks,

Yes. Use the DataType property prior to doing Data-Binding to tell Chart FX 

which column is to be used for X-Values. For example, if the X-Values come 

in the first column you must do:

chart.DataType[0] = DataType.XValue;

Francisco,

That worked, with one problem.  Every item in the series (i.e. every ROW 

element in the XML) now has a label, except for the first and last.  What do 

I need to do to get labels on the first and last rows in the series (using 

WebForms)?

Thanks,

Dennis

The labels are drawn at certain interval depending on the available space 

and the range.

The labels will also start, by default, at a "nice" position. For example, 

if you have a label every 7 days, the labels will appear every Sunday, so if 

your first point is a Monday, you will get the label a little after that.

You can turn off this behavior by doing:

chart.AxisX.Style &= AxisStyle.AutoFirstLabel;

Also, the last label will only be drawn (in the sample above) on a Sunday. 

To force the last label to show regardless of the other labels:

chart.AxisX.Style |= AxisStyle.ShowEnds;
