Unfortunately, there's no vertical area chart. The only thing I can think of is rotating the chart image, but it's probably not something you would want to resort to, as this would require to turn off all interactive features of the chart, like tooltips, hilighting, etc. This would only be good for showing the chart image on the form.

sorry, we don't provide this type of chart.  you could implement one using a custom layer, but it would be quite a bit of work.  if you'd like to submit your feature request, you can using this page: http://devcenter.infragistics.com/Protected/RequestFeature.aspx
