I am trying to build a chart that displays the status of items over time. The attached image shows a timeline, and the historical status of items over time. Is there a simple way to produce this type of output using a stacked bar or guage? I dont see any samples that demo this type of chart.

I have a DataTable that I am trying to filter to display multiple pie charts from one set. I am able to filter my data using a DataView but once the data is assigned to the Chart, I want to remove the filtered column from the bound fields. I want to do this because the filtered data is being used as labels when I want other fields from the dataview. In my sample code below. I want to remove the "REGION" column so that my labels are pulled from the "TYPE" column. If I try to do this by removing the REGION from usage, the chart displays no data. How can I do this? Is there a completely different approach to doing this in the chart? I know i can do this my manually building a new Data Table that doesnt contain the "REGION" column, but it looks like the chart should be able to exclude the column for me.
