I am using a chart control with a range bar graph to basically make a gantt chart for lots of people and lots of projects, say about 1000 total series.

The issue that I am running in to is that once I have all my data added to the chart, which takes some time but that is to be expected, and I go to scroll down on my graph it freezes the whole application and takes a while before it unfreezes and scrolls down.

Is there any way to improve the performance of this? I tried adding the graph to a panel and growing the graph size dynamically and then scrolling down from the panel but that cause a whole plethora of other issues.

Any tips for speeding this up? I don't think it is my code as it has already finished running when this issue happens.

Thanks.
