I apologize for this second response, I forgot to answer your other questions in my previous post.
Is there a built-in way to zoom out of the chart?
Unfortunately there is no out-of-the-box feature that lest you do this. We usually suggest that you place a Button ("Zoom Out") somewhere on top of (or by) the chart and in the Click handler of the button set the Zoom of the chart to (1, 1).
Also is there way built-in to pan over the chart with the mouse
Currently you can only pan with the Slider or if you set the PanOffset property through code. Right now there is no out-of-the-box feature that lets you grab the chart area and pan the chart.
Let me know if you have any other inquiries.
