Currently, we don't have a way to invert the vertical scale for a SharpChart. We do however have a way to calculate the reciprocal of any dataset and chart that. It's not exactly the same, but it is often good enough. $ONE is a special symbol that always equals 1 which is why this "trick" works. We hope to provide a true way to invert a chart at some point in the future. Most people are interested in the reciprocal of $VIX so we are using that in this example.
Enter $ONE and A Colon Before $VIX
Enter "$ONE:$VIX" in the "Symbol" box above the chart. Click "Update" and your chart will update with the reciprocal.

After you press "Update" the page will refresh and show the reciprocal chart. Here is a live example
