# Percent Change Charts

Normally the price plot shows the historical prices. Percent change charts are an alternate view that shows the change in the price between each bar as a percentage movement. A percent change chart can be displayed by changing the bar type from the drop down on the tool bar to **Percent Change**.

By default, percent change charts are calculated from the left most point of the chart. This can be changed to a specific bar by right clicking on the chart where you would like the calculation to begin.

Two dashed lines will be displayed to visually indicate where the charts are being calculated (see below).

When combined with the Instrument Overlay, you can compare relative moves between instruments directly on one chart:
