Just like with Level II and other windows, you can specify the symbol to monitor, the source of the data and Start or Stop the data flow. Several other panels, such as Level 1/Quote information, and the tops bids/asks can also be shown. The View tab of the ribbon menu controls which panels are shown, the font size and the color scheme of the window.

 

The Depth Chart itself displays the book in cumulative form - that is, the chart's Y value at any point is the sum of all bids (or asks) from the best bid (ask) to the price value on the X axis.
