You can plot more than one symbol in the same Chart Analysis window. By default, each additional symbol will plot underneath the other in a separate subgraph. You will begin with a chart analysis window that already has a symbol plotted (base price data) then add a second symbol to the Chart Analysis window without replacing the first symbol.
You cannot combine a symbol using a tick-based data interval with any other type of data interval (for example, you cannot plot one symbol as a 1-tick chart and the other as a 5-minute chart). You can not combine Point & Figure charts with other data intervals.
