There are a couple ways to display a non-linear chart such as Tick, Volume, Range, Renko, Point and Figure, and Reversal.
The first method is to bring up your Chart Settings by clicking on the Bar Size chooser on the top toolbar in the default layout then go to the Custom tab. Here you are able to select the Bar Size drop down menu for your desired non-linear bar size and then you are able to set the interval below.
The second method is to add the custom bar sizes to the Favourites list (screenshot above). You will then be able to right-click the chart background and select one of the quick bar size options.
In the screenshot below, Tick (10) was added to the Favourites list so the option of Tick (10) shows up on the right click context menu > Bar Size:

Another method is to double-click on the chart background, then select the Bar Settings tab.
