The Radial Gradient fill style option is located in the Fill Panel. This attribute transitions the fill from the specified start color to the specified end color by starting from the center of a selected or created figure(s) and then moving outward in a circular manner and can be accessed in one of the following ways:
Press on the Fill Button located in the Drawing Toolbar.
Press on the Info Button to open the Info Menu.
Then press on the Fill option to open the Fill Panel.
The Fill option must be enabled for a style change to be applied to any currently selected or new figures. Once the Fill Panel has opened, perform a Tap on the On/Off toggle to enable the Fill option.
To change the Fill Type to Radial Gradient:
Press on the Fill Type Button and then press on the Radial Gradient option(if not already selected).
The Fill Panel will expand, as shown below.

To close the Fill Panel, tap on the Hide Sidebar Button located at the bottom of the sidebar panel.
A style change will be seen instantaneously when a figure is selected. If figures have not been selected, the style change will apply to all subsequently created figures.
Working with Radial Gradients
Gradient Handles can be added by tapping on any location underneath the transition bar. Once a new handle has been added, Double Tap on the handle to open the Color Picker and add an additional color. A Touch/Drag gesture combination can be used to move either Gradient Handle to alter the color transition of the fill.
More than one color can be added by setting each individual gradient handle to one of the desired colors. In the example below, three gradient handles are used with these colors: white, blue, and green.
The Reset Button can be used to reset the center point of the radial gradient after it has been moved. In order for this to be seen, you must have the Gradient Locations option enabled. To enable this option, tap on the Overflow Button in the Top Toolbar and then tap on the Handles Submenu.
Then tap on the Gradient Locations option to enable it. When enabled, it will show a blue checkmark.
Once this option is enabled, you will see two additional handles on each selected figure. These may be used to adjust the angle and progression of colors for the radial gradient. Below you will see what a figure looks like when this option has not been enabled and then after it is enabled.
The two handles may be moved to any location within or outside of a figure to change the angle or fill pattern. To do so, press and hold on the handle. Then drag the handle in any desired direction without lifting your finger. Once this option is enabled, you will be able to move the center point to another location within a figure (see below).
After one or both gradient handles has been moved, click on the Reset Button to set the radial gradient handles back to their original location.
Use the Swap Button to reverse the current color slider settings.
