2.1 Return value from UDI.onInit()

The return value from UDI.onInit() should be an object, as in the example above, with the following members:

Member	Description
caption	The name to display for your UDI
isOverlay	True/false depending on whether your UDI should be shown in the main chart panel (true) or in its own sub-panel (false)
plots[]	Array describing the types of values which your UDI draws: lines, histograms, bars etc. The array can be empty if your UDI only creates drawings, or event markers, or bar highlights.
settingsFields[]	Array of user-configurable parameters which your UDI wants. This array can be empty if your indicator does not need any configurable settings.
noAlerts	Can be used to turn off the ability for the user to set alerts on any of the UDI's plots. You can also disable this for each individual plot, using its own noAlerts property.
noIOI	Can be used to prevent your UDI participating in the ability to apply one indicator to another indicator.
axis	Overrides the default settings for the value axis, by including any or all of the following properties. Only applicable if the indicator is in its own sub-panel (isOverlay:false).
axis.min	Minimum value for the axis
axis.max	Maximum value for the axis
axis.step	Increment between markers on the axis
axis.noYGrid	Turns off horizontal grid lines in the sub-panel
axis.baseline	Baseline value (which turns a line plot into a filled area either side of the baseline)
