Overview
The Panes feature of Chart FX for iOS allows the developer to display multiple panes of data in a single chart window. This data analysis feature allows developers to separate or combine several series allowing for improved analysis experience. This could be used for many applications, the most obvious being to improve readability by simplifying the display of a chart.
In the chart above, three series are each assigned to an individual pane. As you can see, each pane has several attributes unique to that pane instance, such as the InsideBackObject, InsideColor, Proportion, Separation and Title. Also observe how each of the panes have an independent axis.
The first indexed pane of the collection is referred to the main pane of the chart. It can be accessed by the mainPane property of the Chart class.

Parameters

ChartFX.h
background
Gets or sets an ImageBackground or GradientBackground object for a pane.
Discussion
Each pane present in a chart may have a unique ImageBackground or GradientBackground object configured as the background.

ChartFX.h
proportion
Gets or sets a value indicating the proportional size of the selected pane.
Discussion
This property accepts an integer that specifies the "proportional" size of a selected pane. For Example, If you set this property to a value of 2, that pane's height would be twice the size of any default pane's height. The default pane size will depend on the number of panes visible in the chart as well as the dimensions of the chart object itself.

ChartFX.h
separation
Gets or sets a value indicating the space between panes.
Discussion
This property is useful when multiple panes are configured and you need to create space for readability.
Declared In
ChartFX.h
title
Gets the Title object for a selected pane.
Discussion
This property returns a Title object. By accessing the title class members you will be able to control attributes such as: Alignment, Color, Font, Text, etc.
Each pane may only have one title.
The separation property may be used to control the space between panes. This may be useful to developers trying a change the font for a pane's title.
Declared In
ChartFX.h
visible
Gets or sets a value indicating if the Pane object should be shown or not.
Discussion
Hiding a Pane object will hide all the series associated with that pane, not only from the chart area but also from the Legend and the DataGrid. The hidden series objects will remain accessible but invisible.
Hiding a Pane object does not destroy or lose previous settings assigned by other properties.
