Get tiled chart layout for chart container subclass

Syntax

tcl = getLayout(obj)

Description

[tcl](#mw%5F59161bb2-35ee-41eb-8e76-e2663f648a1b) = getLayout([obj](#mw%5Fe3ac8a91-33e2-47ed-83ee-2bddf4382620)) returns the tiled chart layout for a chart object that inherits from thematlab.graphics.chartcontainer.ChartContainer base class.

Input Arguments

expand all

Object of the class that inherits from thematlab.graphics.chartcontainer.ChartContainer base class.

Output Arguments

expand all

TiledChartLayout object. Use tcl when you are developing a chart that contains a polar plot, a geographic plot, or a tiling of multiple plots. You can configure certain aspects of the layout, such as the number of tiles, the location of each axes object, and the spacing between the tiles.

Define a class called CartPolarPlot that plots data in Cartesian and polar coordinates.

To define the class, create a file called CartPolarPlot.m that contains the following class definition with these features:

• Three public properties: XData and YData to store the coordinate data, and LineColor to control the color of the lines
• Four private properties that store the two lines and axes objects
• A setup method that configures the layout, creates the axes, and initializes the two Line objects
• An update method that updates the Line objects when the user changes the value of one or more public properties

classdef CartPolarPlot < matlab.graphics.chartcontainer.ChartContainer properties XData (1,:) double = NaN YData (1,:) double = NaN LineColor (1,3) double {mustBeGreaterThanOrEqual(LineColor,0),... mustBeLessThanOrEqual(LineColor,1)} = [.5 0 1] end properties(Access = private,Transient,NonCopyable) CartesianLine (1,1) matlab.graphics.chart.primitive.Line PolarLine (1,1) matlab.graphics.chart.primitive.Line CartesianAx (1,1) matlab.graphics.axis.Axes PolarAx (1,1) matlab.graphics.axis.PolarAxes end

methods(Access = protected)
    function setup(obj)
        % Get the layout and create the axes
        tcl = getLayout(obj);
        tcl.GridSize = [1 2];
        obj.CartesianAx = axes(tcl);
        obj.PolarAx = polaraxes(tcl);
        
        % Move the polar axes to the second tile
        obj.PolarAx.Layout.Tile = 2;
        
        % Create the Cartesian and polar lines
        obj.CartesianLine = plot(obj.CartesianAx,NaN,NaN);
        obj.PolarLine = polarplot(obj.PolarAx,NaN,NaN);
    end
    function update(obj)
        % Update Cartesian line
        obj.CartesianLine.XData = obj.XData;
        obj.CartesianLine.YData = obj.YData;
        obj.CartesianLine.Color = obj.LineColor;
        
        % Update polar line
        obj.PolarLine.Color = obj.LineColor;
        obj.PolarLine.ThetaData = obj.XData;
        obj.PolarLine.RData = obj.YData;
    end
end

end

Next, create a set of _x_- and _y_-coordinates. Then plot the coordinates by calling the CartPolarPlot constructor method with the 'XData' and 'YData' name-value pair arguments.

x = 0:0.01:2pi; y = sin(2x).cos(2x); CartPolarPlot('XData',x,'YData',y);
