Display Data with Twoy-Axes

Use theyyaxisfunction to create a plot with twoy-axes. For example, you can use twoy-axes to plot two lines on different scales.

创建一个n axes object, and activate the lefty-axis by callingyyaxis left. Then plot a sine wave.

figure yyaxisleftx = linspace(0,10); y = sin(3*x); plot(x,y)

Activate the righty-axis by callingyyaxis right. Then plot an amplified sine wave.

yyaxisrighty2 = sin(3*x).*exp(0.5*x); plot(x,y2)

Display Data with Multiplex-Axes andy-Axes

Since R2019b

To plot two sets of data with separatex- andy-axes, create two separate axes objects in a tiled chart layout. Within one of the axes objects, move thex-axis to the top of the plot box, and move they-axis to the right side of the plot box.

For example, you can create two plots that have differentx- andy-axis limits.

First, create two sets ofx- andy-coordinates.

x1 = 0:0.1:40; y1 = 4.*cos(x1)./(x1+2); x2 = 1:0.2:20; y2 = x2.^2./x2.^3;

创建一个tiled chart layout and an axes object. Then plot into the axes:

t = tiledlayout(1,1); ax1 = axes(t); plot(ax1,x1,y1,'-r') ax1.XColor ='r'; ax1.YColor ='r';

创建一个second axes object and plot the second set of data in black rather than red. Then, set properties on the second axes object to move thex-axis andy-axis, and to ensure that neither plot obscures the other.

ax2 = axes(t); plot(ax2,x2,y2,'-k') ax2.XAxisLocation ='top'; ax2.YAxisLocation ='right'; ax2.Color ='none'; ax1.Box ='off'; ax2.Box ='off';

Plot Data on Discontinuousx-Axis

Since R2019b

You can use a tiled chart layout to give the appearance of a plot that is broken into intervals along one axis. For example, you might want to exclude one section of thex-axis to focus on other regions of interest.

Create coordinate vectorsxandy.

x = 0:0.1:60; y = 4.*cos(x)./(x+2);

创建一个tiled chart layout containing two tiles, and place an axes object across both tiles. In the final presentation, this axes object will appear in the background, behind two other axes objects. A section of itsx-axis will be visible to give the appearance of one longx-axis.

figure t = tiledlayout(1,2,'TileSpacing','compact'); bgAx = axes(t,'XTick',[],'YTick',[],'Box','off'); bgAx.Layout.TileSpan = [1 2];

创建一个n axes object in front ofbgAxin the first tile. Plotxandy, and set thex-axis limits to the first interval:

ax1 = axes(t); plot(ax1,x,y) xline(ax1,15,':'); ax1.Box ='off'; xlim(ax1,[0 15]) xlabel(ax1,'First Interval')

Repeat the process to create another axes object and plot for the second interval. The axes appears in the first tile by default. Move it to the second tile by setting theLayout.Tileproperty of the axes to2. Then, link the axes so that the limits of bothy-axes match.

% Create second plotax2 = axes(t); ax2.Layout.Tile = 2; plot(ax2,x,y) xline(ax2,45,':'); ax2.YAxis.Visible ='off'; ax2.Box ='off'; xlim(ax2,[45 60]) xlabel(ax2,'Second Interval')% Link the axeslinkaxes([ax1 ax2],'y')

To add a title, pass the tiled chart layout to thetitlefunction.

title(t,'Attenuated Cosine Function')

Display Two Sets of Data with Separate Colorbars

Since R2020b

一个坐标轴对象可以容纳only one colorbar. To create a visualization with multiple colorbars, stack multiple axes objects in a tiled chart layout. Make only one of the axes visible, but display a colorbar next to each of them in an outer tile of the layout.

Create the coordinate vectors, size data, and color data for two bubble charts.

x = 1:15; n = 70 * randn(1,15) + 50; y1 = n + x.^2; y2 = n - linspace(1,225,15); sz1 = rand(1,15); sz2 = rand(1,15); c = linspace(1,10,15);

Stack two axes objects, each containing a bubble chart, in a tiled chart layout.

% create first bubble chart with winter colormapt = tiledlayout(1,1); ax1 = axes(t); bubblechart(ax1,x,y1,sz1,c) colormap(ax1,'winter')秋天%创建第二个泡泡图colormapax2 = axes(t); bubblechart(ax2,x,y2,sz2,c) colormap(ax2,“秋天”) ax2.Visible ='off';% link the limits of axeslinkaxes(t.Children)

Display a colorbar with a label for each axes object in the east tile of the layout. The layout arranges the colorbars and keeps them aligned.

cb1 = colorbar(ax1); cb1.Layout.Tile ='east'; cb1.Label.String ='Time (s)'; cb2 = colorbar(ax2); cb2.Layout.Tile ='east'; cb2.Label.String ='Concentration (M)';
