printToFigure
Description
Examples
Print Spectrum Analyzer Scope Display to MATLAB Figure
Use the printToFigure
function to print the spectrumAnalyzer
object display window to a new MATLAB® figure.
Generate a chirp signal and use the spectrumAnalyzer
object to display the spectrum of the chirp. This plot shows the default color and style settings of the spectrumAnalyzer
object.
chirp = dsp.Chirp(SweepDirection="Bidirectional", ... TargetFrequency=2000, ... InitialFrequency=0,... TargetTime=400, ... SweepTime=400, ... SamplesPerFrame=1024, ... SampleRate=4000); scope = spectrumAnalyzer(AveragingMethod="exponential",... ForgettingFactor=0,SampleRate=4000); scope(chirp());
Change the background color and the axes color of the plot to "white"
. Set the font color and line color to "black"
.
scope.BackgroundColor = "white"; scope.AxesColor = "white"; scope.FontColor = "black"; scope.LineColor = "black"; show(scope) release(scope)
Print the display of the chirp spectrum to a new MATLAB figure. The function returns a handle to the figure.
scopeFig = printToFigure(scope);
The handle to the figure scopeFig
lets you modify the appearance and the behavior of the figure window.
Specify a figure name and change the size of the figure to 400-by-250 pixels.
scopeFig.Name="Spectrum of Chirp Signal"; scopeFig.NumberTitle="off"; scopeFig.Position=[1 1 400 250];
When printing to figure, you can make the figure invisible by setting the Visible
argument to false
.
scopeFig = printToFigure(scope,Visible=false);
Print Array Plot Scope Display to MATLAB Figure
Use the printToFigure
function to print the dsp.ArrayPlot
object display window to a new MATLAB® figure.
Create a dsp.ArrayPlot
object.
scope=dsp.ArrayPlot;
Set ArrayPlot
properties to display a Gaussian distribution.
scope.YLimits = [-0.1 1.1]; scope.XOffset = -2.5; scope.SampleIncrement = 0.1; scope.Title = "Gaussian distribution"; scope.XLabel = "X"; scope.YLabel = "f(X)";
Plot the Gaussian distribution.
scope(exp(-(-2.5:.1:2.5) .* (-2.5:.1:2.5))');
Change the background color and the axes color of the plot to "white"
. Set the font color to "black"
and the line color to "blue"
.
scope.BackgroundColor = "white"; scope.AxesColor = "white"; scope.FontColor = "black"; scope.LineColor = "blue"; show(scope) release(scope)
Print the display of the Gaussian distribution to a new MATLAB figure. The function returns a handle to the figure.
scopeFig = printToFigure(scope);
The handle to the figure scopeFig
lets you modify the appearance and the behavior of the figure window.
Specify a figure name and change the size of the figure to 400-by-250 pixels.
scopeFig.Name="Gaussian Distribution"; scopeFig.NumberTitle="off"; scopeFig.Position=[1 1 400 250];
When printing to figure, you can make the figure invisible by setting the Visible
argument to false
.
scopeFig = printToFigure(scope,Visible=false);
Print Time Scope Display to MATLAB Figure
Use the printToFigure
function to print the timescope
object display window to a new MATLAB® figure.
View a sine wave on the time scope. This plot shows the default color and style settings of the timescope
object.
f = 100; fs = 1000; swv = sin(2.*pi.*f.*(0:1/fs:1-1/fs)).'; scope = timescope(SampleRate=fs,... TimeSpanSource="property", ... TimeSpan=1); scope(swv);
Change the background color and the axes color of the plot to "white"
. Set the font color to "black"
and the line color to "blue"
.
scope.BackgroundColor = "white"; scope.AxesColor = "white"; scope.FontColor = "black"; scope.LineColor = "blue"; show(scope) release(scope)
Print the display of the sine wave to a new MATLAB figure. The function returns a handle to the figure.
scopeFig = printToFigure(scope);
The handle to the figure scopeFig
lets you modify the appearance and the behavior of the figure window.
Specify a figure name and change the size of the figure to 400-by-250 pixels.
scopeFig.Name="Sine Wave Signal"; scopeFig.NumberTitle="off"; scopeFig.Position=[1 1 400 250];
When printing to figure, you can make the figure invisible by setting the Visible
argument to false
.
scopeFig = printToFigure(scope,Visible=false);
Print Dynamic Filter Visualizer Display to MATLAB Figure
Use the printToFigure
function to print the dsp.DynamicFilterVisualizer
object display window to a new MATLAB® figure.
Create a dsp.DynamicFilterVisualizer
object.
dfv = dsp.DynamicFilterVisualizer(YLimits=[-120 10]);
Design FIR filter with varying cutoff frequencies ranging from 0.1 to 0.5. Plot the magnitude response of the filter using the Dynamic Filter Visualizer.
for k = 0.1:0.001:0.5 b = fir1(90, k); dfv(b,1); end
Change the background color and the axes color of the plot to "white"
. Set the font color to "black"
and the line color to "blue"
.
dfv.BackgroundColor = "white"; dfv.AxesColor = "white"; dfv.FontColor = "black"; dfv.LineColor = "blue"; show(dfv) release(dfv)
Print the display of the magnitude response to a new MATLAB figure. The function returns a handle to the figure.
scopeFig = printToFigure(dfv);
The handle to the figure scopeFig
lets you modify the appearance and the behavior of the figure window.
Specify a figure name and change the size of the figure to 400-by-250 pixels.
scopeFig.Name="Magnitude Response of FIR Filter"; scopeFig.NumberTitle="off"; scopeFig.Position=[1 1 400 250];
When printing to figure, you can make the figure invisible by setting the Visible
argument to false
.
scopeFig = printToFigure(dfv,Visible=false);
