Create a plot. Add a title with thetitle函数。然后add a subtitle with thesubtitle函数。

plot([0 2],[1 5]) title('Straight Line') subtitle('Slope = 2, y-Intercept = 1')

Create a plot, and add a title to the plot. Defineslopevalueandyinterceptas numeric variables. Definetxtas a combination of literal text and the values ofslopevalueandyinterceptconverted to character vectors. Then, passtxtto thesubtitlefunction to display the subtitle.

plot([0 2],[1 5]) title('Straight Line') slopevalue = 4; yintercept = 1; txt = ['Slope = 'int2str(slopevalue)', y-Intercept = 'int2str(yintercept)]; subtitle(txt)

Create a plot. Add a title with thetitle函数。然后, call thesubtitlefunction, and specify the color using the'Color'name-value pair argument. The color can be a color name, such as'red', or you can specify a custom color using an RGB triplet or hexadecimal color code. In this case, specify'red'.

plot([0 2],[1 5]) title('Straight Line') subtitle('Slope = 2, y-Intercept = 1','Color','red')

Alternatively, call thesubtitlefunction with an output argument to return the text object. Then set the color on the text object. In this case, specify the hexadecimal color code '#DD5500'.

txt = subtitle('Plot of y = 2x + 1'); txt.Color ='#DD5500';

Create a plot, and add a title with thetitle函数。Create a character vector containing TeX markup with custom colors for different words in the subtitle. Then pass the character vector to thesubtitle函数。

plot([0 2],[1 5]) title('Straight Line') txt = ['An {\color{magenta}Attractive '...'\color[rgb]{0 .5 .5}and \color{red}Colorful} Subtitle']; subtitle(txt)

Create a histogram, and add a title with thetitle函数。Create a character vector containing TeX markup with Greek symbols. Then pass the character vector to thesubtitle函数。

histogram(5*randn(1,50)+10) title('Population Data') txt ='{\it\mu} = 10, {\it\sigma} = 5'; subtitle(txt)

Create a histogram, and add a title with thetitle函数。Create a character vector containing TeX markup that displays subscripts and superscripts. Then pass the character vector to thesubtitle函数。

x = -10:0.1:10; y1 = x.^2; y2 = 2*x.^2; plot(x,y1,x,y2); title('Exponential Functions') txt ='y_1 = x^2 and y_2 = 2x^{2 + k}'; subtitle(txt)

To display an italic font for the variables, add the\itmodifier.

txt ='{\ity}_1 = {\itx}^2 and {\ity}_2 = 2{\itx}^{2 + \itk}'; subtitle(txt)

Create a plot, and add a title with thetitle函数。然后create a subtitle containing two lines of text by passing a cell array of character vectors to thesubtitle函数。Each element in the array is a separate line of text.

plot([0 2],[1 5]) title('Straight Line') txt = {'Slope = 2','y-Intercept = 1'}; subtitle(txt)

Create a plot with a title. Then create a subtitle containing an underscore character that the TeX interpreter normally uses for subscripts. Set theInterpreterto'none'when you call thesubtitlefunction, so that the underscore character appears in the subtitle.

plot([0 2],[1 5]) title('Straight Line') subtitle('y_1 = 2x + 1','Interpreter','none')

Create a plot and add a title and a subtitle. Get the current axes, and align the title and subtitle to the left edge of the plot box by setting theTitleHorizontalAlignment属性the axes to'left'.

plot([0 2],[1 5]) title('Straight Line') subtitle('Slope = 2, y-Intercept = 1') ax = gca; ax.TitleHorizontalAlignment ='left';

Center the title and subtitle by setting theTitleHorizontalAlignment属性the axes to 'center'.

ax.TitleHorizontalAlignment ='center';

Create two plots in a tiled chart layout. Then add a title and subtitle to each plot.

t = tiledlayout(1,2);% Left plotax1 = nexttile; plot([0 2],[1 5]) title(ax1,'A Straight Line') subtitle(ax1,'Slope = 2, y-Intercept = 1')% Right plotax2 = nexttile; plot([0 2],[2 8]) title(ax2,'Another Straight Line') subtitle(ax2,'Slope = 3, y-Intercept = 2')
