See the text String property for a list of symbols and how to display them. set( findobj(gca,'Type','line','Color',).Īxis, bar, grid, hold, legend, line, LineSpec, loglog, plot3, plotyy, semilogx, semilogy, subplot, title, xlabel, xlim, ylabel, ylim, zlabel, zlim, stem.In the same statement, set the LineWidth property to 2 points. Now change the line color to red by first finding the handle of the line object created by plot and then setting its Color property. For example, using the graph from the previous example, add an x- and y-axis label: MATLAB enables you to add axis labels and titles. So you will basically type in the name of the function first and then type in the interval.
The proper syntax for fplot is: fplot (name of function, interval). To plot an anonymous function, you must use fplot even if your function is not named 'f'. This problem gives an introduction to the built-in MATLAB function. On the next line you will write a statement to plot the function.

Now add axis labels and annotate the point -pi/4, sin(-pi/4).Īdding Titles, Axis Labels, and Annotations Then, the data to plot the graph and code to find the peaks of the obtained through. For example, this plot of the sine function relabels the x-axis with more meaningful values: You can adjust the axis tick-mark locations and the labels appearing at each tick. Specifying Tick-Mark Location and Labeling
MarkerSize - Specifies the size of the marker in units of points. MarkerFaceColor - Specifies the color of the face of filled markers. MarkerEdgeColor - Specifies the color of the marker or the edge color for filled markers (circle, square, diamond, pentagram, hexagram, and the four triangles). LineWidth - Specifies the width (in points) of the line. You can also specify other line characteristics using graphics properties (see line for a description of these properties): See LineSpec for more information on specifying line styles and colors. See Creating Line Plots and Annotating Graphs for more information on plotting. In the following sequence of commands, MATLAB continues to cycle through the colors defined by the axes ColorOrder property (see above). The all option to the hold command prevents the ColorOrder and LineStyleOrder from being reset in subsequent plot commands. Prevent Resetting of Color and Styles with hold all Sets the default ColorOrder to use only the color black and sets the LineStyleOrder to use solid, dash-dot, dash-dash, and dotted line styles. If you want changes you make to these properties to persist, then you must define these changes as default values. The default LineStyleOrder property has a single entry (a solid line with no marker).īy default, MATLAB resets the ColorOrder and LineStyleOrder properties each time you call plot. After cycling through all the colors defined by ColorOrder, plot then cycles through the line styles defined in the axes LineStyleOrder property. If you do not specify a color when plotting more than one line, plot automatically cycles through the colors in the order specified by the current axes ColorOrder property. Returns the handles to line objects instead of lineseries objects. Returns a column vector of handles to lineseries graphics objects, one handle per line. Plots into the axes with handle axes_handle instead of the current axes ( gca). The basic syntax of the function call is shown below. (See the "Examples" section for examples.) The plot command also happens to be one of the easiest functions to learn how to use. Sets properties to the specified property values for all lineseries graphics objects created by plot. See LineSpec for a list of line style, marker, and color specifiers. You can mix Xn,Yn,LineSpec triples with Xn,Yn pairs: plot(X1,Y1,X2,Y2,LineSpec,X3,Y3). Plots all lines defined by the Xn,Yn,LineSpec triples, where LineSpec is a line specification that determines line type, marker symbol, and color of the plotted lines. If only Xn or Yn is a matrix, the vector is plotted versus the rows or columns of the matrix, depending on whether the vector's row or column dimension matches the matrix. Plots all lines defined by Xn versus Yn pairs. In all other uses of plot, the imaginary component is ignored. If Y is complex, plot(Y) is equivalent to plot(real(Y),imag(Y)). Plots the columns of Y versus their index if Y is a real number. Plot (MATLAB Functions) MATLAB Function Reference
