Matlab plot function

The plot function in Matlab is used to create a graphical representation of some data, matlab plot function. It is often very easy to "see" a trend in data when plotted, and very difficult when just looking at the raw numbers. The plot function usually takes two arguments but can take matlab plot function. The first is the X values of the points to plot, and the second is the Y value of the points to plot.

Each specification can include characters for the line color, style, and marker. Notice that the titles and labels that you defined for the first plot are no longer in the current figure window. To add plots to an existing figure, use hold on. Until you use hold off or close the window, all plots appear in the current figure window.

You do not need to specify all three characteristics line style, marker, and color.

For example, '-r' plots a red line. Use this option after any of the input argument combinations in the previous syntaxes. For example, 'LineWidth',2 specifies a line width of 2 points. Specify the axes as the first input argument.

To plot multiple data sets, specify multiple variables for xvar , yvar , or both. Do you want to open this example with your edits? Off-Canvas Navigation Menu Toggle. Example: "DurationTickFormat","hh:mm:ss. After plotting the first function, add successive functions by using the hold on command. You do not need to specify all three characteristics line style, marker, and color. Graphical capabilities of MATLAB include plotting tools, standard plotting functions, graphic manipulation and data exploration tools, and tools for printing and exporting graphics to standard formats. Display these labels by using the XTickLabel property. As an alternative to plotting expressions symbolically, you can substitute symbolic variables with numeric values by using subs. MarkerSize — Marker size 6 default positive value. If you do not specify an axes object, then fplot uses the current axes gca. If the table is a timetable, the specified variable is plotted against the row times of the timetable.

Range of values of parameter t , specified as a vector of two numbers. Single Argument to Plot If you have a single array that you wish to plot, and don't really care about the X axis, you just want to see the values plotted in the Y axis, you can pass a single array to the plot function. Example: fplot x sin x plots sin x over the default interval, [-5, 5]. Example: plot tbl,"x",["y1","y2"] specifies the table variables named y1 and y2 for the y -coordinates. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 categorical datetime duration. Version History Introduced before Ra expand all Rb: Plots created with tables preserve special characters in axis and legend labels When you pass a table and one or more variable names to the plot function, the axis and legend labels now display any special characters that are included in the table variable names, such as underscores. The line width cannot be thinner than the width of a pixel. Line style, specified as one of the options listed in this table. Example: "DurationTickFormat","d" displays duration values in terms of fixed-length days. Use array operators instead of matrix operators for the best performance. Fix this issue by increasing MeshDensity to 39 in the second subplot. Do you want to open this example with your edits? If you do not specify an axes object, then fplot uses the current axes gca. Plot tan x over the default range [-5 5].
