To create a new script, select the icon in the top left corner to begin. The syntax follows the format below:. Having too few points will result in graphs that are inaccurate. However, if linspace 0,10, is used to generate points instead of 10, the figure below is produced. Declare an exponential function using the following expression. The function has the following syntax, where Y is plotted with the corresponding X values. A new window will open with the figure.

Anyone — from beginners hoping to create their first plot to advanced users looking for a refresher — can use these plotting techniques and functions. This video covers making and plotting data, and it shows different plot screen positioning options and plot appearance options. The video first walks through the process of creating sets of numbers that are ready to be inputted into a plot. It illustrates how you can quickly make sample data for a plot using commands like randn and linspace. Then, the video covers the plot function itself, and it shows how using the plot function instantly creates a plot figure window containing the data. View more related videos.

Help Center Help Center. To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Use this syntax as an alternative to specifying coordinates as matrices. You can specify LineSpec for some x - y pairs and omit it for others. For example, plot X1,Y1,"o",X2,Y2 specifies markers for the first x - y pair but not for the second pair.

A picture is worth a thousand words, particularly visual representation of data in engineering is very useful. Students are encouraged to study that section; what follows is a brief summary of the main plotting features. Probably the most common method for creating a plot is by issuing plot x, y statement where function y is plotted against x. This opens a menu from which we choose plot x,y. See the figure below.

Syntax plot Y plot X1,Y1, Description plot Y plots the columns of Y versus their index if Y is a real number. If Y is complex, plot Y is equivalent to plot real Y ,imag Y. In all other uses of plot , the imaginary component is ignored. 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.

Create and plot a directed graph. Example: plot [0 1],[2 3],"LineWidth",2. Add a second plot that uses a dashed, red line with circle markers. Places the graph nodes on a circle centered at the origin with radius 1. ZData — z-coordinate of nodes vector. Plot the graph, labeling the edges with their weights, and making the width of the edges proportional to their weights. The video first walks through the process of creating sets of numbers that are ready to be inputted into a plot. The TickLabelFormat property of the datetime ruler stores the format. For example, change the line to a red dotted line with point markers.

Edge labels, specified as the comma-separated pair consisting of 'EdgeLabel' and a numeric vector, cell array of character vectors, or string array. Example: '--or' uses red circle node markers and red dashed lines as edges. Up Next:. Modify Lines After Creation. References [1] Fruchterman, T. MarkerSize — Node marker size positive value vector. This table describes the most common situations. Smaller graphs have a marker size of 4. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes. You can also call the colororder function to change the color order for all the axes in the figure. Plot a circle centered at the point 4,3 with a radius equal to 2. Therefore, the color codes " FF" , " ff" , " F80" , and " f80" are equivalent. The length of EdgeLabel must be equal to the number of edges in the graph. To access individual properties, use dot notation.
