Unlike the plot function, line adds the line to the current axes without deleting other graphics objects or resetting axes properties. For example, 'LineWidth',3 sets the line width to 3 points. Specify name-value pairs after all other input arguments. If you specify the data using name-value pairs, for example line 'XData',x,'YData',y , then you must specify vector data. Specify ax as the first input argument.

Many plotting functions have an input argument called linespec for customizing. Also, the objects returned by these functions typically have properties for controlling these aspects of your plot. The names of the arguments and properties can vary, but the values they accept typically follow a common pattern. Once you are familiar with the pattern, you can use it to modify a wide variety of plots. The following examples use the plot function to demonstrate the overall approach for customizing the appearance of lines. For a complete list of options for a specific plotting function, refer to the documentation for that function. Most line plots display a solid line by default, but you can customize the line with any of the line styles in the following table. For example, create a line plot with a dashed line: plot [0 1 2 3], '--'. Usually, you can specify a marker symbol in addition to the line style. The markers appear at the data points in your chart. For example, create a line plot with a dashed line and circular markers: plot [0 1 2 3], '--o'.

Help Center Help Center. Create a simple line plot and label the axes. Customize the appearance of plotted lines by changing the line color, the line style, and adding markers. Create a two-dimensional line plot using the plot function. Use the figure command to open a new figure window.

Remember, most cliches are cliches because there is a hint of truth in them. MATLAB has robust plotting and graphing capabilities and can generate plots in very few lines of code. Unlike Excel, there is very little in terms of buttons or menus that you have to navigate. Instead with MATLAB, you need to remember a few lines of code but in the end, it is much faster and much more flexible in generating your plots. When you are following along with this chapter, make notes and comments to that script so that you can refer to it later and what you have learned. We will remember everything we learned in Chapter 5 and in addition will learn:. Remember, the philosophy of this book is that diving in and getting your hands dirty metaphorically at least is good for learning! The goal of a tensile test is usually to determine the materials elastic modulus. We call this engineering strain and it is defined as:.

Plot in matlab

MATLAB has tools that enable the user to display data within visual forms such as tables, 2D, or 3D graphs to increase readability for the user. General graphs can be created by the user with the plot command, which can be modified to incorporate colors, symbols, labels, and other aspects of the graph to ensure that the data is able to be read and interpreted by the user. The plot function operates by plotting data assigned to a variable onto a graph. A simple way to graph the first-order line onto a plane is by listing the range of values for both the x and y coordinate which need to be graphed. The following example shows how the user could assign the range for the x- and y-axis, respectively, using vectors.

Use Name,Value pairs to specify the line width, marker size, and marker colors. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. Plot sin x over the default x interval [-5 5]. You have a modified version of this example. Version History Introduced before Ra expand all Rb: Default line color is has changed Now that the SeriesIndex property is available for lines created with the line function, the lines cycle through the same colors and optional line styles that most other plots do. The default value of "auto" uses the same color as the Color property. Specify the interval as a two-element vector of the form [xmin xmax]. Format for duration tick labels, specified as the comma-separated pair consisting of "DurationTickFormat" and a character vector or string containing a duration format. Specify Line Properties. Use only cyan star markers for the third sine curve.

For example, create a line plot with a dashed line and circular markers: plot [0 1 2 3], '--o'. When you zoom in on the chart, fplot replots the data, which can reveal hidden details. If you specify both X and Y , the imaginary part is ignored. MarkerSize — Marker size 6 default positive value. If xvar and yvar both specify multiple variables, the number of variables must be the same. Matrix inputs are supported for Cartesian axes only. If x and y are both vectors with the same length, then line plots a single line. Create a line plot and use the LineSpec option to specify a dashed green line with square markers. The markers appear at the data points in your chart. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix. If the table is a timetable, the specified variable is plotted against the row times of the timetable. Alternatively, you can specify some common colors by name. Alternatively, you can specify some common colors by name. Use this syntax as an alternative to specifying coordinates as matrices.
