Help Center Help Center. If either x or y , or both are matrices, then line draws multiple lines. 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.

Help Center Help Center. Line plots are a useful way to compare sets of data or track changes over time. You can plot the data in a 2-D or 3-D view using either a linear or a logarithmic scale. Also, you can plot expressions or functions over specific intervals. Create a 2-D line plot and specify the line style, line color, and marker type. Add markers to a line plot to distinguish multiple lines or to highlight particular data points. Create a plot with confidence bounds using the fill function to draw the confidence bounds and the plot function to draw the data points. Create plots with data that represents dates and times, using appropriate units and customized labels. Read dates and times from data files and display them in plots. Create a chart with y -axes on both the left and right sides. This example shows how to combine a line chart and a bar chart using two different y -axes.

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.

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:.

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. This notation will generate a graph with a line running from the point 5,11 to 10, This is an easy way to generate a linear graph but most applications within scripts will be more involved than this. The above technique can be modified to make one variable dependent on the other.

It simply adds the line to the current axes without deleting other graphics objects or resetting axes properties. Many plotting functions have a single argument for specifying the color, the line style, and the marker. Read weather. The x -coordinates range from 1 to the number of rows in Y. For example, change the line to a red dotted line with point markers. Create a line plot and use the LineSpec option to specify a dashed green line with square markers. ErrorBar Properties. Until you use hold off or close the window, all plots appear in the current figure window. Example: line x,y,'Color',' D9A2E9'. LineWidth — Line width 0. Plot Multiple Lines. Use pl to query or modify properties of the line after it is created. Main Content. Search MathWorks. Before Ra, use commas to separate each name and value, and enclose Name in quotes.

To access individual properties, use dot notation. Use the linspace function to define x as a vector of values between 0 and Example: "--or" is a red dashed line with circle markers. Open Live Script. Create x and y as vectors. Notice that the axis labels match the variable names. This example shows how to combine a line chart and a bar chart using two different y -axes. Up Next:. Therefore, the color codes " FF" , " ff" , " F80" , and " f80" are equivalent. Unlike the plot function, the line function does not call newplot before plotting and does not respect the value of the NextPlot property for the figure or axes. The interpretation of the first coordinate depends on the type of axes. In addition, you can display up to nine fractional second digits by appending up to nine S characters. If one of x or y is a vector and the other is a matrix, then line plots multiple lines. If you use the fplot funx,funy syntax or a variation of this syntax, then fplot returns ParameterizedFunctionLine objects. Add blue, circle markers.
