#MATLAB PLOT LEGEND HOW TO#
The required code isn't pretty, but it does work. The following code shows how to place the legend in the bottom right corner outside of a Matplotlib plot: import matplotlib.pyplot as plt create plot plt.subplot(211) plt.plot( 2, 4, 6, label'First Data') plt.plot( 6, 4, 2, label'Second Data') place legend in top right corner plt.legend(bboxtoanchor (1,0), loc'lower left') show. Plot handles can be concatenated to form an object that legend is happy to accept as input. Plot(x,y), xlabel('x'),ylabel('exp(–1.Craft a custom handle that you feed into the legend. Following example demonstrates the concept − Example Where, m and n are the number of rows and columns of the plot array and p specifies where to put a particular plot.Įach plot created with the subplot command can have its own characteristics. The subplot command is used for creating subplots. When you create an array of plots in the same figure, each of these plots is called a subplot. When you run the file, MATLAB generates the following graph − Generating Sub-Plots The following example shows this − Example You can provide minimum and maximum values for x and y axes using the axis command in the following way − The FaceColor only applies to patches and not to lines. Let us take one more example to plot the function y x 2. x 0:5:100 y x plot(x, y) When you run the file, MATLAB displays the following plot.

Create a script file and type the following code. The axis command allows you to set the axis scales. The reason for which the code provided in the answer to reverse ordering of legend colors in matlab bar plot does not work in your case is because in that case (plot of a bar chart) the object in the legend are patches while in your plot they are lines. Let us plot the simple function y x for the range of values for x from 0 to 100, with an increment of 5. When you run the file, MATLAB generates the following graph − Setting Axis Scales The following table shows the colors and their codes − Code MATLAB provides eight basic color options for drawing graphs. MATLAB generates the following graph − Setting Colors on Graph The following example demonstrates the concept − Example You can draw multiple graphs on the same plot. But again, I wanted to illustrate the point about the legend, which is why I used a simplistic sub-optimal plotting loop. MATLAB generates the following graph − Drawing Multiple Functions on the Same Graph Naturally, plotting in an invisible figure and moving drawnow out of the loop would improve the plotting performance, as well as using the vectorized version of the plot function. You also can create a legend with multiple columns or create a legend for a subset of the plotted data. These examples show how to create a legend and make some common modifications, such as changing the location, setting the font size, and adding a title.
#MATLAB PLOT LEGEND SERIES#
The axis square command generates a square plot. Legends are a useful way to label data series plotted on a graph. The axis equal command allows generating the plot with the same scale factors and the spaces on both axes. The grid on command allows you to put the grid lines on the graph. The title command allows you to put a title on the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis.

MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. MATLAB draws a smoother graph − Adding Title, Labels, Grid Lines and Scaling on the Graph Specify the legend labels as input arguments to the legend function. Please note that as we decrease the increment, the graph becomes smoother.Ĭhange the code file a little, reduce the increment to 5 − Plot two lines and add a legend to the current axes. In this example, we will draw two graphs with the same function, but in second time, we will reduce the value of increment. Let us take one more example to plot the function y = x 2.

Below is my code and picture of the problem. This is even happening with old plots from homework from last year when last year it was giving a correct legend. When you run the file, MATLAB displays the following plot − I already reinstalled Matlab and the problem persists. Let us plot the simple function y = x for the range of values for x from 0 to 100, with an increment of 5.Ĭreate a script file and type the following code − To plot the graph of a function, you need to take the following steps −ĭefine x, by specifying the range of values for the variable x, for which the function is to be plottedįollowing example would demonstrate the concept.
