![]() ![]() ![]() ![]() You will see that I need to create an extra variable ax. Handles, labels = ax.get_legend_handles_labels() Thus, I need a legend, however, taking a look at the following example below( from the official site): ax = subplot(1,1,1) However, it is unclear what data is being plotted where (I'm trying to plot the data of some sorting algorithms, length against time taken, and I'd like to make sure people know which line is which). Pass the handle object as the first positional argument. This ideally generates a graph like the one below: Create a Triangle handle object and call its area method with the engine. Total_lengths, sort_times_merge_i, 'p-', )Īs you can see, this is a very basic use of matplotlib's PyPlot. The following also demonstrates how transparency of the markers can be adjusted by giving alpha a value between 0 and 1. ot(total_lengths, sort_times_bubble, 'b-', To create a scatter plot with a legend one may use a loop and create one scatter plot per item to appear in the legend and set the label accordingly. Please consider the graphing script below: if _name_ = '_main_': In some cases, it is not possible to set the label of the handle, so it is possible to pass through the list of labels to legend (): lineup, plt.plot( 1,2,3, label'Line 2') linedown, plt.plot( 3,2,1, label'Line 1') plt.legend( lineup, linedown, 'Line Up', 'Line Down') Creating artists specifically for adding to the legend (aka. For example, the MATLAB audioplayer function creates a handle object that contains the audio source data to reproduce a. This reference behavior means that if h identifies a handle object, then, h2 h Creates another variable, h2, that refers to the same object as h. How can one create a legend for a line graph in Matplotlib's PyPlot without creating any extra variables? All copies of a handle object variable refer to the same underlying object. ![]()
