Usage: ax.getlegend ().remove () or legend ax.legend (.). There exists 3 quiz/question(s) for this tutorial. 11 Answers Sorted by: 418 As of matplotlib v1.4.0rc4, a remove method has been added to the legend object. ![]() Next, we can assign the plot's title with plt.title, and then we can invoke the default legend with plt.legend(). With plt.xlabel and plt.ylabel, we can assign labels to those respective axis. Plt.title('Interesting Graph\nCheck it out') The rest of our code: plt.xlabel('Plot Number') 5 Answers Sorted by: 157 2D scatter plot Using the scatter method of the matplotlib.pyplot module should work (at least with matplotlib 1.2.1 with Python 2.7.5), as in the example code below. Here, we plot as we've seen already, only this time we add another parameter "label." This allows us to assign a name to the line, which we can later show in the legend. You can also add custom labels to each element legend (if you want abcde instead of 12345). Lastly, add a label name to your second scatter plot and call plt.legend () to show both. Then, add that legend to the ax with addartist. To create a scatter plot with a legend one may use a loop and create onescatterplot per item to appear in the legend and set the labelaccordingly. We have the penguins data on ’s github page. import pandas as pd import matplotlib.pyplot as plt We will use Palmer penguins data for making the scatter plot. Let us load Pandas and Matplotlib’s pyplot. This way, we have two lines that we can plot. 1 Answer Sorted by: 1 First, change your legend declaration to the following legend1. In this tutorial, we will learn how to add right legend to a scatter plot colored by a variable that is part of the data. Then, add that legend to the ax with addartist. You can pass the unique IDs you want a label to be created for into the num argument of. To start: import matplotlib.pyplot as plt First, change your legend declaration to the following legend1. Custom legends in Matplotlib This post explains how to customize the legend on a chart with matplotlib. 1 Answer Sorted by: 2 matpotlib is currently inferring you colors to be on a continuous scale instead of a categorical one. 0.0 is at the base the legend text, and 1.0 is at the top. A lot of times, graphs can be self-explanatory, but having a title to the graph, labels on the axis, and a legend that explains what each line is can be necessary. The vertical offset (relative to the font size) for the markers created for a scatter plot legend entry. I can't figure out what I am doing wrong, I've tried several things hat I have found online but nothing seems to work.In this tutorial, we're going to cover legends, titles, and labels within Matplotlib. ![]() Then use ax.legend () which will recognize the label and add legends. ![]() Plot your cluster one by one with kwarg label. Note that artists whose label start with an underscore are ignored when legend() is called with no argument. scatter-plot Share Improve this question Follow edited May 11 at 17:31 Trenton McKinney 55.6k 33 138 151 asked at 17:54 Vince 195 1 2 7 1 Maybe try check the example. No artists with labels found to put in legend. Whenever I run this, I get a series of warnings like this: So far here's the code I have tried (avg_height and avg_weight are pretty self-explanatory and classification is the classification attributed base on the inteligence level): fig, ax = plt.subplots()įor classif in whole_info_obey.unique():įilt_data = whole_info_obey=classif]Īx.scatter(x=filt_data, y=filt_data, c=filt_data.map(color_dict)) I'm trying to scatter them by height and weight and color them by classification but I'm failing to create a legend for this graph. I'm currently exploring a dataset from kaggle with information of dog breeds, their inteligence and their size. ![]()
