I created a 4D scatter plot graph to represent different temperatures in a specific area. When I create the legend, the legend shows the correct symbol and color but adds a line through it. The code I'm using is: colors=['b', 'c', 'y', 'm', 'r'] lo = plt.Line2D(range(10), range(10), marker='x', color=colors[0]) ll = plt.Line2D(range(10), range(10), marker='o', color=colors[0]) l = plt.Line2D(range(10), range(10), marker='o',color=colors[1]) a = plt.Line2D(range(10), range(10), marker='o',color=colors[2]) h = plt.Line2D(range(10), range(10), marker='o',color=colors[3]) hh = plt.Line2D(range(10), range(10), marker='o',color=colors[4]) ho = plt.Line2D(range(10), range(10), marker='x', color=colors[4]) plt.legend((lo,ll,l,a, h, hh, ho),('Low Outlier', 'LoLo','Lo', 'Average', 'Hi', 'HiHi', 'High Outlier'),numpoints=1, loc='lower left', ncol=3, fontsize=8) I tried changing Line2D to Scatter and scatter . Scatter returned an error and scatter changed the graph and returned an error. With scatter , I changed the range(10) to the lists containing the data points. Each list contains either the x, y, or z variable. lo = plt.scatter(xLOutlier, yLOutlier, zLOutlier, marker='x', color=colors[0]) ll = plt.scatter(xLoLo, yLoLo, zLoLo, marker='o', color=colors[0]) l = plt.scatter(xLo, yLo, zLo, marker='o',color=colors[1]) a = plt.scatter(xAverage, yAverage, zAverage, marker='o',color=colors[2]) h = plt.scatter(xHi, yHi, zHi, marker='o',color=colors[3]) hh = plt.scatter(xHiHi, yHiHi, zHiHi, marker='o',color=colors[4]) ho = plt.scatter(xHOutlier, yHOutlier, zHOutlier, marker='x', color=colors[4]) plt.legend((lo,ll,l,a, h, hh, ho),('Low Outlier', 'LoLo','Lo', 'Average', 'Hi', 'HiHi', 'High Outlier'),scatterpoints=1, loc='lower left', ncol=3, fontsize=8) When I run this, the legend no longer exists, it is a small whit
