NettetPlotting multiple sets of data. There are various ways to plot multiple sets of data. The most straight forward way is just to call plot multiple times. Example: >>> plot(x1, y1, 'bo') >>> plot(x2, y2, 'go') Copy to clipboard. If x and/or y are 2D arrays a separate data set will be drawn for every column. NettetLines have many attributes that you can set: linewidth, dash style, antialiased, etc; see matplotlib.lines.Line2D. There are several ways to set line properties Use keyword arguments: plt.plot(x, y, linewidth=2.0) Use the setter methods of a Line2D instance. plot returns a list of Line2D objects; e.g., line1, line2 = plot (x1, y1, x2, y2).

Nettet13. mai 2009 · Hi, I’m trying to plot two thick lines that are separated only by a constant. import matplotlib.pyplot as plt import numpy as np shift = .1 x = np.linspace(0,10,100) y1 = np.sin(x) y2 = y1 + shift lw = 10 alpha = .8 plt.plot(x, y1, linewidth=lw, alpha=alpha) plt.plot(x, y2, linewidth=lw, alpha=alpha) Visually, the result is not desirable. The … NettetAfter that, use the probabilities and ground true labels to generate two data array pairs necessary to plot ROC curve: fpr: False positive rate s for each possible threshold. tpr: True positive rate s for each possible threshold. We can call sklearn's roc_curve () function to generate the two. Here is the code to make them happen. Nettet17. jul. 2024 · Matplotlib defines linewidths in points and its default is to have 72ppi. It also uses a default of 100dpi. So this means each point of linewidth takes up .72 dots or pixels. Thus I would expect to see linewidths less than 0.72 to be one pixel wide, those from 0.72 - 1.44 to be two pixels wide, and so on. But this is not what was observed. grand coton tige
