python作图（Matplotlib: Visualization with Python）

直方图

axs.hist(x, bins=n_bins)
# bins：间隔数量

组合图表显示

axs = plt.figure(figsize=figsize, constrained_layout=True).subplots(rows, cols)

中文显示错误

 plt.rcParams['font.sans-serif'] = ['SimHei']
 plt.rcParams['axes.unicode_minus'] = False

保留指定位数的小数

format(number, '.3f')

常用字体及相关参数

families = ['serif', 'sans-serif', 'cursive', 'fantasy', 'monospace']
alignment = {'horizontalalignment': 'center', 'verticalalignment': 'baseline'}
t = plt.figtext(0.1, 0.9, 'family', size='large', **alignment)

styles = ['normal', 'italic', 'oblique']

weights = ['light', 'normal', 'medium', 'semibold', 'bold', 'heavy', 'black']
