第6章 数据可视化工具——Matplotlib Python数据分析基础教程(第2版) 分析变量数据分布和分散状况 Matplotlib 概述 使用 pyplot 创建图表 Matplotlib 参数配置 分析变量间关系 项目实践 本章小结 绘制直方图 直方图(histogram)也称为频数分布直方图,它与柱形图的形状类似,却有着与柱形图完全不同的含义。直方图涉及统计学...
看到这里,对柱状图的堆积应该有了一个较好的理解了吧 ?...回到我们虚构的数据,使用默认的matplotlib参数,代码如下: fig,ax = plt.subplots(figsize=(8,5),dpi=200) label = [i for i in bar_data.columns...总结 堆积柱状图算是柱状图中较多出现的图表,本期推文也算是对其进行简单的讲解了,加上此类图表,...
One straightforward way to plot a two-dimensional histogram is to use Matplotlib’s plt.hist2d function (Figure 4-38): In[12]: plt.hist2d(x, y, bins=30, cmap='Blues') cb = plt.colorbar() cb.set_label('counts in bin') Figure 4-38. A two-dimensional histogram with plt.hist2d ...
multi-column, and expand mode. - JJL2008-12-01 Fixed histogram autoscaling bug when bins or range are given explicitly (fixes Debian bug 503148) - MM2008-11-25 Added rcParam axes.unicode_minus which allows plain hypen for minus when False - JDH2008-11-25 Added scatterpoints support in ...
