使用matplotlib绘制直方图 首先,我们需要导入matplotlib库,并创建一个list数据,用于绘制直方图。以下是一个示例代码: importmatplotlib.pyplotasplt data=[1,2,1,3,4,4,5,6,7,8,8,9,10]plt.hist(data,bins=5)plt.xlabel('Value')plt.ylabel('Frequency')plt.title('Histogram of Data')plt.show() 1. 2...
Compute and draw the histogram of x. The return value is a tuple (n, bins, patches) or ([n0, n1, …], bins, [patches0, patches1,…]) if the input contains multiple data. Multiple data can be provided via x as a list of datasets of potentially different length ([x0, x1, …]...
另外bins_array可以用来直接转换为array。这点还挺意外的。这个少了一个数的,可以参考这个回答http://stackoverflow.com/questions/15697350/binning-frequency-distribution-in-python 3.histogram,normed我这里设置的是false,因为我设置为true的时候,统计的是概率,一直不对劲,我也没搞懂他的概率是怎么算的。false的话...

使所有数值数据及其分布可视化的最快、最有效的方法之一是利用 pandas 画直方图(histogram)。 wines.hist(bins=15, color='steelblue', edgecolor='black', linewidth=1.0,xlabelsize=8, ylabelsize=8, grid=False) plt.tight_layout(rect=(0,0,1.2,1.2)) ...
