Demo of the histogram (hist) function with a few features.In addition to the basic histogram, this demo shows a few optional features:* Setting the number of data bins * The ``normed`` flag, which normalizes bin heights so that the integral of the histogram is 1. The resulting histogram...
数据的分布是由直方图来表示的。当使用FunctionPandasDataFrame.hist()时,它会自动对DataFrame中的每个系列调用函数matplotlib.pyplot.hist()。结果,我们得到了每一列的柱状图。 语法:DataFrame.hist(data, column=None, by=None, grid=True, xlabelsize=None, xrot=None, ylabelsize=None, yrot=None, ax=None, ...
DataFrame.hist() function The hist() function is used to make a histogram of the DataFrame’s A histogram is a representation of the distribution of data. This function calls matplotlib.pyplot.hist(), on each series in the DataFrame, resulting in one histogram per column. Syntax: DataFrame.h...
