如何使用 Python 一次绘制数据帧中的所有单个直方图？

Question

我有一个包含多列的数据框，我想一次绘制它们，我尝试使用 for 循环我不断收到错误

Try something like this :

    for i in range(n_samples):
    pyplot.subplot(n_rows, n_columns, 1 + i)
    pyplot.axis('off')
    pyplot.imshow(Dataframe[i,:,:,:])

n_samples = Number of your samples you want to plot (number of histograms)

Dataframe = for example a numpy array which you can call with [i,:,..,:]

n_rows = Number of rows you want, but n_rows*n_colums=n_samples

n_columns = Number of rows you want, but n_rows*n_colums=n_samples

For example wrap it to:

    for i in range(n_samples):
    pyplot.subplot(n_rows, n_samples, 1 + i)
    pyplot.axis('off')
    pyplot.imshow(Dataframe[i,:,:,:])

For example:

n_colums=3, n_rows=2, n_samples=6
