-        Histogram
+        Draw one histogram of the DataFrame's columns.
+
+        A histogram is a representation of the distribution of data.
+        This function groups the values of all given Series in the DataFrame
+        into bins, and draws all bins in only one :ref:`matplotlib.axes.Axes`.
+        This is useful when the DataFrame's Series are in a similar scale.
 
         Parameters
         ----------
-        by : string or sequence
+        by : str or sequence, optional
             Column in the DataFrame to group by.
-        bins: integer, default 10
-            Number of histogram bins to be used
-        `**kwds` : optional
+        bins : int, default 10
+            Number of histogram bins to be used.
+        **kwds
             Additional keyword arguments are documented in
             :meth:`pandas.DataFrame.plot`.
 
         Returns
         -------
-        axes : :class:`matplotlib.axes.Axes` or numpy.ndarray of them
+        axes : matplotlib.AxesSubplot histogram.
+
+        See Also
+        --------
+        DataFrame.hist : Draw histograms per DataFrame's Series.
+        Series.hist : Draw a histogram with Series' data.
+
+        Examples
+        --------
+        When we draw a dice 6000 times, we expect to get each value around 1000
+        times. But when we draw two dices and sum the result, the distribution
+        is going to be quite different. A histogram illustrates those
+        distributions.
