# pandas.DataFrame.plot.barh

DataFrame.plot.barh(x=None, y=None, **kwargs)

  Make a horizontal bar plot.

  A horizontal bar plot is a plot that presents quantitative data with rectangular bars with lengths proportional to the values that they represent. A bar plot shows comparisons among discrete categories. One axis of the plot shows the specific categories being compared, and the other axis represents a measured value.

  Parameters:
    x label or position, optional

      Allows plotting of one column versus another. If not specified, the index of the DataFrame is used.

    y label or position, optional

      Allows plotting of one column versus another. If not specified, all numerical columns are used.

    color str, array-like, or dict, optional

      The color for each of the DataFrame’s columns. Possible values are:

      - A single color string referred to by name, RGB or RGBA code,

          for instance ‘red’ or ‘#a98d19’.

      - A sequence of color strings referred to by name, RGB or RGBA

          code, which will be used for each column recursively. For instance [‘green’,’yellow’] each column’s bar will be filled in green or yellow, alternatively. If there is only a single column to be plotted, then only the first color from the color list will be used.

      - A dict of the form {column namecolor}, so that each column will be

          colored accordingly. For example, if your columns are called a and b, then passing {‘a’: ‘green’, ‘b’: ‘red’} will color bars for column a in green and bars for column b in red.

    **kwargs

      Additional keyword arguments are documented in `DataFrame.plot()`.

  Returns:
    matplotlib.axes.Axes or np.ndarray of them

      An ndarray is returned with one `matplotlib.axes.Axes` per column when `subplots=True`.

  Examples

  Basic example

      >>> df = pd.DataFrame({'lab': ['A', 'B', 'C'], 'val': [10, 30, 20]})
      >>> ax = df.plot.barh(x='lab', y='val')

  Plot a whole DataFrame to a horizontal bar plot

      >>> speed = [0.1, 17.5, 40, 48, 52, 69, 88]
      >>> lifespan = [2, 8, 70, 1.5, 25, 12, 28]
      >>> index = ['snail', 'pig', 'elephant',
      ...          'rabbit', 'giraffe', 'coyote', 'horse']
      >>> df = pd.DataFrame({'speed': speed,
      ...                    'lifespan': lifespan}, index=index)
      >>> ax = df.plot.barh()

  Plot stacked barh charts for the DataFrame

      >>> ax = df.plot.barh(stacked=True)

  We can specify colors for each column

      >>> ax = df.plot.barh(color={"speed": "red", "lifespan": "green"})

  Plot a column of the DataFrame to a horizontal bar plot

      >>> speed = [0.1, 17.5, 40, 48, 52, 69, 88]
      >>> lifespan = [2, 8, 70, 1.5, 25, 12, 28]
      >>> index = ['snail', 'pig', 'elephant',
      ...          'rabbit', 'giraffe', 'coyote', 'horse']
      >>> df = pd.DataFrame({'speed': speed,
      ...                    'lifespan': lifespan}, index=index)
      >>> ax = df.plot.barh(y='speed')

  Plot DataFrame versus the desired column

      >>> speed = [0.1, 17.5, 40, 48, 52, 69, 88]
      >>> lifespan = [2, 8, 70, 1.5, 25, 12, 28]
      >>> index = ['snail', 'pig', 'elephant',
      ...          'rabbit', 'giraffe', 'coyote', 'horse']
      >>> df = pd.DataFrame({'speed': speed,
      ...                    'lifespan': lifespan}, index=index)
      >>> ax = df.plot.barh(x='lifespan')
