# pandas.io.formats.style.Styler.bar

`Styler.``bar`(subset=None, axis=0, color='#d65f5f', width=100, align='left', vmin=None, vmax=None)

  Draw bar chart in the cell backgrounds.

  Parameters:

  subset : IndexSlice, optional

  > A valid slice for data to limit the style application to.

  axis : {0 or ‘index’, 1 or ‘columns’, None}, default 0

  > apply to each column (`axis=0` or `'index'`), to each row (`axis=1` or `'columns'`), or to the entire DataFrame at once with `axis=None`.

  color : str or 2-tuple/list

  > If a str is passed, the color is the same for both negative and positive numbers. If 2-tuple/list is used, the first element is the color_negative and the second is the color_positive (eg: [‘#d65f5f’, ‘#5fba7d’]).

  width : float, default 100

  > A number between 0 or 100. The largest value will cover width percent of the cell’s width.

  align : {‘left’, ‘zero’,’ mid’}, default ‘left’

  > How to align the bars with the cells.

  > - ‘left’ : the min value starts at the left of the cell.

  > - ‘zero’ : a value of zero is located at the center of the cell.

  > - ‘mid’ : the center of the cell is at (max-min)/2, or if values are all negative (positive) the zero is aligned at the right (left) of the cell.

  >   New in version 0.20.0.

  vmin : float, optional

  > Minimum bar value, defining the left hand limit of the bar drawing range, lower values are clipped to vmin. When None (default): the minimum value of the data will be used.

  > New in version 0.24.0.

  vmax : float, optional

  > Maximum bar value, defining the right hand limit of the bar drawing range, higher values are clipped to vmax. When None (default): the maximum value of the data will be used.

  > New in version 0.24.0.

  Returns: | self : Styler
