# pandas.io.formats.style.Styler.bar¶

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

Draw bar chart in the cell backgrounds.

Parameters
subsetIndexSlice, 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.

colorstr 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’]).

widthfloat, 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.

vminfloat, 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.

vmaxfloat, 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.
