barWidth

[Optional] Bar width, in pixels. Enter 'spaceBetweenBars' and 'spaceBetweenGroups' also in absolute values, in pixels. Bars can be clipped if the chart isn't wide enough. Use 'auto-absolute' or 'auto-relative' to have bars resized so that all bars will fit in the chart.

Absolute values: Values are given in absolute units (or default absolute values, if not specified). Bars will be resized so that all bars will fit in the chart

Relative values:  Values are given in relative units (or default relative values, if not specified) Relative units are floating point values compared to the bar width, where the bar width is 1.0: for example, 0.5 is half the bar width, 2.0 is twice the bar width. Bars can be clipped if the chart isn't wide enough.
