parameter definition

The bar chart function takes a single configuration parameter.

data	Array of Numbers, or 2 Dimensional Array of Numbers	required	An array of values to chart.

The values may themselves be arrays, but must all have the same length.
labels	Array of Strings	required	An array of string labels corresponding by index to the associated data element.
legendLabels	string labels	optional	An array of labels for the bar colors. For example, you could chart visits per day, with each browser in a different color.
stacked	boolean	optional, default is false	If true, the bars will be stacked instead of side-by-side.
colors	Array of Strings	optional	Supply custom colors for the bars.
showValues	boolean	optional, default is false	If true, the value will be shown near the top of each bar.
