# BarChart 指令 ##### 指令分類 （所有指令）

BarChart[Start Value, End Value, List of Heights]
Creates a bar chart over the given interval: the number of bars is determined by the length of the list, whose elements are the heights of the bars.

BarChart[Start Value a, End Value b, Expression, Variable k, From Number c, To Number d]
Creates a bar chart over the given interval [a, b], that calculates the bars’ heights using the expression whose variable k varies from number c to number d.

BarChart[Start Value a, End Value b, Expression, Variable k, From Number c, To Number d, Step Width s]
Creates a bar chart over the given interval [a, b], the bars’ heights are calculated using the given expression in which the variable k varies from number c to number d using step width s.
BarChart[List of Raw Data, Width of Bars]
Creates a bar chart using the given raw data; the bars have the given width.

BarChart[List of Data, List of Frequencies]
Creates a bar chart using the list of data with corresponding frequencies.

• `BarChart[{10,11,12,13,14}, {5,8,12,0,1}]`
• `BarChart[{5, 6, 7, 8, 9}, {1, 0, 12, 43, 3}]`
• `BarChart[{0.3, 0.4, 0.5, 0.6}, {12, 33, 13, 4}]`
BarChart[List of Data , List of Frequencies, Width of Bars w]
Creates a bar chart using the list of data and corresponding frequencies; the bars have width w.

• `BarChart[{10,11,12,13,14}, {5,8,12,0,1}, 0.5]` leaves gaps between bars.
• `BarChart[{10,11,12,13,14}, {5,8,12,0,1}, 0]` produces a line graph.
