BarChart Command

BarChart[ <List of Data>, <List of Frequencies> ]

Creates a bar chart using the list of data with corresponding frequencies.

Note: The numbers in the list of raw data need to be arranged in increasing order.

Example:

• 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 Raw Data>, <Width of Bars>]

Creates a bar chart using the given raw data; the bars have the given width.

Example: BarChart[ {1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 5, 5, 5, 5}, 1]

BarChart[ <List of Data> , <List of Frequencies>, <Width of Bars> ]

Creates a bar chart using the list of data and corresponding frequencies; the bars have width w.

Example:

• 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.

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.

Example: BarChart[10, 20, {1, 2, 3, 4, 5} ] gives you a bar chart with five bars of specified height in the interval [10, 20].

BarChart[ <Start Value>, <End Value> , <Expression>, <Variable>, <From Number>, <To Number> ]

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

Example: If p = 0.1, q = 0.9, and n = 10 are numbers, then BarChart[ -0.5, n + 0.5, BinomialCoefficient[n,k] * p^k * q^(n-k), k, 0, n ] gives you a bar chart in the interval [-0.5, n+0.5]. The heights of the bars depend on the probabilities calculated using the given expression.

BarChart[ <Start Value>, <End Value>, <Expression>, <Variable>, <From Number>, <To Number>, <Step Width> ]

Creates a bar chart over the given interval [Start Value, End Value], 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.
