# BarChart Command

From GeoGebra Manual

- BarChart[Start Value, End Value, List of Heights]
- Creates a bar chart over the given interval where 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 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*runs 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 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*], that calculates the bars’ heights using the expression whose variable*k*runs 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 whose 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]
- Creates a bar chart using the list of data with corresponding frequencies.
- Note: The List of data must be a list where the numbers go up by a constant amount.
- Examples:
`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 whose bars are of width
*w*. - Note: The List of data must be a list where the numbers go up by a constant amount
- Examples:
`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.
