histogram
Creates a simplified histogram representation of selected data.
Syntax
histogram(vector, scalar1, 1|2|3, [on|off])
Arguments
- vector
- The vector of data to analyze.
- scalar1
- The number of cells in the histogram or the vector of user-defined cells.
- 1|2|3|4|5
- Return mode.
- 1 = interval data (usually used as the X vector)
- 2 = frequency data (usually used as the Y vector)
- 3 = relative frequency data (usually used as the Y vector)
- 4 = cumulative frequency
- 5 = cumulative relative frequency
- 1|2
- Interval calculation (optional).
- 1 = inclusive (default)
- 2 = exact
- 0|1
- Flag to turn on debug mode and print to the message log (optional).
- 0 = off (default)
- 1 = on
Example
{histogram({50,66,70,60,90,90,81,30,99},4,1,2,1)}
Comments
Given a vector of data, a histogram is a plot showing the frequency (or relative frequency) that a given value appears in the vector.
For example: V1 = {1,2,2,3,4,4,4}
The frequency of 1 is 1 (rel. freq. = 1/7 = 14.3%).
The frequency of 2 is 2 (rel. freq. = 2/7 = 28.6%).
The frequency of 3 is 1 (rel. freq. = 1/7 = 14.3%).
The frequency of 4 is 3 (rel. freq. = 3/7 = 42.9%).
