Synopsis
Create a 1D histogram from a binned grid and array of samples
Syntax
histogram1d( x, xlo, xhi )
Description
The histogram1d command returns a histogram array from an array of samples and a binned grid.
- x - array of x values
- xlo - array of lower bin edges
- xhi - array of upper bin edges
Example
sherpa> dataspace1d( 0.1, 10, 0.1 ) sherpa> lo, hi = get_indep() sherpa> n = histogram1d( vals, lo, hi ) sherpa> set_dep( n )
A 1d histogram is stored in the blank data set created by the dataspace1d and set_dep commands.
