histogram_line

sherpa.plot.utils.histogram_line(xlo, xhi, y)

Manually create x, y arrays to replicate a histogram

Draw the data as a histogram, manually creating the lines from the low to high edge of each bin. In the case on non-consequtive bins, the line will have some nan values, so that disjoint lines are drawn.

In matplotlib, an alternative would be to create RectanglePatches, one for each bin, but I don’t want each bin to go down to 0. I do not find the existing drawstyle options to be sufficient.

Parameters:

xlo, xhiarray

Lower and upper bin boundaries. Typically, xlo will contain the lower boundary and xhi the upper boundary, but this function can deal with situations where that is reversed. Both arrays have to be monotonically increasing or decreasing.

yarray

Dependent values for each histrogram bin_hi

Returns:

x, y2array

x and y arrays for plotting the histogram line.
