pgfhist2d

Creates a 2D histogram from data for use with PGFPLOTS

PGFHIST2D(X, Y, W) will save a PNG file representing the 2D histogram created from data points specified by X and Y with weights specified by W. The vectors X, Y, and W must have the same number of elements. The text to include in a Latex file to produce the histogram is displayed.

Valid options include:
'minX' - the minimum value for X in the histogram (default: min(X))
'minY' - the minimum value for Y in the histogram (default: min(Y))
'maxX' - the maximum value for X in the histogram (default: max(X))
'maxY' - the maximum value for Y in the histogram (default: max(Y))
'binsX' - the number of equally spaced bins for X in the histogram
(default: 100)
'binsY' - the number of equally spaced bins for Y in the histogram
(default: 100)
'filename' - the name of the file for the PNG image
(default: 'test.png')
'logarithmic' - use a logarithmic scale (default: false)
