Histogram

Usage:

histogram plotname [-title title string] list of values

This command adds the values to a histogram plot. A record of all data values so far added to the histogram is stored in the file plotname.dat. This allows automatic recalculation of the histogram's bins whenever a data value goes out of bounds. The number of bins is also dynamically controlled by the scale widget on the side. The histogram is recalculated next time histogram is called after the number of bins has been altered. This can be a time consuming business, so it is recommended that the experiment is suspended before changing the number of bins.

There is also the option of plotting the histogram with logarithmic scales.

histogram supports the following methods:

• plotname::print filename -- produce a postscript representation to a file
• plotname::clear -- clear the plot
• plotname::outputdat filename -- output histogram to a text file
• plotname::xlogscale -- toggle logarithmic x axis
• plotname::ylogscale -- toggle logarithmic y axis
• plotname::setnbins nbins -- set the number of bins
