Re: [R] how to plot histogram plot and fitted distributions on the same graph

Here is a direct quote from the help page for hist: "if 'FALSE', probability densities, component 'density', are plotted (so that the histogram has a total area of one)." That looks like it may apply to your problem, just figure out what the above quote is referring to. The last example on that

Re: [R] how to plot histogram plot and fitted distributions on the same graph
