This is pretty straightforward. There's a little bit of calculation involved in getting the heights of the curves to line up reasonably, but otherwise it's pretty basic. First plot a histogram. If you want a box around it, like your example, do that. Then you'll need to call lines() 6 times to plot the 6 normals. In R, lines are just a sequence of interpolated points—(x,y) coordinates—so make a sufficiently fine-grained set of x coordinates, then compute the normal density for each component using dnorm() and the fitted parameters. You'll need to multiply those y-values by the appropriate proportion and a height adjustment factor to get the heights of the curves right. It turns out that the highest bin in your histogram is 82, which is approximately the peak of your third component, but since that represents only 30%, you need to rescale the adjustment factor by that. You may want to choose your own colors. Consider:
