Do any of you know how I could force the histogram output for two different lists to appear starting and ending at the same x-local. For example, I have a list of observed data points and a list of a theoretically produced distribution. Histogram[observed]; Histogram[theoretical]; Produces very nice plots, but one has the y-axis starting at x=-1 while the other has its at the origin. One also displays different number of x-ticks (but this is a smaller inconvenience). I tried passing GraphicsOptions to the Show command, but some of these are not recognized. For example h1 = Histogram[observed]; h2 = Histogram[theoretical]; Show[h1,PlotRegion->{{xmin,xmax},{ymin,ymax}}]; Show[h2,PlotRegion->{{xmin,xmax},{ymin,ymax}}]; doesn't work? Isn't Histogram a Graphics Object? Doug
