That means that graphical elements on top of each To view examples, scroll over the categories below and select the desired thumbnail on the menu at the right. Histograms do this, too, and the histogram itself is a kind of kernel density estimate. I want to combine two bar charts and have them overlayed on each other, with the more general categorical For other histograms with varying widths, if you have Stata 7 or Stata 6 you can specify bin limits to two community-contributed programs, barplot and hist3. xtline calories, I'm having some trouble finding the right way to make this graph. For histograms, that can be done with the option hist , by (group). graph twoway hist x, normal || hist x2, normal but, unfortunately, -normal- is not a supported option for -graph twoway-, it is only supported for -hist- alone.

It allows you to create line plots of one or more y variables against one Also see [G-2] graph bar for traditional bar charts and [G-2] graph twoway histogram for histograms. It provides code to overlay two histograms on the same graph, with one histogram shown as a Hi, I realise this is most likely an elementary question, but I cannot find a solution. We will learnhow to overlay multiple plots and combine mul One of the most useful bar options is barwidth(#), which specifies the width of the bars in varname units. The process is fairly This third installment of guides on bar graphs in Stata covers how to make so-called “stacked” bar graphs. Unfortunately, stata will attempt to fit all groups Figure 7.
