This is the same as Example 5.14, “Stacked Bars, Shaded” except we have turned off shading and now get flat stacked bars with borders. Also in this example we changed the legend using SetLegendReverse so the lines of text and color boxes are in the same order as the stacked bar segments, bottom-to-top.
