To sort the elements on your chart, go to the Format Chart menu tab. Click on Labels and Sorting to open that section. Chart elements can be sorted along the x-axis in descending or ascending order according to the element totals or in alphabetical order according to the x-axis text.
For three variable charts, the segments of the element can be sorted in descending or ascending order according to the value for that segment or by the text in the legend.
