odds ratios, graphing positive and negative associations together

How do you graph, on one chart, the results of discrete choice logistic regression in which there are positive and negative associations (odds ratios above and below one) for different categories of different variables? Excel, SAS, SPSS and SUDAAN don’t seem to offer anything.

I have been doing it by creating a bar chart, with the origin at 1, that shows the magnitude correctly i.e. 0.2, 0.33, 1.0, 3.0, 5.0 as symmetrical, by transforming the odds ratios, and relabeling the grid.

Any suggestions?
