Stacked horizontal bar charts possible in SAS with 300 bars?

RandoDando — Thu, 16 Nov 2023 19:30:10 GMT

I am working on an analysis by city, where I have percents/proportion of totals spent in 6 different categories at each city. I would like to present this in a way which makes these proportions stand out while also being able to compare all cities. I am picturing a stacked horizontal bar chart, with each city having a bar, but I'm afraid that would be too many bars for SAS graph. I haven't tried it yet, I'm afraid it may crash my session. So, before I do I want to know whether it's possible OR if there's another more efficient "visual" solution apart from just showing numbers.

I don't know if the software can handle this without crashing, but I am certain your audience will not be able to visually distinguish which bar represents which city.

Better, you should do some geographic plotting of your data like this PROC SGMAP example.

This was my other solution, maybe having separate maps for each category, then putting them together in a template. However, I was hoping there would at least be some visual feature in Proc Report that would do this.

By SAS Graph do you mean the old device based procedures like Gchart? The newer SGPLOT/SGPANEL have more options.

The following apply to Sgplot (or Sgpanel):

You might consider using a VECTOR plot. That would require a bit more work on your part as you would need to calculate the start/end value for each segment but I think it is less likely to have issue with the number of plot items. The real question may be how indicate the city as text has to be readable.

Or maybe a Heatmap. On dimension as the city (I think you need to have the variable as numeric and use the Bin options to make each city one bin) then have the 6 categories as the other and use a calculated value (percent? rate?) as a response to show "low" to "high" values.

Maybe you could try HEATMAP .
