Axes Synchronization

Often we need to plot multiple response variables on Y axes by a common variable on X axis. When the response variables are very different in magnitudes or format, we prefer to plot the variables on separate Y (Left) and Y2 (Right) axes. Here is some sample data with three response

Should teachers get a pay raise?

Teacher pay, and the possibility of a raise, has been a hot topic in North Carolina lately. So I decided to look around and see if I could find any good data related to teacher salary, and then try to determine the best way to present that data graphically. I found that

How much snow does it take to close your school? (here's a SAS map!)

We get very little snow in Wake County, NC (SAS Headquarters) - therefore when we do have snow, it's a big deal and they close the schools. Which made me wonder ... how much snow does it take to close schools in the rest of the US? Last week we got our

Ways to include textual data columns in graphs

Most simple graphs generally include graphical representation of data using various plot type such as bar charts, scatter plots, histograms, box plots step plots and more. Both SG procedures and GTL provide many easy ways to create such graphs. However, for many real world use cases, we need to display related textual data in

Data-driven Layouts in R's ggplot2 and ODS Graphics

Following Sanjay's cue (see “R U Graphing with SAS”), I tried creating data driven multi-cell graphs using R. I played with the lattice and ggplot2 packages. I found ggplot2 simpler to understand and use than lattice, but there are probably some trades offs. Data-driven layouts are referred to as 'faceting'
