Graphically Speaking
Data Visualization with a focus on SAS ODS Graphics
Over the Christmas Holidays I saw an graph of agricultural exports to Russia in 2013. The part that caught my eye was the upper part of the graph, showing the breakdown of the trade with Russia as a horizontal stacked bar with custom labels. The value for each region / country
Last week a user expressed the need to create a graph like the one shown on the right using SAS. This seems eminently doable using GTL and I thought I would undertake making this graph using SAS 9.3. The source data required to create this graph is only the
Often we need graphs that display two or more responses by the same category values. In many cases it is useful to plot both responses on the same response (Y) axis. This can be helpful to understand the data and compare the magnitudes side by side. This works when the scales
A common scenario is where we have a table of multiple measures over time. Here we have a simple example of Frequency and Response by Day. The Response is a linear function of the Frequency, as shown in the table on the left below. The shape of the data is
As Sheldon Cooper would say, this is the first episode of "Fun with Charts". I did not find a cool term like "Vexillology" and "Cartography" is taken by map making, so let us go with "Chartology". Yesterday, I saw a couple of interesting bar charts as shown on the right. I thought
Often, we have data where most of the observations are clustered within a narrow range, with a few outliers positioned far away. When all the data is plotted, the axis is scaled to accommodate all the data, thus skewing the scale. Techniques to handle such data have been addressed earlier
