A very common type of graph contains two series plot, where the user is expected to evaluate the difference visually. I saw one such plot on the web today shown on the right. This graph has two curves, one for malpractice premiums and one for claims, with a shaded band
Sankey Diagrams have found increasing favor for visualization of data. This visualization tool has been around for a long time, traditionally used to visualize the flow of energy, or materials. . Now to be sure, GTL does have a statement design for a Sankey Diagram which was implemented only in Flex for use
Significant progress in reduction of Cancer mortality is shown in a graph that I noticed recently on the Cancer Network web site. This graph showed the actual and projected cancer mortality by year for males. The graph is shown on the right. The graph plots the projected and actual numbers
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
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
Just this morning I received a request for a brief survey from Apple on my feedback about the new iPhone6+. Yes, I finally got one, dead last in the family. The survey followed the usual format, with a number of questions on what I like or dislike about it, with
A HighLow plot is very popular in the financial industry, often used to track the periodic movement of a stock or some instrument or commodity. The CandleStick Chart is one specific type of high low plot, purportedly originating in Japan for tracking of financial instruments in the rice trade. Creating a
Often we need to plot the response values for binary cases of a classifier. The graph below is created to simulate one seen at http://www.people.vcu.edu/ web site of the shock index for subjects with or without a pulmonary embolism. In this case, the data is simulated for illustration purposes only. There
A few weeks back I wrote an article on Grouped Timeline for creating a stacked timeline for onset of different virus. The idea in that article was to display a stacked needle on a time axis using a HighLow plot. Such graphs are also referred to as EPI or Epidemic Curve
