Roses are red, violets are blue...

This classic start to a romantic poem assumes that the correct colors are always assigned to the correct flowers; but, for those who create graphs for reports, consistent color assignment can be more of a challenge than an assumption. This challenge is particularly true for the display of group values.

Celebrate your own free copy of my book "Building Business Intelligence Using SAS"

Well, we can't really afford to give everyone a free copy of the Building Business Intelligence Using SAS: Content Development Examples. But copies will be presented to two randomly selected participants of today's AllAnalytics.com eChat! Then you can be a part of the celebrations! Yes, that's right! People have been

Dashboard graphs revisited

Here is the promised follow up on the Dashboard graph.  In the previous article, I posted the code to create a panel of bullet KPIs displaying three different metrics.  For each KPI, I used 5 columns of data which resulted in a wide and inconvenient structure. A more convenient data structure is

Dashboard graphs

In this blog we have been discussing graphs useful for analysis of data for many domains such as clinical research, forecasting and more.  SG Procedures and GTL are particularly suited for these use cases.  So, when I came upon a dashboard image from Steven Few's Visual Business Intelligence blog, showing the

Beer, diapers and heat map

The parable of beer and diapers is often related when teaching data mining techniques.  Whether fact or fiction, a Heat Map is useful to view the claimed associations.  A co-worker recently enquired about possible ways to display associations or dependency between variables.  One option is to show the dependency as a node

Comparative density plots

Recently a user posted a question on the SAS/GRAPH and ODS Graphics Communities page on how to plot the normal density curves for two classification levels in the same graph. We have often seen examples of a  distribution plot of one variable using a histogram with normal and kernel density curves.  Here is a simple example: Code Snippet:

A (tool)tip for band plots

Recently, I had a discussion with a user concerning the volume of imagemap data generated for an interactive,  web-based visual contain a large number of graphs. The large amount of imagemap data was causing problems with the current version of their web browser. The graphs consisted of either bar charts

Here are a couple of bar charts showing the city mileage of cars by Type and Origin using the SGPLOT procedure from the sashelp.cars dataset. title 'Vehicle Mileage by Type'; proc sgplot data=cars; format mpg_city 4.1; vbar type / response=mpg_city stat=mean datalabel; xaxis display=(nolabel); run; title 'Counts by Country'; proc sgplot

Timeseries plots with regimes

Recently we discussed the features of the Shiller Graph, showing long term housing values in the USA.  To understand the features necesary in the SGPLOT procedure to create such graph easily, it was useful to see how far we can go using GTL as released with SAS 9.2(M3). I got the data Shiller Housing index data

They go where you put them

An issue that SAS/GRAPH users have wrestled with in the past has been how to put tick marks at irregular intervals on their axes. In PROC GPLOT, if you specify irregular intervals using the ORDER option on the AXIS statement, the procedure’s axis kicks into a “discrete” mode, where the

The more the merrier

Often it is useful to view multiple responses by a common independent variable all in the same plot.  SGPLOT procedure and GTL support the ability to view two responses, one each on the Y and Y2 axes by one independent variable (X) in one graph.  Yes, you can also have X

Custom confidence intervals

Recently a user posted a question on the SAS/GRAPH and ODS Graphics Forum about drawing a plot with custom confidence intervals .  The user has a simple data set with category, response (mean) and custom lower and upper confidence intervals.  The data looks like this: Robert Allison provided the code (proc gplot +

In good company

A recent post on the SAS website shows the SAS Annual Revenue History.  It would be interesting to see how we could create such a graph using SG procedures, and how we could add more information and interest in the presentation.  So, I started with the basic informaiton on the annual revenues provided,

Simply useful

Let us ring in the new year with something simple and useful. A recent question by a user over the holidays motivated this article on what is likely a commonly used graph.  We want to compare the preformance of two categories along with a third measure.  This could be something like "How

Map overlays

In Simple maps can go a long way, we discussed some techniques to create simple outline maps from map datasets in the MAPS library using GTL.  Now, let us take this a step further to do something more useful with this feature. For some graphs, the map information is an essential part of the
