Sas proportional venn diagrams. It is easy to construct examples in which the venn diagram misrepresents the quantities that are shared between sets. I would like to use a venn diagram to show how many of the loans were. The sas code presented on this page is largely inspired by rob allisons sas code for plotting a 3 way venn diagram. Give it a try.
Set image parameters. Within our sas community there has been a highly demanding for a new sas procedure that can generate proportional venn diagrams1. The attempt on the left indicates that there are elements of c that are not. My contribution was to wrap his code into the macro presented below while refreshing it to make it more flexible and robust.
In this presentation we will introduce another sas macro which utilizes proc gplot instead to generate customized proportional venn diagrams. The macro uses annotate functions to draw the venn diagrams. Two attempts are shown below. A and c n70.
A and b n74. Biovenn a web application for the comparison and visualization of biological lists using area proportional venn diagrams. Im looking to build a proportional venn diagram using sas va. The variables are suspension reasons lets call them a b c and d for simplicitys sake.
Assigned to create a proportional venn i investigated what was available and found google charts. Please use it for the creation of area proportional venn diagrams for scientific publications and presentations. Proportional venn diagrams have a wide application background. I would like to draw a venn diagram to illustrate the following situation.
How can i do it by sas with numbers in the circles and if it can be proportional d is too big. Main improvements to the existing code include more flexible data entry options. This sas macro will. I have four variables that could overlap.
They can be used to visually demonstrate the magnitudes and relationships among subgroups. And we have unique loan numbers that could have a single suspension reason or any combination of 2 3 or 4 suspension reason. In this presentation we will propose a sas macro pvenn. In sas global forum 2009 for the first time we presented an algorithm and a sas macro that can create proportional venn diagrams.
While sas offers many complex and informative graph options a proportional venn diagram is not currently available. The simplest example with three sets is a1 and b2 and c1 2. There is no way to use circles to construct a venn diagram that represents this state correctly. Kriss harris glaxosmithkline uk summary drill down drilling down graphs html plots venn venn diagram abstract when it comes to venn diagrams most people use a combination of microsoft powerpoint to generate two or three way venn diagrams and use filtering in excel to count the numbers in each.
I saw some macroscodes. I did explain a way around this and i know of some websites where one can obtain numbers for a two and three way venn. Data and expected venn diagram are attached. Also to reduce the font size if the numbers in the groups are very large.
In my opinion the most pertinent update will be to allow the macro to accept qualitative data and hence work out the exact numbers in each group from a qualitative data set.
