Graphically Speaking
Data Visualization with a focus on SAS ODS Graphics
Last week I posted an article on displaying polar graph using SAS. When the measured data (R, Theta) are in the polar coordinates as radius and angle, then this data can be easily transformed into the XY space using the simple transform shown below. x=r*cos(theta * PI / 180); y=r*sin(theta * PI
There are many situations where it is beneficial to display the data using a polar graph. Often your data may contain directional information. Or, the data may be cyclic in nature, with information over time by weeks, or years. The simple solution is to display the directional or time data
Recently, I needed to view the list of products with the highest number of defects. I have a data set of defects reported against various products. The data set has over 30 products, and each observation contains the product name, name of the primary support person, and other relevant details of
