Sample 48333: Create a broken axis panel graph using the GCHART and GREPLAY procedures
 |  |  |  |  |  |
This sample uses the GCHART procedure together with the GREPLAY procedure to create a broken axis panel graph. The data for the vertical axis variable used in this sample ranges from 0 to 220. However, the graph that this sample code creates is a two-panel graph, where the vertical axis range for the lower graph ranges from 0 to 25 and the vertical axis range for the upper graph ranges from 205 to 220.
The sample code on the Full Code tab first uses DATA step code to separate the original data set into two unique data sets. Two GCHART procedure steps are then used to create the two individual graphs. In a final step, the GREPLAY procedure is used to stack the two graphs on top of each other.

Note that this sample code is very data dependent. You will have to make significant changes to the sample code to get it to work with your data. Also, a certain amount of trial and error will be necessary in order for the final GREPLAY graph to line up properly.
