Plot rainfall totals and rainfall tendencies.
Rainfall tendencies are calculated based on how the data is read. If every time period is read, then the rainfall tendencies will be between every available time period. If every second time period is read (as in this example), the rainfall tendencies will be calculated between every second time period.
This script has been designed to plot rainfall and rainfall tendencies when all input data is available in one input file. Do not use this script "as is" for data in multiple input files.
