The query that generates this graph is of the form: plugin:disk AND type:disk_octets AND (host:machine10* OR host:machine20* ...)
Is there a way to convert this line chart into a cumulative sum, i.e., showing 1 line that is the sum of all the 25 values in each bin. Something that would show "total Disk I/O for the system" rather than on a per machine basis.
Sure! The original query and formatting of the plot had the split-line aggregation, which once I removed resulted in plotting the cumulative sum of values in each bucket.
