1. Create a new CDEF - Management/Graph Management/CDEFs:
- Click ‘Add’
- Create as per the 2nd image above
2. Create a new Graph - Management/Graph Management:
- Click ‘Turn Off Graph Debug Mode’
- Click ‘Add’
- Leave ‘Selected Graph Template’ and ‘Host’ as ‘None’
- Click ‘create’
- Give your graph a destinctive title and click ‘create’
- Add the first data source by clicking ‘Add’ beside ‘Graph Items’
- select your first data source
- select your colour
- in ‘Graph Item Type’ select ‘Area’
- in ‘CDEF Function’ select ‘Bytes into bits’
- give the data source a title
- Click ‘create’
- Click ‘add’ again and create a legend (all values the same as above, except ‘Graph Item Type’ is ‘Legend’)
- Add your second data source exactly at the first except ‘Graph Item Type’ is ‘Stack’
- add legend for second data source as above
- Continue adding sources in the same fashion until you are done.
To get the total on the graph, add another Graph Item:
- use the same data source as your last data source
- select your colour
- in ‘Graph Item Type’ select ‘Line 3′ (use Line 2 or Line 1 for smaller lines)
- in ‘CDEF Function’ select ‘Total All Data Sources and Bytes into Bits’ (the one you created at the start)
- In Text Format, call it ‘Total’.
- Click ‘create’
- Click ‘add’ again and create a legend (all values the same as above, except ‘Graph Item Type’ is ‘Legend’)
Now you should have a graph with the output from different data sources, plus a total at the bottom.
