Can someone please help me put together a dual pie chart, or suggest a way of visualising the following information.
The data I am using is to analysis employees time sheets. I am looking at the number of hours spent on each job type, I show this as pie chart by %. I use this to check employees utilisation based on the type of job type they are working on. I have another dimension which then tells me if the time has been charged to the client of written off.
So basically I want to should the overall time spent on a job type, then the split between written off and charged for each job type.
