Hello Guys,
In my WAD analysis item, it will dispaly some courses. when you click each course, I would like to draw a pie chart for this course.
For each course, it may have different number of groups, and each group has different number of people attending this course.
The I would like the pie chart to display the group distribution for each course.
For example,
Course 1
Group Name People attend from this group
Group 1 5
Group 2 3
Course 2
Group Name People attend from this group
Group 1 4
Group 2 3
Group 3 5
I define the groupname as charactoristic Group, the people attend is the key figure numberAttend.
So the number of group for each course is dynamic, and I'd like to display it.
I got two questions,
1) Should I use command to dynamicly refresh the dataset for the pie chart when I click different rows of course?
2) As there are little document on how to design a pie chart, I could not get the correct pie chart.
For example, for course 1.
I can configure the dataprovider for the pie chart,
But I don't where to configure my charactoristic group and key figure numberAttend.
And need I configure it only has one data series? how about the category count ? (group number is dynamical)
Could somebody give me a detail how to configure such parameters, or give me some document links on how to configure the pie chart, I looked some document but they are not detail and not fix my issue
Thanks a lot..
