First you have to build the pie chart using :
- the usual Excel charting engine (note: take out all details such as caption)
- or the micro-charts library included inside BeGraphic ("SFE" menu)
Then you have to put this pie chart on the maps. There are two possibilities :
- directly put the usual pie chart on the map (put an invisible background : format chart area / fill / no fill)
- or use the "sub-dashboard" function to copy a range of cell (showing a pie chart) on the map
Note : the "sub-dashboard" function is the one that allows you to dynamically change the total size of the pie chart (not only its slices).
