Donut Chart not working as expected

    Donut Chart not working as expected

    Hi all,

    i´m trying to use a donut chart with categories and since there is no documentation how to use it, i just tried it the way it is done in Excel, which doesn´t seem to work though :(

    The first level is displayed correctly but the second is screwed somehow, instead of showing the various data series it displays only a solid full circle.

    You can see the setup and the result in the attached image.

    regards
    OMartin
