mmhh. seems as if the first part of the message has been eaten by the
system...
ChartDroid integrates works great when having two timeseries
(SeriesList.length = 2, Titles.length = 2) to display on a xy-chart.
For some special chart I need only one timeseries (SeriesList.length =
1, Titles.length = 1, as well xy-chart) and this makes CD always
crash. The log is in the first post.

solved by implementing achartengine
