LinePointSeries.
13) [No bugfix log]
Exporting a large number of times the Chart to
PDF (i.e. 5000) in a loop "out of resources"
error appears. We've been investigating the
cause of the problem and trying to find a good
solution, however, we'ven't found a fix for it.
The problem is that when the Chart is exported
to PDF for a this large number of times, if
smooth shadows are used into the Chart, the
resources wasted are growing and growing until
the error appears. We've tried to control this
consumption with no luck.
So, at the end a workaround for these case when
the number of exportations are really big would
be to hide the shadows or just set the shadow
smooth to false.
14) [TF02012544]
Zooming or scrolling on a IBubbleSeries
caused bubbles at the edges of the
chart to "disappear". Fixed.
15) [TF02013413]

incorrect FirstDisplayedIndex and
LastDisplayedIndex values to be returned.

ITagCloudSeries threw an exception when
