*** this is an enhancement request, not a bug ***
Tha graph shown on first page of tutorial at
http://cewolf.sourceforge.net/tutorial.html shows the
data plotted such that both lines and points are seen.
However the taglib has only "line" option for the
cewolf:chart tag's type attribute which does not
display the graph as shown in the tutorial.
There should be a way to specify something like
"linespoints" type which will display both: points for
the data values and lines connecting the points.
