Hi,
After thinking more about it, integrating jfreechart with UNO might not be a
good idea : it will make things more complex rather than help simplifying my
task.
Now I'm in a quit uncomfortable situation :
1)the standard chart API doesn't provide feature to superimpose two

Hi,
I figured out the error i was making :
i had to replace service name com.sun.star.chart2.LabeledDataSequence with
com.sun.star.chart2.data.LabeledDataSequence
Now i can get some interesting results: i got the stock chart drawn; however
it seems that the x-axis values are not set properly

You didn't add any data series to the chart type so far, so there is
nothing to display. For the roles of the different data sequences for
the stock chart have a look here:

further. When the API evolves your code will not work with future

risk
