Description quinnman 2007-09-25 20:17:07 UTC 
It was tested in Windows (currently I don't have Linux version of OO.o 2.3). I
will attach a file illustrating the issue. In this file "chart_bug.ods" in the
Sheet3 there are data in the first two columns these data are plotted in the
chart. The central part is completely missing. The same plot in OO.o 2.2 is correct.

Comment 3 frank 2007-09-25 21:54:14 UTC 
wrong component, changed to Chart and re-assigned
Comment 4 Regina Henschel 2007-09-25 22:25:50 UTC 
It happens too, if the chart is newly created in OOo2.3.
It doesn't depend on logarithmic scaling. You can notice it too, if you switch
to normal scale. You see it, when you traverse the points with <tab> and
<shift><tab>.
It is not the amount of data points, I'll attach a smaller example.

Comment 6 bjoern.milcke 2007-09-26 08:29:09 UTC 
Too avoid the creation of too many data point symbols for large charts, some
data points may be removed (if they lie on the same point in the drawing layer
coordinate system). That's why the number of data points is less than expected
in the non-logarithmic case. There, I would see the behavior as correct.

For the logarithmic case it looks very much like this algorithm would not take
the scaling into account, i.e. the points have the same pixel position in the
untransformed system, are then removed and then the scaling transformation is
applied. This is a bug.

->iha: Please have a look.

changed component to Chart as it is clearly a Chart and not a Spreadsheet issue.
