Hi Ingrid ,
Just discard my last email where i reported a bug about renaming sheets .
actually i solved the issue . I was probably doing some mistake ,but now
i
get correct behavior .
The most important thing for me now is to arrange the vertical grid
labels
Hi Ingrid,
I'm attaching below a screen shot of the x-axis grid and labels i need to
achieve.
as you can see the x-axis should display dates with one month difference and
between two successive months ,there should be two vertical grids in between
without labels.
I'm looking for a workaround
?
thanks.

Thanks much Ingrid ,i'll try using this workaround .
As you can see this discussion may be useful to discover bugs and improve
the charting component.
I think i discovered another bug related to calc sheets renaming. here is
the situation:
1-I open a calc
be removed from sheets elements array.
thanks much .

Hi,
That is a bug. You can do the following to work around:
Query the Chart document for interface XMultiServiceFactory:
http://api.openoffice.org/docs/common/ref/com/sun/star/lang/XMultiServiceFactory.html
);
xGridProp.setPropertyValue( LineWidth, new Integer( 30 ));
}

Hi Ingrid,
as we all know the candle chart has two bars (black and white)
I guess that by changing the bar width, the chart can have a larger date
range

do you have an idea how we can implement zoom in/out for a OO.o candle chart
?
thanks.

Within the standard API the different types of diagrams do support
several axis-supplier services. For example the LineDiagram
(http://api.openoffice.org/docs/common/ref/com/sun/star/chart/LineDiagram.html)
does support ChartAxisXSupplier and
entries will show . or is it same for both standard api and chart2
api ?
I would appreciate if you point me a more efficient method to show the
missing candle chart legend entries (using chart2 API).
thanks.

the chart doesn't display the other candle series with roles
values-max ,values-first , values-min ?
it seems for candle chart only the close series are displayed in the
legend. is there a way to add the other candle series to legend entries ?
thanks much.

There is no concept of date range at a category axis in neither API.
