Hi Ingrid,
I wrote the below java code to insert a new chart from which i'll later
extract the XChartDocument instance.
the below java code works ok . however i noticed a couple of things :
1) i need to specify a XCellRange and get the CellRangeAddress . for this i
used :
XCellRange myRange = oRange.getCellRangeByName("A1:E1740");
XCellRangeAddressable oRangeAddr = (XCellRangeAddressable)
UnoRuntime.queryInterface(XCellRangeAddressable.class, myRange);
CellRangeAddress myAddr = oRangeAddr.getRangeAddress();
is there a way to format this XCellRange Object so i can specify min , max
and step range for both x and y axis ?
I suggest to use the standard API wherever possible. The developers
guide shows you an example how to access the y axis:
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Charts/Common_Parts_of_all_Chart_Types
Have a look at the idl files and you will find the properties that are
supported by the ChartAxis service:
http://api.openoffice.org/source/browse/api/offapi/com/sun/star/chart/ChartAxis.idl?rev=1.21&view=markup
Min, Max and StepMain are what you are looking for.
2) i got a chart drawn even though i didn't specified the chart type in
below java code .i suppose there is a default charttype in chart2 module
that is used if no other charttype is specified . what is the default
charttype for chart2 module ?
Bar Chart is default. How to change the type is also explained in the
devolopers guide.
3) for chart module i know there are the following charttype services :
"com.sun.star.chart.LineDiagram",
"com.sun.star.chart.BarDiagram",
"com.sun.star.chart.PieDiagram",
"com.sun.star.chart.NetDiagram",
"com.sun.star.chart.XYDiagram",
"com.sun.star.chart.StockDiagram",
"com.sun.star.chart.AreaDiagram"
what are the corresponding charttype services for chart2 module ? i'm
specially interested in CandleStick & Line chart type from chart2 module.
See Daniels mail.
Kind regards,
Ingrid
thanks for your patience & further help.

code :
XSpreadsheet xSheet = //here i get an instance of my XSpreadsheet;
// insert new chart.
// get the CellRange which holds the data for the chart and its
RangeAddress
// get the TableChartSupplier from the sheet and then the
TableCharts from it.
// add a new chart based on the data to the TableCharts.
Rectangle oRect = new Rectangle();
oRect.X = 500;
oRect.Y = 3000;
oRect.Width = 25000;
oRect.Height = 11000;
XCellRange oRange = (XCellRange)UnoRuntime.queryInterface(
XCellRange.class, xSheet);
XCellRange myRange = oRange.getCellRangeByName("A1:E1740");
XCellRangeAddressable oRangeAddr = (XCellRangeAddressable)
UnoRuntime.queryInterface(XCellRangeAddressable.class, myRange);
CellRangeAddress myAddr = oRangeAddr.getRangeAddress();
CellRangeAddress[] oAddr = new CellRangeAddress[1];
oAddr[0] = myAddr;
XTableChartsSupplier oSupp =
(XTableChartsSupplier)UnoRuntime.queryInterface(
XTableChartsSupplier.class, xSheet);
XTableChart oChart = null;
System.out.println("Insert new Chart");
XTableCharts oCharts = oSupp.getCharts();
oCharts.addNewByName("combined chart", oRect, oAddr, true, true);

Hi othman,
Have a look at the developers guides:
Adding a chart to a spreadsheet is explained here including a java
example:
http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Charts/Creating_and_Adding_a_Chart_to_a_Spreadsheet
To get an existing chart within a sheet, look at the same example. Use
the method getByName() at the XTableCharts interface. Where
com.sun.star.chart.XChartDocument is used in the example you can use
com.sun.star.chart2.XChartDocument instead.
Kind regards,
Ingrid

Hi Ingrid,
Sorry i encountered a first problem .
in last email you said:
Ingrid Halama wrote:
Query your chart document for interface
com::sun::star::chart2::XChartDocument
Well I'm not sure how i can get an instance to chart document.
at the beginning there are no charts attached to current spreadsheet .so
should i create an empty com::sun::star::chart2::XChartDocument ?
i'm not sure if i misunderstood your statement . my problem is from where
i
can get an instance to com::sun::star::chart2::XChartDocument . i only
have
reference to current spreadsheet document (XSpreadSheetDocument) .is it
possible to create a new chart document from my spreadsheet document ? if
yes how to do that ?
thanks for helping.
