Hi,

I'm having problems importing chart data from XML files.

First I export from an existing chart, which already has properties set

using the API:

    chart1.exportChart(FileFormat.XML,"C:/Documents and

Settings/Administrator/My Documents/exporttest/test.xml");

This seems to produce sensible XML in the correct file location.

Next I try to import the same same file to another chart:

   ChartServer chart2 = new ChartServer(application,request,response );

   chart2.importChart(FileFormat.XML,"C:/Documents and

Settings/Administrator/My Documents/exporttest/test.xml");

This produces the following error:

10:10:32,312 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception

java.lang.NullPointerException

        at SoftwareFX.ChartFX._PointAttributes.Yx(Unknown Source)

        at SoftwareFX.ChartFX._PointAttributes.Vx(Unknown Source)

        at SoftwareFX.ChartFX._SeriesAttributes.$$(Unknown Source)

org.apache.jsp.WEB_002dINF.jsp.constructionChartPanel_jsp._jspService(org.ap

ache.jsp.WEB_002dINF.jsp.constructionChartPanel_jsp:308)

Any help would be much appreciated.

Regards,

Kris

P.S. Some extra info that might help:

Commenting out the second (import) line solves the 'null pointer' exception,

the page displays a 'default' chart.

The following works, using the example from the 'Reading Attributes from

XML' page of the ChartFX guide:

       XMLProvider sfxXml = new XMLProvider();

       sfxXml.load("C:/Documents and Settings/Administrator/My

Documents/exporttest/data.xml");

       chart2.setDataSource(sfxXml);

However, the following produces a blank chart, the binary template being

exported in the usual way:

        XMLProvider sfxXml = new XMLProvider();

       chart2.importChart(FileFormat.BINARY_TEMPLATE,"C:/Documents and

Settings/Administrator/My

Documents/exporttest/bintemp.bin");

       sfxXml.load("C:/Documents and Settings/Administrator/My

Documents/exporttest/data.xml");

       chart2.setDataSource(sfxXml);

Replacing my exported XML with the example from the 'Reading Attributes from

XML' page of the ChartFX guide produces the following (slightly different)

error:

10:27:18,031 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception

java.lang.NullPointerException

Hi Francisco,

I downloaded the latest beta and it seems to have solved my problems.

I am now trying to export DATA to xml. Is this possible? I can do it to a

text file, or using the binary format, but not XML. (I know the manual says

"XML will save only visual attributes", but it's not always 100% correct!).

Regards,

Kris

Dear Kris,

I am sorry but at that this time XML export and import is reserved for 

visual attributes

You pass data to chartfx using the XmlDataProvider but you can't output xml.

We have never really seen a real use case to get data out from the chart but 

perhaps your case is a "real case"?
