Certain chart properties are not exported to XML files

Hi,

I'm using ChartFX for Java 6.2 (Version 6.2.2266.27659) and I'm having 

issues with exporting and re-importing a chart.

Not all properties are written to the exported XML file, despite I'm 

explicitly set the fileMask to ALL.

The following snippet shows how I'm creating a chart, setting some 

properties and export it to an PNG file as well as an XML template.

Chart c = new Chart();

c.setGallery(Gallery.SCATTER);

TextProvider txtProvider = new TextProvider("data.txt");

txtProvider.setSeparators(";");

c.setDataType(0, DataType.XVALUE);

c.setDataType(1, DataType.VALUE);

c.getAxisX().getLabelsFormat().setFormat(AxisFormat.DATE);

c.setDataSource(txtProvider);

c.setSerLegBox(true);

c.getAxisY().getTitle().setText("Title");		

c.getSeries(0).setGallery(Gallery.LINES);

c.setWidth(1024);

c.setHeight(640);

try {

   c.setFileMask(c.getFileMask() | FileMask.ALL | FileMask.DATA_BIND);

   c.exportChart(FileFormat.PNG,"image.png");

   c.exportChart(FileFormat.XML,"chart.xml");

} catch (IOException e) {

   e.printStackTrace();

}

The PNG is rendered correctly, but the XML doesn't contain any entries 

for the width and the height of the chart (nor any data, despite ALL 

should include data, right?).

Hence if the XML is re-imported, the chart has the default dimensions.

Chart c2 = new Chart();

c2.setFileMask(FileMask.ALL);

try {

   c2.importChart(FileFormat.XML,"chart.xml");

   TextProvider txtProvider = new TextProvider("data.txt");

   txtProvider.setSeparators(";");

   txtProvider.setDateFormat("yyyy/MM/dd");

   c2.setDataSource(txtProvider);

   c2.exportChart(FileFormat.PNG,"image_reimport.png");

} catch (IOException e) {

   e.printStackTrace();

}

The file image_reimport.png differs in size from image.png.

What could I possibly miss? I've checked the exported XML, and as said 

before, there are no <WIDTH> or <HEIGHT> entries. If they are manually 

added before re-importing the chart, they wouldn't affect the size neither.

What could be the reason for that issue? Am I miss something obvious 

here? Why is the chart data not exported as well? The documentation 

states that FileFormat.ALL contains everything and is valid for XML export.

Thanks for any help in advance,

	Kurt

Hi,

Chart c = new Chart();

c.setGallery(Gallery.SCATTER);

TextProvider txtProvider = new TextProvider("data.txt");

txtProvider.setSeparators(";");

c.setDataType(0, DataType.XVALUE);

c.setDataType(1, DataType.VALUE);

c.getAxisX().getLabelsFormat().setFormat(AxisFormat.DATE);

c.setDataSource(txtProvider);

c.setSerLegBox(true);

c.getAxisY().getTitle().setText("Title");		

c.getSeries(0).setGallery(Gallery.LINES);

c.setWidth(1024);

c.setHeight(640);

try {

   c.setFileMask(c.getFileMask() | FileMask.ALL | FileMask.DATA_BIND);

   c.exportChart(FileFormat.PNG,"image.png");

   c.exportChart(FileFormat.XML,"chart.xml");

} catch (IOException e) {

   e.printStackTrace();

}

The PNG is rendered correctly, but the XML doesn't contain any entries 

for the width and the height of the chart (nor any data, despite ALL

Chart c2 = new Chart();

c2.setFileMask(FileMask.ALL);

try {

   TextProvider txtProvider = new TextProvider("data.txt");

   txtProvider.setSeparators(";");

   txtProvider.setDateFormat("yyyy/MM/dd");

   c2.setDataSource(txtProvider);

   c2.exportChart(FileFormat.PNG,"image_reimport.png");

} catch (IOException e) {

   e.printStackTrace();

}

The file image_reimport.png differs in size from image.png.

The  <WIDTH> and <HEIGHT> are not included whe you export to XML or Binary. 

This is by design, and we are going to change it for future versions.
