Hi,

We intend to make heavy use of the XML functionality of the chart control. However for many chart styles, for example bar, bubble..., when the xml is saved there is no fill information. When reloaded , the chart does not have any colour fill.

Is this a bug or is there something to do to save that information?

We have modified the chart browser sample to save the xml as follows:

void CBaseView::OnFileSave()

{

CFileDialog dlg(FALSE);

if (dlg.DoModal() != IDOK)

return;

CXTPPropExchangeXMLNode px(FALSE, NULL, _T("Content"));

CXTPChartContent* pContent = m_wndChartControl.GetContent();

pContent->DoPropExchange(&px);

CFile file;

if (!file.Open(dlg.GetPathName(), CFile::modeWrite | CFile::modeCreate))

return;

USES_CONVERSION;

CStringA sXML = W2A(px.GetEncodedXML(TRUE));

file.Write(sXML.GetBuffer(), sXML.GetLength());

}

And when we load this, for example the bar chart, here is what we get:

Looking at differences between the xml in resources of the chartbrowser sample and what is returned by the code, the bug is that in the generated XML it generates:

But the chart control only understands:

<FillStyle FillMode="Gradient" GradientDirection="BottomRightToTopLeft"/>
