CBCGPChartLegendEntry

Detailed Description

The CBCGPChartLegendEntry class implements the functionality of legend row and manages a list of CBCGPChartLegendCell objects.

If you wish to add one or more custom cells displayed in one row, you have to override CBCGPChartLegendVisualObject::OnLegendContentCreated or process BCGM_ON_CHART_LEGEND_CONTENT_CREATED, create a legend entry, create custom cells with desired content, add cells to entry and finally add entry to legend.

The following example illustrates how to add an entry (legend row) with two custom cells at the top of the legend:

Copy

LRESULT CMyView::OnLegendContentCreated(WPARAM, LPARAM lp)

{

CBCGPChartLegendVisualObject* pLegend = (CBCGPChartLegendVisualObject*)lp;

CBCGPChartLegendEntry* pEntryHead = new CBCGPChartLegendEntry(pLegend);

CBCGPChartLegendCell* pCell1 = new CBCGPChartLegendCell(_T("Head Item"));

CBCGPChartLegendCell* pCell2 = new CBCGPChartLegendCell(_T("Head Value"));

pEntryHead->AddLegendCell(pCell1);

pEntryHead->AddLegendCell(pCell2);

pLegend->InsertLegendEntry(pEntryHead, 0);

return 0;
