Area chart has gaps in staircase mode (data specific).

[ESRI]

Here is the code:

static void Main(string[] args)
{
ITChart pChart = new TChartClass();
//pChart.Aspect.View3D = false; //optional
pChart.SetTheme(EChartTheme.ctExcel, EColorPalette.cpExcel); // just to make chart nicer

int idx = pChart.AddSeries(ESeriesClass.scArea); // "area" and "horizontal area" have problem
ISeries pSeries = pChart.Series(idx);
pSeries.XValues.Order = EValueListOrder.loNone; // very important to preserve original data order

IAreaSeries pAreaSeries = pSeries.asArea;
pAreaSeries.Stairs = true; // stairs mode is important to see gaps, without it 2d is ok but 3d will miss one of side walls of the chart
pAreaSeries.AreaPen.Visible = false; // to see gaps better
pAreaSeries.LinePen.Color = 0xff; // to see gaps better

for (int i = 0; i < 7; i++)
//pSeries.AddXY(i, i, null, 0xffffff); // makes correct Area Chart
pSeries.AddXY(6 - i, 6 - i, null, 0xffffff); // makes incorrect Area Chart with gaps

// export graph to observe the problem
IBMPExport pBMP = pChart.Export.asBMP;
pBMP.Height = 250;
pBMP.Width = 600;
pBMP.SaveToFile("c:\\tee_testAreaStairsSortedDesc.bmp");
}

Hi,

yes, you're correct, it's a bug, it does not paint fine with this combination (xorder = loNone and aspect to 3D). I've added on our defect list and a fix for it will be considered to inclusion for the next maintenance releases.

Hola Narcís.

Just wanted to note that we are using TeeChart7.ocx v7.0.1.4, and are still seeing the problem.

Demonstrated here:
