I have a radial gauge in my application. It's appears on the rectangular panel which has a black one-pixel border.

This is the code:


NChartControl nChartControl = container as NChartControl;

m_RadialGauge = new NRadialGaugePanel();
_gauge = m_RadialGauge;

m_RadialGauge.BorderStyle = new NEdgeBorderStyle(BorderShape.Auto);
m_RadialGauge.ContentAlignment = ContentAlignment.MiddleCenter;
m_RadialGauge.Location = new NPointL(new NLength(50, NRelativeUnit.ParentPercentage), new NLength(50, NRelativeUnit.ParentPercentage));
m_RadialGauge.Size = new NSizeL(new NLength(90, NRelativeUnit.ParentPercentage), new NLength(90, NRelativeUnit.ParentPercentage));
m_RadialGauge.BackgroundFillStyle = new NColorFillStyle(Color.Black);

NGaugeAxis axis = (NGaugeAxis)m_RadialGauge.Axes[0];
axis.Anchor = new NDockGaugeAxisAnchor(GaugeAxisDockZone.Top, true, RulerOrientation.Right, 0, 100);

createRangeIndicators(m_RadialGauge);
...
nChartControl.Panels.Add(m_RadialGauge);


Is it possible to hide this black border?
