Hi,

I was trying to update my project Nevron references from Q1 2007 to Q1 2012. However, I confronted a scale problem. So I tried to update references one-by-one and found the version causing it.

Problem Definition:
In my project with Q1 2012 I have seen that polar charts are displayed as compressed in default small view with respect to Q1 2007. When I enlarge the view by dragging the edge of view, it looks like normal as in Q1 2007. Thus, I have written a sample code and tested it. Here is the possible problem:

I want to display my polar chart as the chart in 'Sample Q2 2008.png'.
Hovewer, when I upgrade the version to Q3 2008, I have to use NPolarAreaSeries. If I don't change my linearScaleConfigurator, chart is displayed as in 'Sample Q3 LinearScaler 2008.png'. Why is it smaller than the previous version display?
Moreover, when I use NAngularScaleConfigurator, chart is displayed as in 'Sample Q3 AngularScaler 2008.png'. Why is it compressed?

The code below is the sample code that produced displays in the attachments.

Code :
public Form()
{
InitializeComponent();

NLabel header = nChartControl1.Labels.AddHeader("Polar Area");
header.TextStyle.FontStyle = new NFontStyle("Times New Roman", 18, FontStyle.Italic);
header.ContentAlignment = ContentAlignment.BottomRight;
header.Location = new NPointL(new NLength(2, NRelativeUnit.ParentPercentage), new NLength(2, NRelativeUnit.ParentPercentage));

NPolarChart polarChart = new NPolarChart();

nChartControl1.Charts.Clear();
nChartControl1.Charts.Add(polarChart);

polarChart.DisplayOnLegend = nChartControl1.Legends[0];

NAxis axisX = polarChart.Axis(Nevron.Chart.StandardAxis.Polar);
axisX.Visible = this.Visible;

//axisX.ScaleConfigurator = new Nevron.Chart.NAngularScaleConfigurator();
//((Nevron.Chart.NAngularScaleConfigurator)axisX.ScaleConfigurator).LabelStyle.Angle = new Nevron.Chart.NScaleLabelAngle(Nevron.Chart.ScaleLabelAngleMode.View, 0);
axisX.ScaleConfigurator = new Nevron.Chart.NLinearScaleConfigurator();
((Nevron.Chart.NLinearScaleConfigurator)axisX.ScaleConfigurator).LabelStyle.Angle = new Nevron.Chart.NScaleLabelAngle(0);

NAxis axisY = polarChart.Axis(Nevron.Chart.StandardAxis.Polar);
axisY.Visible = this.Visible;

//axisY.ScaleConfigurator = new Nevron.Chart.NAngularScaleConfigurator();
//((Nevron.Chart.NAngularScaleConfigurator)axisY.ScaleConfigurator).LabelStyle.Angle = new Nevron.Chart.NScaleLabelAngle(Nevron.Chart.ScaleLabelAngleMode.View, 0);
axisY.ScaleConfigurator = new Nevron.Chart.NLinearScaleConfigurator();
((Nevron.Chart.NLinearScaleConfigurator)axisY.ScaleConfigurator).LabelStyle.Angle = new Nevron.Chart.NScaleLabelAngle(0);

NPolarAreaSeries polarAreaSeries = new NPolarAreaSeries();
//NPolarSeries polarAreaSeries = new NPolarSeries();
//polarAreaSeries.Style = Nevron.Chart.PolarStyle.FilledArea;

polarChart.Series.Add(polarAreaSeries);

polarAreaSeries.HorizontalAxes = new int[] { axisX.AxisId };
polarAreaSeries.VerticalAxes = new int[] { axisY.AxisId };

polarAreaSeries.FillStyle = new Nevron.GraphicsCore.NColorFillStyle(Color.LightSteelBlue);
polarAreaSeries.MarkerStyle = new NMarkerStyle();
polarAreaSeries.MarkerStyle.PointShape = PointShape.Sphere;
polarAreaSeries.MarkerStyle.Width = new NLength(5);
polarAreaSeries.MarkerStyle.Visible = true;
polarAreaSeries.Name = "asdasdasd";
polarAreaSeries.DataLabelStyle.Visible = false;

GenerateData(polarAreaSeries, 100, 15.0);
}

private void GenerateData(NPolarSeries series, int count, double scale)
{
series.Values.Clear();
series.Angles.Clear();

double angleStep = 2 * Math.PI / count;

for (int i = 0; i < count; i++)
{
double angle = i * angleStep;
double c1 = 1.0 * Math.Sin(angle * 3);
double c2 = 0.3 * Math.Sin(angle * 1.5);
double c3 = 0.05 * Math.Cos(angle * 26);
//double c4 = 0.05 * (0.5 - Random.NextDouble());
double value = scale * (Math.Abs(c1 + c2 + c3));

if (value < 0)
value = 0;

series.Values.Add(value);
series.Angles.Add(angle * 180 / Math.PI);
}
}
}

Hi Ismet,

Newer versions of the control fit the polar chart (as well as all other charting types) inside the box defined by its panel. To make the chart larger you need to simply increase the chart panel size. Let us know if you have any questions or meet any problems.
