# Creating a Polar Plot

Learn how to create a Polar Plot chart using code or the designer with detailed API information and examples.

## Content

You can create a polar plot chart using code or the designer. The following image shows a Polar Plot type chart.

For details on the API, see the [PolarPlotArea](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarPlotArea.html) class. The following classes are also available when creating Polar plot type charts:

* Point chart (scatter plot)
    [PolarPointSeries](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarPointSeries.html)
* Line Chart
    [PolarLineSeries](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarLineSeries.html)
* Area Chart
    [PolarAreaSeries](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarAreaSeries.html)

In addition, value axes such as ruler lines, memory, and scale labels are set using the following classes.

* [PolarAngleAxis](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarAngleAxis.html)
* [PolarRadiusAxis](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarRadiusAxis.html)

## Using Code

1. Create a [PolarPointSeries](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarPointSeries.html) object that represents the data series for the circle chart and add the data.
2. Use the [PolarPlotArea](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.PolarPlotArea.html) class to create the plot area.
3. Add the series to the plot area.
4. Create a label and legend for the chart.
5. Create a [ChartModel](/spreadnet/api/latest/online-win/FarPoint.Win.Chart/FarPoint.Win.Chart.ChartModel.html) object and add the plot area, label, and legend to the model.
6. Create a chart and add the chart model to it.

## Example

The following example demonstrates creating a polar point series chart.

```csharp
FarPoint.Win.Chart.PolarPointSeries series0 = new FarPoint.Win.Chart.PolarPointSeries();
series0.SeriesName = "Series 0";
series0.XValues.Add(0.0);
series0.XValues.Add(45.0);
series0.XValues.Add(90.0);
series0.XValues.Add(180.0);
series0.XValues.Add(270.0);
series0.YValues.Add(1.0);
series0.YValues.Add(2.0);
series0.YValues.Add(3.0);
series0.YValues.Add(4.0);
series0.YValues.Add(5.0);
FarPoint.Win.Chart.PolarPointSeries series1 = new FarPoint.Win.Chart.PolarPointSeries();
series1.SeriesName = "Series 1";
series1.XValues.Add(0.0);
series1.XValues.Add(45.0);
series1.XValues.Add(90.0);
series1.XValues.Add(180.0);
series1.XValues.Add(270.0);
series1.YValues.Add(2.0);
series1.YValues.Add(3.0);
series1.YValues.Add(4.0);
series1.YValues.Add(5.0);
series1.YValues.Add(6.0);
FarPoint.Win.Chart.PolarPlotArea plotArea = new FarPoint.Win.Chart.PolarPlotArea();
plotArea.Location = new PointF(0.2f, 0.2f);
plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series0);
plotArea.Series.Add(series1);
FarPoint.Win.Chart.LabelArea label = new FarPoint.Win.Chart.LabelArea();
label.Text = "Polar Point Chart";
label.Location = new PointF(0.5f, 0.02f);
label.AlignmentX = 0.5f;
label.AlignmentY = 0.0f;
FarPoint.Win.Chart.LegendArea legend = new FarPoint.Win.Chart.LegendArea();
legend.Location = new PointF(0.98f, 0.5f);
legend.AlignmentX = 1.0f;
legend.AlignmentY = 0.5f;
FarPoint.Win.Chart.ChartModel model = new FarPoint.Win.Chart.ChartModel();
model.LabelAreas.Add(label);
model.LegendAreas.Add(legend);
model.PlotAreas.Add(plotArea);
chart2DControl1.Model = model;
```

```vbnet
Dim series0 As New FarPoint.Win.Chart.PolarPointSeries()
series0.SeriesName = "Series 0"
series0.XValues.Add(0.0)
series0.XValues.Add(45.0)
series0.XValues.Add(90.0)
series0.XValues.Add(180.0)
series0.XValues.Add(270.0)
series0.YValues.Add(1.0)
series0.YValues.Add(2.0)
series0.YValues.Add(3.0)
series0.YValues.Add(4.0)
series0.YValues.Add(5.0)
Dim series1 As New FarPoint.Win.Chart.PolarPointSeries()
series1.SeriesName = "Series 1"
series1.XValues.Add(0.0)
series1.XValues.Add(45.0)
series1.XValues.Add(90.0)
series1.XValues.Add(180.0)
series1.XValues.Add(270.0)
series1.YValues.Add(2.0)
series1.YValues.Add(3.0)
series1.YValues.Add(4.0)
series1.YValues.Add(5.0)
series1.YValues.Add(6.0)
Dim plotArea As New FarPoint.Win.Chart.PolarPlotArea()
plotArea.Location = New PointF(0.2F, 0.2F)
plotArea.Size = New SizeF(0.6F, 0.6F)
plotArea.Series.Add(series0)
plotArea.Series.Add(series1)
Dim label As New FarPoint.Win.Chart.LabelArea()
label.Text = "Polar Point Chart"
label.Location = New PointF(0.5F, 0.02F)
label.AlignmentX = 0.5F
label.AlignmentY = 0F
Dim legend As New FarPoint.Win.Chart.LegendArea()
legend.Location = New PointF(0.98F, 0.5F)
legend.AlignmentX = 1.0F
legend.AlignmentY = 0.5F
Dim model As New FarPoint.Win.Chart.ChartModel()
model.LabelAreas.Add(label)
model.LegendAreas.Add(legend)
model.PlotAreas.Add(plotArea)
chart2DControl1.Model = model
```

## Using the Chart designer

1. Run **Chart Designer**.
2. Select the target **Chart Model** from the tree menu on the left.
3. Open the **Plot Area Collection Editor** from PlotAreas in the **Other** section of the property list on the right.
4. Click the drop-down button to the right of the **Add** button.
5. Select and add the **PolarPlotArea** and set each property as required.
