You can create a Y Plot Chart using code or the designer. The following image shows a YPlot bar type chart.

For details on the API, see the YPlotArea class.

The following classes are also available:

• YSeries
• BarSeries
• AreaSeries
• LineSeries
• PointSeries
• HighLowAreaSeries
• HighLowBarSeries
• HighLowCloseSeries

Using Code

1. Use the BarSeries class to add data to a Chart control.
2. Use the YPlotArea class to create a plot area.
3. Set the location and size of the plot area.
4. Add the series to the plot area.
5. Create a label and legend for the chart.
6. Create a chart model and add the plot area, label, and legend to the model.
7. Create a chart and add the chart model to it.
8. Add the chart to the Spread control.

Example

The following example demonstrates creating a Y Plot chart and adding unbound data to the control.

BarSeries series = new BarSeries();
series.SeriesName = "Series 0";
series.Values.Add(2.0);
series.Values.Add(4.0);
series.Values.Add(3.0);
series.Values.Add(5.0);
YPlotArea plotArea = new YPlotArea();
plotArea.Location = new PointF(0.2f, 0.2f);
plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series);
LabelArea label = new LabelArea();
label.Text = "Bar Chart";
label.Location = new PointF(0.5f, 0.02f);
label.AlignmentX = 0.5f;
label.AlignmentY = 0.0f;
LegendArea legend = new LegendArea();
legend.Location = new PointF(0.98f, 0.5f);
legend.AlignmentX = 1.0f;
legend.AlignmentY = 0.5f;
ChartModel model = new ChartModel();
model.LabelAreas.Add(label);
model.LegendAreas.Add(legend);
model.PlotAreas.Add(plotArea);
FarPoint.Web.Spread.Chart.SpreadChart chart = new FarPoint.Web.Spread.Chart.SpreadChart();
chart.Model = model;
FpSpread1.Sheets[0].Charts.Add(chart);

Dim series As New FarPoint.Web.Chart.BarSeries()
series.SeriesName = "Series 0"
series.Values.Add(2.0)
series.Values.Add(4.0)
series.Values.Add(3.0)
series.Values.Add(5.0)
Dim plotArea As New FarPoint.Web.Chart.YPlotArea()
plotArea.Location = New PointF(0.2F, 0.2F)
plotArea.Size = New SizeF(0.6F, 0.6F)
plotArea.Series.Add(series)
Dim label As New FarPoint.Web.Chart.LabelArea()
label.Text = "Bar Chart"
label.Location = New PointF(0.5F, 0.02F)
label.AlignmentX = 0.5F
label.AlignmentY = 0.0F
Dim legend As New FarPoint.Web.Chart.LegendArea()
legend.Location = New PointF(0.98F, 0.5F)
legend.AlignmentX = 1.0F
legend.AlignmentY = 0.5F
Dim model As New FarPoint.Web.Chart.ChartModel()
model.LabelAreas.Add(label)
model.LegendAreas.Add(legend)
model.PlotAreas.Add(plotArea)
Dim chart As New FarPoint.Web.Spread.Chart.SpreadChart()
chart.Model = model
FpSpread1.Sheets(0).Charts.Add(chart)

Using the Chart Designer

1. Select the PlotArea Collection editor.
2. Set properties as needed.
3. Select Apply and OK to close the Chart Designer.
