    Creating a Y Plot
    In This Topic

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

    Y Plots : Cartesian, one-dimensional (y-coordinate)

    For details on the API, see the YPlotArea class.

    The following classes are also available:

    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.

    C#
    Copy Code
    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);
    
    VB
    Copy Code
    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.
