Glossary Item Box

You can create an XYZ Plot Chart using code or the designer. The following image shows an XYZPlot point type chart.

XYZ Plots : Point Chart

For details on the API, see the XYZPlotArea class.

The following classes are also available when creating XYZ plot type charts:

Return to the overview at Creating Plot Types.

Using Code

  1. Use the XYZPointSeries class to add data to a Chart control.
  2. Use the XYZPlotArea class to create the 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 using unbound data to create an XYZ point chart.

C# Copy Code 
XYZPointSeries series0 = new XYZPointSeries();
series0.SeriesName = "Series 0";
series0.XValues.Add(1.0);
series0.XValues.Add(2.0);
series0.XValues.Add(4.0);
series0.XValues.Add(8.0);
series0.YValues.Add(2.0);
series0.YValues.Add(4.0);
series0.YValues.Add(3.0);
series0.YValues.Add(5.0);
series0.ZValues.Add(1.0);
series0.ZValues.Add(2.0);
series0.ZValues.Add(1.0);
series0.ZValues.Add(2.0)
XYZPointSeries series1 = new XYZPointSeries();
series1.SeriesName = "Series 1";
series1.XValues.Add(1.0);
series1.XValues.Add(3.0);
series1.XValues.Add(5.0);
series1.XValues.Add(8.0);
series1.YValues.Add(1.0);
series1.YValues.Add(2.0);
series1.YValues.Add(4.0);
series1.YValues.Add(8.0);
series1.ZValues.Add(4.0);
series1.ZValues.Add(3.0);
series1.ZValues.Add(4.0);
series1.ZValues.Add(3.0);
XYZPlotArea plotArea = new XYZPlotArea();

plotArea.Size = new SizeF(0.6f, 0.6f);
plotArea.Series.Add(series0);
plotArea.Series.Add(series1);

label.Text = "XYZ Point Chart";
label.Location = new PointF(0.5f, 0.02f);

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();
