Example

This example sets the DropLinesVisible property.

series1.Values.Add(8.0);
series1.Values.Add(12.0);
series1.Values.Add(14.0);
series1.Values.Add(15.0);
FarPoint.Win.Chart.YPlotArea plotArea = new FarPoint.Win.Chart.YPlotArea();
plotArea.Location = new System.Drawing.PointF(0.2f, 0.2f);

labelArea.AlignmentY = 0.0f;
labelArea.Text = "Chart";
FarPoint.Win.Chart.ChartModel model = new FarPoint.Win.Chart.ChartModel();
model.LabelAreas.Add(labelArea);
model.PlotAreas.Add(plotArea);

chart.Size = new Size(200, 200);
chart.Location = new Point(100, 100);
chart.Model = model;
FpSpread1.Sheets[0].Charts.Add(chart);
