Creating PointStyles

PointStyles can easily be created at design time through the PointStyle Collection Editor or programmatically through the PointStyle object.

Creating PointStyles at Design Time

PointStyles can be created at design time using the PointStyle Collection Editor. Using the collection editor, you may add, modify and remove point styles. For more information on the properties in the PointStyle Collection Editor, see PointStyle Collection Editor.

Creating PointStyles Programmatically

The following code creates an instance of PointStyle object and sets its LineStyle and SymbolStyle properties:

· Visual Basic

Dim styles As C1.Win.C1Chart.PointStylesCollection = _

c1Chart1.ChartGroups(0).ChartData.PointStylesList

' min value

Dim psmin As C1.Win.C1Chart.PointStyle = styles.AddNewPointStyle()

psmin.LineStyle.Pattern = C1.Win.C1Chart.LinePatternEnum.None

psmin.SymbolStyle.Color = Color.MistyRose

psmin.SymbolStyle.OutlineColor = Color.Blue

psmin.SymbolStyle.OutlineWidth = 2

psmin.SymbolStyle.Size = 10

psmin.Selection = C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMinY

' show in legend

psmin.Label = "Y Min"

psmin.LegendEntry = True

' max value

Dim psmax As C1.Win.C1Chart.PointStyle = styles.AddNewPointStyle()

psmax.LineStyle.Pattern = C1.Win.C1Chart.LinePatternEnum.None

psmax.SymbolStyle.Color = Color.MistyRose

psmax.SymbolStyle.OutlineColor = Color.Red

psmax.SymbolStyle.OutlineWidth = 2

psmax.SymbolStyle.Size = 10

psmax.Selection = C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMaxY

' show in legend

psmax.Label = "Y Max"

psmax.LegendEntry = True

c1Chart1.Legend.Visible = True

· C#

C1.Win.C1Chart.PointStylesCollection styles = c1Chart1.ChartGroups[0].ChartData.PointStylesList;

// min value

C1.Win.C1Chart.PointStyle psmin = styles.AddNewPointStyle();

psmin.LineStyle.Pattern = C1.Win.C1Chart.LinePatternEnum.None;

psmin.SymbolStyle.Color = Color.MistyRose;

psmin.SymbolStyle.OutlineColor = Color.Blue;

psmin.SymbolStyle.OutlineWidth = 2;

psmin.SymbolStyle.Size = 10;

psmin.Selection = C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMinY;

// show in legend

psmin.Label = "Y Min";

psmin.LegendEntry = true;

// max value

C1.Win.C1Chart.PointStyle psmax = styles.AddNewPointStyle();

psmax.LineStyle.Pattern = C1.Win.C1Chart.LinePatternEnum.None;

psmax.SymbolStyle.Color = Color.MistyRose;

psmax.SymbolStyle.OutlineColor = Color.Red;

psmax.SymbolStyle.OutlineWidth = 2;

psmax.SymbolStyle.Size = 10;

psmax.Selection = C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMaxY;

// show in legend

psmax.Label = "Y Max";

psmax.LegendEntry = true;

c1Chart1.Legend.Visible = true;

· Delphi

var

styles: C1.Win.C1Chart.PointStylesCollection;

psmin: C1.Win.C1Chart.PointStyle;

psmax: C1.Win.C1Chart.PointStyle;

begin

styles := c1Chart1.ChartGroups[0].ChartData.PointStylesList;

// min value

psmin := styles.AddNewPointStyle();

psmin.LineStyle.Pattern := C1.Win.C1Chart.LinePatternEnum.None;

psmin.SymbolStyle.Color := Color.MistyRose;

psmin.SymbolStyle.OutlineColor := Color.Blue;

psmin.SymbolStyle.OutlineWidth := 2;

psmin.SymbolStyle.Size := 10;

psmin.Selection := C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMinY;

// max value

psmax := styles.AddNewPointStyle();

psmax.LineStyle.Pattern := C1.Win.C1Chart.LinePatternEnum.None;

psmax.SymbolStyle.Color := Color.MistyRose;

psmax.SymbolStyle.OutlineColor := Color.Red;

psmax.SymbolStyle.OutlineWidth := 2;

psmax.SymbolStyle.Size := 10;

psmax.Selection := C1.Win.C1Chart.PointStyleSelectionEnum.SeriesMaxY;

c1Chart1.Legend.Visible := true;

end;

PointStyles are added to the data points for the first series of C1Chart. Two special point styles are also added to represent the minimum and maximum value points for the Y-axis.
