PointShape

The shape of individual data elements: 'circle', 'triangle', 'square', 'diamond', 'star', or 'polygon'.

Code Block
languagejava
themeEclipse

...

model.addItem("RapidClipse", "2015", 6500);

//Parameter 1 ("RapidClipse"): Wert, welchen in der X-Achse angezeigt werden soll
//Parameter 2 ("2015"): Zuweisung zur jeweiligen vorher festgelegten Kategorie (Kategoriemapping)
//Parameter 3 (6500): Wert für die Y-Achse. Zulässige Datentypen: Integer, Double

...

areaChart.setPointShape(PointShape.New(PointShape.Type.CIRCLE));

For detailed informations see: https://developers.google.com/chart/interactive/docs/points

PointSize

Diameter of displayed points in pixels. Use zero to hide all points. You can override values for individual series using the series property. If you're using a trendline, the pointSize option will affect the width of the trendline unless you override it with the trendlines.n.pointsize option.

Code Block
languagejava
themeEclipse

...

XdevAreaChartConfig config = new XdevAreaChartConfig();

final ChartArea area = new ChartArea();

area.setHeigth("100"); //Höhe des Pie
area.setWidth("100"); //Breite des Pie
area.setLeft("100"); //Abstand des Pie von Links in Pixel
area.setRight("100"); //Abstand des Pie von Links in Pixel
area.setTop("100"); //Abstand des Pie von Links in Pixel

config.setChartArea(area);

...

areaChart.setPointSize(5);


PointVisible

Determines whether points will be displayed. Set to false to hide all points.

Code Block
languagejava
themeEclipse

...

XdevAreaChartConfig config = new XdevAreaChartConfig();

//Konfiguration der Punkte
config.setPointShape("circle"); //Form der Punkte. Mögliche Werte: Options.POINTSHAPE_CIRCLE, Options.POINTSHAPE_DIAMOND, Options.POINTSHAPE_POLYGON, Options.POINTSHAPE_SQUARE, Options.POINTSHAPE_STAR, Options.POINTSHAPE_TRIANGLE
config.setPointSize(10); //Größe der Punkte in Pixel

//Konfiguration der Linien
List<Integer> places = Arrays.asList(4,4); //Strichformatierung: Bsp: 4,4 --> 4xMinus 4xLeer Bsp: 4,1,5 --> 4xMinus 4xLeer 5xMinus 4xMinus 4xLeer 5xMinus usw., 
this.config.setLineDashStyle(places);
this.config.setLineWidth(5); //Setzen der Linienbreite
config.setCurveType("function"); //Geschwungene Linien ("function") oder gerade Striche ("none")
areaChart.setPointsVisible(true);


LineDashStyle

The on-and-off pattern for dashed lines. For instance, [4, 4] will repeat 4-length dashes followed by 4-length gaps, and [5, 1, 3] will repeat a 5-length dash, a 1-length gap, a 3-length dash, a 5-length gap, a 1-length dash, and a 3-length gap. See Dashed Lines for more information.

areaChart.setLineDashStyle(Arrays.asList(

...

4,4,4));


LineWidth

Data line width in pixels. Use zero to hide all lines and show only the points. You can override values for individual series using the series property.

Code Block
languagejava
themeEclipse

...

XdevAreaChartConfig config = new XdevAreaChartConfig();

config.setLegend(...); //Siehe API Allgemein "LegendOptions"
config.setTitleTextStyle(...); //Siehe API Allgemein "TextStyle"

config.setFontSize(15); //Setzen allgemeine Schriftgröße im Chart
config.setTitle("Sales Overview"); //Setzen ChartTitel

...

areaChart.setLineWidth(5);


SelectionMode

When selectionMode is 'multiple', users may select multiple data points.

Code Block
languagejava
themeEclipse
areaChart.setSelectionMode(SelectionMode.MULTIPLE);


Orientation

The orientation of the chart. When set to 'vertical', rotates the axes of the chart so that (for instance) a column chart becomes a bar chart, and an area chart grows rightward instead of up:

Code Block
languagejava
themeEclipse
areaChart.setOrientation(Orientation.HORIZONTAL);


DataOpacity

The transparency of data points, with 1.0 being completely opaque and 0.0 fully transparent.

Code Block
languagejava
themeEclipse

...

areaChart.setDataOpacity(0.8);
