API und Methoden:

...

...

Properties
PointShape	The shape of individual data elements: 'circle', 'triangle', 'square', 'diamond', 'star', or 'polygon'. Code Block language java theme Eclipse

...

model.addXCategory("Year");

//Parameter 1 ("Year"): definiert die Beschriftung der X-Achse

model.addYCategory("RapidClipse");
model.addYCategory("XDEV 5");

//Parameter 1 ("RapidClipse"): definiert die Beschriftung und wird als Mapping Parameter und Gruppierung verwendet wird

...

lineChart.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 language java theme Eclipse

...

model.addItem("RapidClipse", "2013", 4500);

//Parameter 1 ("RapidClipse"): Wert, welchen in der X-Achse angezeigt werden soll
//Parameter 2 ("2013"): Zuweisung zur jeweiligen vorher festgelegten Kategorie (Kategoriemapping)
//Parameter 3 (4500): Wert für die Y-Achse. Zulässige Datentypen: Integer, Double

lineChart.setPointSize(5);
PointVisible	Determines whether points will be displayed. Set to false to hide all points. Code Block language java theme Eclipse

...

XdevLineChartConfig config = new XdevLineChartConfig();

config.setOrientation(Options.ORIENTATION_VERTICAL); //Ausrichtung des Charts. Mögliche Werte: Options.ORIENTATION_VERTICAL, Options.ORIENTATION_HORIZONTAL

...

lineChart.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. Code Block language java theme Eclipse

...

lineChart.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 language java theme Eclipse lineChart.setLineWidth(5);
CurveType	Controls the curve of the lines when the line width is not zero. Can be one of the following: Code Block language java theme Eclipse

...

XdevLineChartConfig config = new XdevLineChartConfig();

final ChartArea area = new ChartArea();

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

config.setChartArea(area);

...

lineChart.setCurveType(CurveType.FUNCTION);
SelectionMode	When selectionMode is 'multiple', users may select multiple data points. Code Block language java theme Eclipse

...

XdevLineChartConfig config = new XdevLineChartConfig();

config.setBackgroundColor(...); //Siehe API Allgemein "BackgroundStyle"

//Eine Liste an Farben die dann der Reihe nach an die Kategorien vergeben werden
List<String> places = Arrays.asList("#FFFFFF", "Red", "#F4g6uz");
config.setColors(places); //Zuweisen der Farbliste

...

lineChart.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 language java theme Eclipse

...

XdevLineChartConfig config = new XdevLineChartConfig();

config.setLegend(...); //Siehe API Allgemein "LegendOptions"
config.setTitleTextStyle(...); //Siehe API Allgemein "TextStyle"
config.setFontName(""); //Wahl der Schriftart (Schriftart muss vom Browser unterstützt werden)
config.setFontSize(15); //Setzen allgemeine Schriftgröße im Chart
config.setTitle("Sales Overview"); //Setzen ChartTitel

...

lineChart.setOrientation(Orientation.HORIZONTAL);
DataOpacity	The transparency of data points, with 1.0 being completely opaque and 0.0 fully transparent. Code Block language java theme Eclipse

...

lineChart.setCurveType(CurveType.FUNCTION);
