API und Methoden:
...
| Properties |
|
|---|
| PointShape | The shape of individual data elements: 'circle', 'triangle', 'square', 'diamond', 'star', or 'polygon'. |
...
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. |
...
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, DoublelineChart.setPointSize(5); |
|
| PointVisible | Determines whether points will be displayed. Set to false to hide all points. |
...
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. |
...
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 |
|---|
| lineChart.setLineWidth(5); |
|
| CurveType | Controls the curve of the lines when the line width is not zero. Can be one of the following: |
...
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. |
...
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: |
...
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. |
...
lineChart.setCurveType(CurveType.FUNCTION); |
