PointShape | The shape of individual data elements: 'circle', 'triangle', 'square', 'diamond', 'star', or 'polygon'. |
...
model.addRow("RapidClipse", "7450", 7450);
//Parameter 1 ("RapidClipse"): Wert, welchen in der X-Achse angezeigt werden soll

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. |

area.setTop("100"); //Abstand des Pie von Links in Pixel
area.setChartArea(area);

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

|
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. |

SelectionMode | When selectionMode is 'multiple' , users may select multiple data points. Code Block |
---|
| 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 |
---|
| areaChart.setOrientation(Orientation.HORIZONTAL); |
|
DataOpacity | The transparency of data points, with 1.0 being completely opaque and 0.0 fully transparent. |
