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

...

model.addItem("Beverages", "2017", 560);

//Parameter 1 ("Beverages"): Wert, welchen in der X-Achse angezeigt werden soll
//Parameter 2 ("2017"): Zuweisung zur jeweiligen vorher festgelegten Kategorie (Kategoriemapping)
//Parameter 3 (530): Wert für die Y-Achse. Zulässige Datentypen: Integer, Double,

StackMode

The options for isStacked are:

  • false — elements will not stack. This is the default option.
  • true — stacks elements for all series at each domain value.
  • 'percent' — stacks elements for all series at each domain value and rescales them such that they add up to 100%, with each element's value calculated as a percentage of 100%.
  • 'relative' — stacks elements for all series at each domain value and rescales them such that they add up to 1, with each element's value calculated as a fraction of 1.
  • 'absolute' — functions the same as isStacked: true.
Code Block
languagejava
this.barChart.setStackMode(StackMode.TRUE);
