API and methods

Properties

Title

Calendar title

this.calendarChart.setTitle("Ich bin ein Titel");

NoDataPattern

Calendar charts use a striped diagonal pattern to indicate that there is no data for a given day. Use the noDataPattern.backgroundColor and noDataPattern.color options to override the grayscale defaults, e.g.:

this.calendarChart.setNoDataPattern(NoDataPattern.New("white", "white"));

Calendar

The Calendar object is a multi-attribute object to configure the style of the calendar

this.calendarChart.setCalendar(Calendar.Builder()
    .cellColor(CellColor.New("gray"))
    .cellSize(50)
    .dayOfWeekLabel(TextStyle.New("green"))
    .dayOfWeekRightSpace(50)
    .daysOfWeek("SMDMDFS")
    .monthLabel(TextStyle.New("red"))
    .underMonthSpace(20)
    .build());
