Chart classes should have secondary constructors to support hierarchical building pattern

[GoogleCodeExporter]

Most of the chart classes do not have secondary constructors. This prevents use 
of the hierarchical building pattern. For instance, when creating BarChart we 
currently have to address properties through a variable holding the chart:

  val barChart1 = BarChart(new CategoryAxis(), new NumberAxis())
  barChart1.title = "Speculations"
  barChart1.data = createChartData(data1)
  barChart1.legendVisible = false
  barChart1.onMouseClicked = showInTable(barChart1.title(), data1)

With a secondary constructor taking axis as arguments (corresponding to similar 
delegate constructor) we could use hierarchical building pattern:

  val barChart1 = new BarChart(new CategoryAxis(), new NumberAxis()) {
    title = "Speculations"
    data = createChartData(data1)
    legendVisible = false
    onMouseClicked = showInTable(title(), data1)
  }

Secondary constructors, corresponding to delegate constructors, should be added 
for all chart classes.
