Stacked Charts - oliverwatkins/Iceberg-Charts GitHub Wiki
It is possible to vertically stack charts if they share the same X-Axis using a StackedXYChart.
The following example creates three seperate charts, and creates an x-axis which is then shared across all three charts. Additionally three percentage values are passed in as an array to give the various percentage heights of the three charts :
//x-Axis needs to be shared
XAxis xAxis = new XAxis(new LinearNumericalAxisScalingX(), "X");
xAxis.axisScaling.setMinValue(0);
xAxis.axisScaling.setMaxValue(100);
XYChart topChart = (XYChart)new TestDataBar_5_PosNegColor().getChart();
topChart.xAxis = xAxis;
XYChart bottomChart = (XYChart)new TestDataXY_SineCurve().getChart();
bottomChart.xAxis = xAxis;
XYChart middleChart = (XYChart)new TestDataXY_Scatter().getChart();
middleChart.xAxis = xAxis;
ArrayList<XYChart> charts = new ArrayList<XYChart>();
charts.add(topChart);
charts.add(middleChart);
charts.add(bottomChart);
//height percentages
ArrayList<Integer> percentages = new ArrayList<Integer>();
percentages.add(40);
percentages.add(30);
percentages.add(30);
StackedXYChart stackedXYChart = new StackedXYChart("Three random charts with same X Axis", charts, percentages);
The application of stacked charts is particularly common in the finance world. For example candle stick charts combined with a bar chart :
