Draw 2 lines with different labels in p:lineChart

[jpessoa]

Hi,

Is it possible to draw, for example, one line with values (2,4), (1,2) and another one with (5,6),(7,8) using p:lineChart?

Thanks in advance,
Jorge Pessoa

I don't see why not

For instance, in primefaces example
cartesianLinerModel = new LineChartModel();
ChartData data = new ChartData();

LineChartDataSet dataSet = new LineChartDataSet();
List<Object> values = new ArrayList<>();
values.add(20);
values.add(50);
values.add(100);
values.add(75);
values.add(25);
values.add(0);
dataSet.setData(values);
dataSet.setLabel("Left Dataset");
dataSet.setYaxisID("left-y-axis");
dataSet.setFill(true);

LineChartDataSet dataSet2 = new LineChartDataSet();
List<Object> values2 = new ArrayList<>();
values2.add(0.1);
values2.add(0.5);
dataSet2.setData(values2);
dataSet2.setLabel("Right Dataset");
dataSet2.setYaxisID("right-y-axis");
dataSet2.setFill(true);

data.addChartDataSet(dataSet);
data.addChartDataSet(dataSet2);

List<String> labels = new ArrayList<>();
labels.add("Jan");
labels.add("Feb");
labels.add("Mar");
labels.add("Apr");
labels.add("May");
labels.add("Jun");
data.setLabels(labels);
cartesianLinerModel.setData(data);

how can i draw 0.1 for Feb and 0.5 for Jun (values2.add(0.1); values2.add(0.5);) (labels.add("Feb");labels.add("Jun");)?

Thanks in advance,

There are 2 lines drawn on the Showcase? https://www.primefaces.org/showcase/ui/ ... line.xhtml Can't you look at that?
