Y axis groups use same labels when data is in different range

[pfroud]

This code:

public static void main(String[] args) {
     XYChart myChart = new XYChart(800, 600);
     myChart.setTitle("Multiple Y axes scale bug");
     myChart.getStyler().setYAxisGroupPosition(0, Styler.YAxisPosition.Left);
     myChart.getStyler().setYAxisGroupPosition(1, Styler.YAxisPosition.Right);
     myChart.setXAxisTitle("x");
     myChart.setYAxisGroupTitle(0, "group zero");
     myChart.setYAxisGroupTitle(1, "group one");

     myChart.addSeries("series on group zero", new double[]{1, 2, 3}, new double[]{4, 5, 6})
             .setYAxisGroup(0);

     myChart.addSeries("series on group one", new double[]{1, 2, 3}, new double[]{-100, -200, -300})
             .setYAxisGroup(1);

     new SwingWrapper<>(myChart).displayChart();
  }

Produces this chart:

The range of the Y axis on the left (group zero) should be 4 to 6 but actually is 0 to -300.

The expected chart, according to Excel:

The least interesting Excel file ever: expected chart using Microsoft Excel.xlsx

Strange, it works fine for me on the development branch at least. You could use the latest SNAPSHOT jar or wait until the next release which should be soon.

You are right, it works in the development branch!

The Y-axis behavior is correct in release 3.6.5 but wrong in release 3.6.6. I believe the bug was introduced in d0bd425f and fixed in 4bece78d.

OK, thanks. I'll be releasing 3.7.0 by the end of the week hopefully.
