getBarChartView with RangeCategorySeries not display value with min positive #364

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?
When i build a graphicView with a RangeCAtegory if the min value is under zero 
and max is positive everything works fine. if both are positive (min and max) 
and min > max the column of graph start by zero and not by min value

What is the expected output? What do you see instead?
See the attachment file for output

Please provide a source code snippet that we can use to replicate the
issue.
double[] minValues = new double[] { -24, -19, -10, -1, 7, 12, 15, 14, 9, 1, 
-11, -16 };
    double[] maxValues = new double[] { 7, 12, 24, 28, 33, 35, 37, 36, 28, 19, 11, 4 };

    XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();
    RangeCategorySeries series = new RangeCategorySeries("Temperature");
    int length = minValues.length;
    for (int k = 0; k < length; k++) {
      series.add(minValues[k], maxValues[k]);
    }
    dataset.addSeries(series.toXYSeries());
    int[] colors = new int[] { Color.CYAN };
    XYMultipleSeriesRenderer renderer = buildBarRenderer(colors);
    setChartSettings(renderer, "Monthly temperature range", "Month", "Celsius degrees", 0.5, 12.5,
        -30, 45, Color.GRAY, Color.LTGRAY);
    renderer.setBarSpacing(0.5);
    renderer.setXLabels(0);
    renderer.setYLabels(10);
    renderer.addXTextLabel(1, "Jan");
    renderer.addXTextLabel(3, "Mar");
    renderer.addXTextLabel(5, "May");
    renderer.addXTextLabel(7, "Jul");
    renderer.addXTextLabel(10, "Oct");
    renderer.addXTextLabel(12, "Dec");
    renderer.addYTextLabel(-25, "Very cold");
    renderer.addYTextLabel(-10, "Cold");
    renderer.addYTextLabel(5, "OK");
    renderer.addYTextLabel(20, "Nice");
    renderer.setMargins(new int[] {30, 70, 10, 0});
    renderer.setYLabelsAlign(Align.RIGHT);
    SimpleSeriesRenderer r = renderer.getSeriesRendererAt(0);
    r.setDisplayChartValues(true);
    r.setChartValuesTextSize(12);
    r.setChartValuesSpacing(3);
    r.setGradientEnabled(true);
    r.setGradientStart(-20, Color.BLUE);
    r.setGradientStop(20, Color.GREEN);
    GraphicalView gw = ChartFactory.getBarChartView(context, dataset, renderer, Type.DEFAULT);
