setXAxisMin(0.0) and setYAxisMin(0.0) not working properly?

[Perneel]

I'm creating a XYChart. I have set the following:

chart.getStyler().setXAxisMin(0.0);
chart.getStyler().setYAxisMin(0.0);

This is the result:

Shouldn't be the point at 0.0 in the lower left corner? Or am I missing a padding or margin somewhere?

Can you paste here a full Java class producing the above plot please?

As requested:

           // Create Chart
            XYChart chart = new XYChartBuilder()
                    .width(500)
                    .height(350)
                    .theme(ChartTheme.Matlab)
                    .build();

            // Series
            .....
            chart.addSeries("Serie1", xData1, yData1);
            chart.addSeries("Serie2", xData2, yData2);
            XYSeries vertical = chart.addSeries("vertical", new double[]{5, 5}, new double[]{0, 10});
            vertical.setShowInLegend(false);
            vertical.setXYSeriesRenderStyle(XYSeriesRenderStyle.Line);
            vertical.setLineStyle(SeriesLines.SOLID);
            XYSeries horizontal = chart.addSeries("horizontal", new double[]{0, 10}, new double[]{5, 5});
            horizontal.setShowInLegend(false);
            horizontal.setXYSeriesRenderStyle(XYSeriesRenderStyle.Line);
            horizontal.setLineStyle(SeriesLines.SOLID);

            // Customize Chart
            Marker[] markers = {SeriesMarkers.SQUARE, SeriesMarkers.SQUARE, SeriesMarkers.DIAMOND, SeriesMarkers.DIAMOND};
            Color[] colors = {Color.GRAY, Color.BLUE, Color.RED, Color.RED};

            chart.getStyler().setDefaultSeriesRenderStyle(XYSeriesRenderStyle.Scatter);
            chart.getStyler().setLegendPosition(LegendPosition.OutsideE);
            chart.getStyler().setMarkerSize(5);
            chart.getStyler().setAxisTicksVisible(false);
            chart.getStyler().setXAxisMin(0.0);
            chart.getStyler().setYAxisMin(0.0);
            chart.getStyler().setSeriesMarkers(markers);
            chart.getStyler().setSeriesColors(colors);
            chart.getStyler().setPlotGridLinesVisible(false);

It's working fine I believe. First without min/max, second is with.

  public static void main(String[] args) {

    // Create Chart
    XYChart chart = new XYChartBuilder()

    int size = 1000;
    for (int i = 0; i < size; i++) {
      xData.add(5 * random.nextGaussian());
      yData.add(5 * random.nextGaussian());
    }
    chart.addSeries("Gaussian Blob", xData, yData);

    XYSeries vertical = chart.addSeries("vertical", new double[]{5, 5}, new double[]{0, 10});
    vertical.setShowInLegend(false);
    vertical.setXYSeriesRenderStyle(XYSeries.XYSeriesRenderStyle.Line);

    horizontal.setShowInLegend(false);

    chart.getStyler().setPlotGridLinesVisible(false);

    new SwingWrapper<XYChart>(chart).displayChart();
  }
}

Hm it's still not totally clear to me, I took the example of your screenshot with the min/max applied:

Shouldn't the light blue lines be the axis? Or am I missing something? :) Or is this caused by the Theme? That it doesn't show the axis, only the plotted box?

[timmolter]

Yes, that's 0,0. Set chart.getStyler().setAxisTicksVisible(true); and you will see.

[Perneel]

Aha I see... is there a possibility to show the axis actually on the 0.0 point?

[timmolter]

try chart.getStyler().setPlotContentSize(1.0);

[Perneel]

jep that's what I was looking for, thanks a lot!
