XYPlot without vertical axis and horizontal line grid?

问题

Can I draw only vertical data axis (without axis line( in XYPlot and only horizontal line in grid lines (I know the hack - draw them by white color, that is coincident with background color, may be, there is more pure way) ?

回答1:

You can specify currency formatting on the range axis using setNumberFormatOverride(), as shown here.

NumberFormat currency = NumberFormat.getCurrencyInstance();
NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setNumberFormatOverride(currency);

Here is a simple example.

  // create a dataset...
  XYSeries series = new XYSeries("Random Data");
  series.add(1.0, 500.2);
  series.add(10.0, 694.1);

  // Create an XY Line chart
  XYSeriesCollection data = new XYSeriesCollection(series);
  JFreeChart chart = ChartFactory.createXYLineChart("XY Series Demo",
                                                    null,
                                                    "Y",
                                                    data,
                                                    PlotOrientation.VERTICAL,
                                                    true,
                                                    true,
                                                    false);
  XYPlot plot = (XYPlot) chart.getPlot();
  plot.setDomainGridlinesVisible(false);

The vertical lines are hidden by calling plot.setDomainGridLinesVisible(false).
