LogarithmicAxis assistance - blew away the test code :(

[Guest]

Hello all-

First time poster but I did buy the docs.

I wrote some test code to do a Logarithmic Axis on the Y-Axis... and then blew it away in clearcase. For the life of me I have not been able to duplicate however I did it, and I haven't found my references to try.

Can anyone point me in the right direction? This is driving me insane.

Thanks in advance,

Jason Hirsch

hello,do u want this?

Code: Select all

    private JFreeChart createChart(XYDataset dataset) {

        JFreeChart chart = ChartFactory.createXYLineChart(
            "XY Line Chart Test", // chart title
            "X", // x axis label
            "Y", // y axis label
            dataset, // data
            PlotOrientation.VERTICAL,
            true, // include legend
            true, // tooltips
            false // urls
        );
        NumberAxis rangeAxis=new LogarithmicAxis("Y");
        XYPlot plot=(XYPlot)chart.getPlot();
        plot.setRangeAxis(rangeAxis);

        //chart.getXYPlot().setRangeAxis(
        return chart;
    }

Perfect. Sigh. So easy yet so very far away from what I was trying.

I blame my coworkers - they never stop talking

Thanks very much!
