JFreechart lines and points?

I'm using JFreeChart and would like to have both a line on a graph and
several points. I started out using ChartFactory.createXYLineChart
which showed the lines well but the points only appeared in the legends
(perhaps they were too small to be visible on the graph). So I switched
to ChartFactory.createScatterPlot which shows the points wonderfully
but now my line is not continuous.
Is there a way to put both lines and well seen points on the same
graph? I was surprised that when adding points to a graph you cannot
select attribtues such as color, size, etc of the points.
Here is abriviated what I am doing...

....
               //=====>>>THIS IS A LINE<<=======
    XYSeries series = new XYSeries("EF");
        for (int i = 0; i < collection.numreturnstograph; i++)
        {

            series.add(collection.returns[i], collection.stddevs[i]);
        }

                            //===>>>THIS IS A POINT<<<===
        XYSeries seriesMVP = new XYSeries("MVP");
        seriesMVP.add(collection.MVPreturn,
Math.sqrt(collection.MVPvariance));

        // org.jfree.chart.plot.ColorPalette foo = new ColorPalette();

        XYSeriesCollection xyDataset = new XYSeriesCollection(seriesMVP);

                            //===>>>THIS IS A POINT<<<===
        if (collection.Custreturn != 0)
        {
            XYSeries custseries = new XYSeries("Current");
            custseries.add(collection.Custreturn, collection.Custvariance);
            xyDataset.addSeries(custseries);
        }

                            //===>>>THIS IS A POINT<<<===
        if ( collection.Rp != 0 )
        {
            XYSeries reqseries = new XYSeries("RequestReturn");
            reqseries.add(collection.requestedReturn,
collection.requestedStdDev);
            xyDataset.addSeries(reqseries);
        }

                                //add the actual EF line last so it is
behind the points when overlapping
        xyDataset.addSeries(series);

        // JFreeChart chart = ChartFactory.createXYLineChart(
        JFreeChart chart = ChartFactory.createScatterPlot(
                "Portfolio's Efficient Frontier", // Title
                "Monthly Return", // X-Axis label
                "Risk StdDev", // Y-Axis label
                xyDataset, // Dataset
                PlotOrientation.HORIZONTAL, true, // Show legend
                false, false);
....

Thanks!
