Axis numbers appear in AWT render, but are absent in SVG file

[btipton-ds]

Thank you for this package. I've been searching a general, scientific plotting package since, oh, 1985. I've even written a few.

This is doing almost everything my team needs, but...

I get this in the java chart

But this in the svg file generated directly from that render

        final SVGGraphics2D svg2d = new SVGGraphics2D(bounds.width, bounds.height);
        chart.draw(svg2d, bounds);
        final String svgElement = svg2d.getSVGElement();        

        try (PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(path + "PV_diagram.svg")))) {
            out.print(svgElement );
        } catch (IOException ex) {
            Logger.getLogger(PlotterCarnot.class.getName()).log(Level.SEVERE, null, ex);
        }

I did a test of adding numbers to the axis labels, and those numbers appear.

Presto, the axis numbers have vanished. I've already tried the published solutions I could find. Most imply the axes are being drawn out of bounds, but the axis labels are closer to the bounds and still appear.

Thanks in advance.
