jzy3d - improper grid lines on Windows 7 when drawing a shape to a canvas of a chart

HI,

I am using jzy3d library for drawubg 2d and 3d models.

private Shape getSurface(double[][] plotValues, int steps) {
                // Create the object to represent the function over the given range.

                ArrayList<Variable> selectedVars = surrogateModel
                                .getSelectedVariables();
                Variable selectedVar1 = selectedVars.get(0);
                Variable selectedVar2 = selectedVars.get(1);
                Range range1 = new Range(selectedVar1.getMinRange(),
                                selectedVar1.getMaxRange());
                Range range2 = new Range(selectedVar2.getMinRange(),
                                selectedVar2.getMaxRange());

                // final Shape surface
                final Shape surface = (Shape) ExtendedBuilder.buildOrthonormal(
                                new ExtendedOrthonormalGrid(range1, steps, range2, steps),
                                plotValues);
                surface.setColorMapper(new ColorMapper(new ColorMapRainbow(), surface
                                .getBounds().getZmin(), surface.getBounds().getZmax(),
                                new Color(1, 1, 1, 1f)));

                surface.setWireframeDisplayed(true); // sets/unsets the black

                // gridlines on the plot
                if (surface.getWireframeDisplayed())
                        surface.setWireframeColor(Color.BLACK);

                if (selectedVars != null) {
                        String xLabel = selectedVar1.getName();
                        String yLabel = selectedVar2.getName();
                        String zLabel = surrogateModel.getSelectedResponse().getName();
                        setAxeLabels(chart1, xLabel, yLabel, zLabel);
                        setAxeLabels(chart2, xLabel, yLabel, zLabel);
                }

                IAxeLayout layout = chart1.getView().getAxe().getLayout();
                colorbar = new Colorbar(surface, layout);
                surface.setLegend(colorbar);
                return surface;
        }


                predShape = getSurface(plotValues, steps);
                predShape.setLegendDisplayed(false);
                chart1.getScene().getGraph().add(predShape, false);

         component1 = (Component) chart1.getCanvas();
                component1.repaint();


I am adding this surface to my canvas.

The grid lines appear fine on Windows XP.

But when i switch my OS to Windows 7, the grid lines are no longer straight... the grid is not displayed properly on Windows 7.

Can anyone help me with this?

Hi

Are you sure that the difference comes from the OS? Please indicate which hardware you use on both machines.

Hi ,

Yes it can be a hardware issue.
I have windows XP on Desktop PC and Windows 7 on a laptop.
I would check the graphics controllers and let u know the difference.
Also what all information to you need when you say hardware?

Windows XP

Windows 7

The driver version number would be useful too.
