chart.toImage generated image - axis tick labels are overlapped- where as in actual chart- they are properly aligned

Hi,
Please find the sample below, with which you can reproduce the issue -
chart.toImage generated image - issues.
1. axis tick labels are overlapped, where as in actual chart, they are properly aligned.
2. when we hide axis tick labels, they are visible in image.(Uncomment red blue line for this)

chart.getCategoryAxis().setTickLabelPosition(TickLabelPositionType.NONE);

Please find the sample output. Image still differs from actual chart, especially when we have neg values.
The issue is in chart, tick lables and inside chart area, where as in image, its out side.
