Image generated with small chart size is not rendered properly

Hi,

Please run the following sample and see that

1) When chart size is small, chart in the image is not rendered properly.
2) Increase chart size to bigger values say - Chart chart = chartSheet.getCharts().addChart(ChartType.COLUMN_CLUSTERED, 0, 0, 1, 1, 624, 383);
Now see that category axis tick labels are not present in the image. instead, 1,2,3 etc... are shown

Thanks
Muhammed
