Hi,
Thanks for the template file and screen shots.
I have tested your scenario/ case using v8.5.0, it works fine. I used the following sample code and I do not find any additional space between the charts when viewing in IE browser type. I have also attached the output HTML file for your reference here.
e.g
Sample code:
Workbook workbook = new Workbook(“excel.xlsx”);
Worksheet worksheet = workbook.getWorksheets().get(0);
Cells cells = worksheet.getCells();
workbook.getWorksheets().get(“Data”).getCharts().get(0).setPlotVisibleCells(false);
HtmlSaveOptions saveOptions = new HtmlSaveOptions(SaveFormat.HTML);
saveOptions.getImageOptions().setImageFormat(ImageFormat.getPng());
saveOptions.getImageOptions().setTransparent(true);
saveOptions.setExportHiddenWorksheet(false);
saveOptions.setPresentationPreference(true);
saveOptions.getImageOptions().setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
saveOptions.getImageOptions().setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
saveOptions.setHiddenRowDisplayType(HtmlHiddenRowDisplayType.HIDDEN);
workbook.save(“f:\files\outExcel1.html”, saveOptions);
Let us know if you still have any issue.
Thank you.
