I used the Aspose interface to convert static Excel to HTML, and found that the effect of histogram in html is different from that in Excel histogram excel.png (57.9 KB) histogram html.png (32.9 KB)
java code:
Workbook workbook = new Workbook(“dir//3333.xlsx”);
workbook.save(“dir//3333.html”, SaveFormat.HTML);
After an initial test, I am able to reproduce the issue as you mentioned by converting your template file to HTML. I found histogram chart is not rendered properly in XLSX to HTML conversion. I have logged a ticket with an id “CELLSJAVA-43795” for your issue. We will look into it soon.
