Excel chart is not rendered properly when converting it to PNG format

Hello,

I am using Aspose.Cells v19.4 to generate PNG of chart - “Chart 22” in the attached excel file. The PNG output is not the same as the original chart.
The y-axis labels are incorrect, the scale of x-axis labels is incorrect, y-axis title is incorrect and the legends are not appearing in a single line as in the original chart.

Following code is used to generate the output:

Workbook workbook = new Workbook(“test.xlsx”);
WorksheetCollection ws = workbook.getWorksheets();
String worksheetName = “IMR Regn”;
Chart chart = ws.get(worksheetName).getCharts().get(“Chart 22”);
ImageOrPrintOptions imgOptions = new ImageOrPrintOptions();
imgOptions.setImageType(ImageType.PNG);
chart.toImage(“aspose response 19.4.png”, imgOptions);

PFA below the source excel and PNG output:

Can you please look into this.

Thanks,

@Neha_Gautam,

Thanks for the template file and screenshot.

After an initial test, I am able to observe the issue as you mentioned by highlighting in the comparison screenshot. I used your template file and sample code and found the output image of chart has a few discrepancies. I confirmed the y-axis labels are incorrect, the scale of x-axis labels is incorrect, y-axis title is incorrect and the legends are not appearing in a single line as in the original chart. I have logged a ticket with an id “CELLSJAVA-42897” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.
