When rendering charts to images, lines appear

This problem occurs for charts Adj.EBITDA_YTD and Adj.EBITDA_MTD in worksheet Appendix D - Adjusted EBITDA AD, Excel file input.xlsx

Charts are also rendered with lines when the Excel file is opened via Excel Editor Online for Free

Repro code:

Workbook workbook = new Workbook("input.xlsx");
Worksheet worksheet = workbook.getWorksheets().get("Appendix D - Adjusted EBITDA AD");
ChartCollection charts = worksheet.getCharts();
Chart chart = charts.get("Adj.EBITDA_YTD");

ImageOrPrintOptions options = new ImageOrPrintOptions();
options.setVerticalResolution(300);
options.setHorizontalResolution(300);
options.setImageType(ImageType.PNG);

chart.toImage("chart.png", options);

input.zip (3.8 MB)
chart.png (106.9 KB)

attaching input.zip (contains input.xlsx) and chart.png file from repro code.

Zoom in chart.png if lines are not visible at first glance.

We are using Aspose Repository Browser /java/repo/com/aspose/aspose-cells/23.4/
Reproduced the same problem with version 23.6
