I opened your provided Excel file into MS Excel 2007 and 2016. Both shows those crowded x-axis labels, similar to output image/HTML. Please find attached the screenshot for your reference. sc_shot1.png (72.7 KB)
It seems Excel and Aspose are performing different logic to figure which units(months, weeks, days,…) should be used for X axis when the setting is for auto.
And it seems to work better if you explicitly set what you want in Excel.
