If the page using @media print will be printed in Firefox, ngx-charts's bars are losing their colours. In Google Chrome I can get a page that has been printed right.
Examples:
Firefox
The pictures are screenshots of print reviews in each browser, but if I save it as pdf, I still have the same issue.
I think it's something about ngx-charts. Has somebody any idea, why there is the issue and how could it be fixed?
