Outfit of all charts has changed suddenly by itself

Do you know why the outfit of our all charts and layouts have changed suddenly by itself? We haven’t done any changes by ourself. For example all the fonts have changed and names in legends have stricken through. We have about 160 different charts and it would be hard to modify them back manually.

So is there something we can do to restore original outfits?

The problem is caused by an update to the Highcharts library we use to generate charts. The latest version of which included some visual changes, and we picked these up automatically.

We will revert these changes back to how it was before!
