FormatTrait.php(193): Notice - A non well formed numeric value encountered - Matomo 3.10.0

On the dashboard an orange alert box appers with following error message:
“WARNING: httpdocs/st/vendor/davaxi/sparkline/src/Sparkline/FormatTrait.php(193): Notice - A non well formed numeric value encountered - Matomo 3.10.0 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already)”

It seems its not reported here in the forum for the FormatTrait.php file, so i created this post as mentioned in the error message :slight_smile:
