linear Gauge not work on IE11

[ybenameur]

Hi
Version 2.1.1
i tested the 2 examples shipped with the download .i tried them on Firefox all is ok but on IE they dont work at all ( black screen with 2 buttons : animate & stop animation).
1.linear-component.html
2.linear-min-non-zero.html
in edge they work as well.
in the html code i added the meta tag
meta http-equiv="X-UA-Compatible" content="IE=edge" (with brackets)
but not sucessfull.
Another question : how can make lineargradient or a clipped image as gauge background ?
thank you.
