Semi Circle Doughnut chart not displaying when running through IIS

So I designed a dashboard that implements a semi cirecle doughnut chart. This was all working, As in the dashboard worked when I tested it locally on my machine in IE and Firefox etc. But as soon as I published the dashboard to IIS like I have done for the other 6 dashboards Im running the semi-circle chart no longer displayed. Run the same code, but just through not through IIS and it works fine. Anyone had this issue? I have logged this on github.

Sorry it was me being an idiot…spotted the issue so not an issue just me…

I answer my own questions so many times. Most of the time, right after I post a question!
