chartjs uncaught referenceerror 3a utils is not defined

1/* The chartjs team decided to use an random/obscure utils file in
2all of there code samples.You will need to download the utils file
3and maybe rework it to get the samples working, but the chartjs team
4basically says don't use their utils bc it will break, so you may be
5better of just looking at what it does and pulling in the needed 
6functions or replacing any Utils references with your code*/
