Chart.js does not work in Jenkins views due to conflict with (old) bundled prototype.js in Stapler

[Ullrich Hafner]

I’m trying to add some modern graphs in my plug-ins but only a few of them are shown correctly in Jenkins.
Did someone already integrate Chart.js successfully in a plug-in?

Is there a way to disable protoype on a page?

Why are we bundling such an old version? Jenkins: 1.6.0.2 (released in 2008), Latest 1.7.3 (released in 2015)

E.g. if I integrate the hello wold graph (http://www.chartjs.org/docs/latest/#creating-a-chart) I get a JS error:

For the record if someone else tries to use Chart.js:

Workaround:

replace war/scripts/prototype.js in JENKINS_HOME with the latest release 1.7.3
