TypeError when rendering a Pie chart

[frederikcreemers]

I'm getting the following error:

Chart.js:30 Uncaught TypeError: Cannot read property 'offsetWidth' of undefined
    at computeDimension (Chart.js:30)
    at new Chart (Chart.js:40)
    at ChartComponent.renderChart (index.js:227)
    at ChartComponent.componentDidMount (index.js:77)
    at ReactCompositeComponent.js:265
    at measureLifeCyclePerf (ReactCompositeComponent.js:75)
    at ReactCompositeComponent.js:264
    at CallbackQueue.notifyAll (CallbackQueue.js:76)
    at ReactReconcileTransaction.close (ReactReconcileTransaction.js:80)
    at ReactReconcileTransaction.closeAll (Transaction.js:206)

Looking through the functions referenced in the stack trace, it looks like the canvas element couldn't be found in the dom.

I'm using the chart exactly as in the examples, and I have no idea what might be different between my app and the examples app that might be causing this difference. Could the way webpack bundles things cause issues?

Turns out I had an older version of chartjs installed. Upgraded to the latest version, and now it works.
