cannot read property 'map' of undefined

[sourcecodenepal]

I am getting this error. Is this because of jquery conflict? or am I doing something nasty in code?

I don't think you need to do window.myBar, try just:

myBar = new Chart(ctx1, { type: 'bar', data: barChartData1, options: options }

@sourcecodenepal can you post a JSFiddle for this?

Have you tried putting this inside
windows.onload = function () {

}?

I looked up all the uses of map inside of the source.

Does your data object have a labels array? It should also needs to have a dataset array. For a bar chart, this should only happen if the datasets array does not exist which is an error. I pushed a fixed in #2186 that better handles this case.
