Only the last background color shows up in the line chart

[raul1991]

Expected Behavior

I expected all the colors but seems as if the last color gets shown and others are hidden behind it.

Current Behavior

Only the last dataset's background color is shown

The black markers above point to the different colors for the datasets yet only the last one(shown at the top) is being shown.

Possible Solution

Steps to Reproduce (for bugs)

My color object looks like this

'graphConfiguration': {
			'colors': {
				'tpgs': ["#CA9BC1", "#EE7A75", "#99A9BF", "#66A19F", "#CA9BC1", "#EE7A75"]
			}
		}

I fill the background color on the fly using js like this
lineChartData['datasets'][i].backgroundColor = graphConfiguration.colors.tpgs[i];
