Inconsistency in bar colors and legends after update

[divyanshud13]

Hi,
I tried to update config of my chart which was
data.groups, data.columns, axis.x.categories which changes with every request. As soon as I update the chart I faced 2 issues

1. Inconsistency in colors between bar and legends.
2. Bar height is less although having correct data.

Images before and after refreshing are provided in the link.

The above issue is also posted on stack overflow where you can have a look on code snippet
