Large data with specified colors for column chart displays different color

[padmaruban]

Hi @amcharts ,
Im using multipanel chart. I have large data set with colors for the column chart in it.
It is displaying column chart properly with the specified colors, when I use it with lesser data.

It is displaying column chart properly with the specified colors, when I zoom in to the minimal duration as shown below

When I zoom out to the normal, It displays the column chart in single unspecified color (#FF6600) as follows

we need to make it displaying with the colors as I specified in the dataset.

Please refer the codepen here https://codepen.io/padmaruban/pen/bPdzqy

Any help is appreciated, Thanks in advance.
