Issues with Combo Chart (fully accumulated stacked bar chart with line)

[#1]

Hello

I have two issues with Combo Chart:

1. Full Accumulation in Stacked Bar

It works fine when I have just 1 dimension. But when I add 2nd dimension, display gets distorted (last 5 graphs).

2. Line Chart

When I enable Timeline, stacked bar chart gets distorted (no more showing stacked bars)

Please help me out. Thanks in advance!
