Hi,
It looks to me like you want to display four channels on a quadrant separated plot. The reason that there is only one output on the manually created chart is because the input array has been resized to be a 1x1 array. The indexed arrays that you create from the resized array end up just being copies of the resized array.
I recommend trying to index the array without resizing and plotting the indexed values. I'm not sure if the manually created chart will actually display four outputs, so I recommend plotting each of the channels on their own and then trying to combine them onto one chart.
Hope this helps!
