cfchart issues from 7 to 8

For the past couple of months I have been working in a sandbox environment running cf7. I am working on a dashboard component for monitoring several file counts on various servers within the network.

I am displaying the data as a stacked chart. The data is called through a few invoke/component scripts.

The structure for the charts I am using is as follows...

Now, on CF7 this displays as two columns, with two bars stacked on top of each other with the correct values replacing the var#'s.

I moved the script to a new CF8 box, and the graph doesn't function as it did previously. No code changes have been made...on the CF8 box the two columns are still there, but there would be 4 bars stacked on each other, and both columns would have the same values.

Example:
var1 = 1
var2 = 2
var3 = 3
var4 = 4

CF7 Graph Output:
Column1 stacked with var1(1) and var2(2) with a total column value of 3.
Column2 stacked with var3(3) and var4(4) with a total column value of 7.

CF8 Graph Output:
Column1 stacked with var1(1), var2(2), var3(3), var(4) with a column value of 10.
Column1 stacked with var1(1), var2(2), var3(3), var(4) with a column value of 10.

Any ideas? The examples are pretty basic, but due to privacy policies I can't share the exact code...nothing really sensitive but that's just how it is.

Thanks in advance.
