The goal here is to have it filter on all columns except for the first 
column the X-axis column (in this case date)

Perhaps this will help. Image you are in heading the analytics department 
for a major car company. You have 4 major stores that depend on you for 
adjusted sales data. (Only corporate knows how many cars are really sold 
because consumers can return cars at any store).

Store 1 sales all models
Store 2 Sales only Models A,B,C
Store 3 Sales Models B,D,E,F
Store 4 Sales Models A,C,E

So the goal here is to create a visualization that will display dynamic 
amounts of information since not all stores are interested the same data. 
Some stores are interested in only certain models and couldn't care less 
about the remaining models. 

To create a static chart you must format the data with the sales by models 
in additional columns (See sheet Standard Format).Column A: Month, Column 
B: Model A Sales, Column C: Model B Sales, Column D: Model C Sales etc.. 
This accomplishes exactly what we would need if we were presenting to the 
CEO however, this chart is for store managers who are interested in 
breaking apart the data further. 

In excel, to accomplish the goal I would change the format of the data (See 
sheet Modified Format). Column A: Month, Column B: Model, Column C: Sales. 
I could then apply a filter to column B and dynamically control the chart 
based on model. In my initial post I tried to replicate this but was unable 
to as google script - Charts didn't support this data format (Modified 
Format).

The other possible solution is for a column data filter where I could 
dynamically select which columns of data to include (Standard Format).

I hope that I have illustrated a simple version of what I'm trying to 
accomplish. We have discussed earlier about created a simple dialog box 
that could work to statically filter out certain columns of data before the 
chart was rendered but that I feel defeats the power of google dashboards.
