I may not understand exactly what you need, but I have a suggestion.
The trick is to reformat the data and use an XY graph. They allow for ultimate control of the displayed data because they just draw lines between the x-y points in their data array. I suspect the scaled data in your VI is in a cluster. Unbundle it, autoindex the array with a for loop, bundle in a "x value", pass the array of clusters to the xy graph.
