Different views for graph plotting

Hi, I have a unity using vectrosity and I will plot a graph. However, I have a total of 6 graphs to be displayed and I want to split the graph into 1 or 2 views only. For example, it is displaying a graph for 1 data and upon clicking keyboard button "E" I want to change the graph plotting to display "E"(e.g. temperature) data.

1 possible way I can think of might be is to use use VectorLine.destroy() to destroy the lines but I somehow couldn't use it in unity.

Another possible way is to set the line to be inactive using vectorline.active = false, however, is there a way to replot the graph when the line turned active again? Any help?

Can anyone advise me how can I achieve this? Thank you!
