chart a location
 

I am trying to chart grid coordinates.
I have a 5 grids that I update, one for each day of the week.
I want a graph to pull data from all 5 grids and plot it the same way I'm
plotting it on the graph.

Example: On everyday I have 2 defects in grid coordinate E6. I want to see
5 data points on a chart that looks like a grid in E6.
