Write to three embedded charts on a worksheet using arrays

[cve60069]

I am trying to write to three embedded charts. My program reads data from a sheet, manipulates the data and writes three arrays of nodes to be plotted onto each chart. I created a stripped down version of my program and I attach the workbook. I have put a stop by each of the errors I am experiencing.

Any help to solve please.
