Lingroup,

you have the code write to the same cell for every chart when you apply it to charts (for Radarscreen aiRow would take care of using a different cell).
Therefore you could create an input for the cell number and have each chart write to a different cell (take a look at how it's done in your code with using aiRow; you can even add some more code to check if the study is running on a chart or in Radarscreen and use the row input only when the study is applied to a chart).
