I am writing a macro that changes the series of charts. I have had big
trouble in getting this to work, forcing me to manually delete and then
repaste series on a daily basis to get it to work. Does anyone have any tips
regarding what to do to get the series to change I would be very happy. I
have some questions in this field:
1) My code now simply sets new values like this:

ActiveChart.SeriesCollection(priceArray(k)).Values =
Sheets(priceArray(0)).Range(rng(k).Offset(i, 0).Address & ":" &
rng(k).Offset(j, 0).Address)

Is this recommended or is there ant other way you should do it e.g.
SetSourceData or something?

2) I have tried using substitute/replace? Is that better? Basically if
anyone has any tips in this area I would be very grateful! Thank you all very
much!
