Series became hard-coded in graph and I don't know why...

[antaeusguy]

I've created a graph which the series link to a range with values.

If the values changes, the graph series will also change.

However, I forgot what I did I do the graph, and the series became hard coded with values.

Linked to ranges:
=SERIES("Previous year",Dashboard!$C$99:$C$110,Dashboard!$D$99:$D$110,1)

Hard-coded:
=SERIES("Previous year",Dashboard!$C$99:$C$110,{13170.0559978919,11302.4710116538,9805,29005,8851,10429,10207,10777,12370,12265,12933,14758},1)

Does anyone know how did the graph series changed from linked ranges to hard-coded values? So that I will be aware of my actions.

One way to do that, which can be useful if you want to email a chart without the underlying data, is something like:
Select the series line in the chart.
F2
F9
Enter
