@Sergei Baklan I think It is pretty clear " Create multiple Graphs" multiple means more than one. You just explained how to create a chart which is evidently known already. If he needs to create multiple he must know how to create one.
Sorry for my level of sarcasm, included in this apology
No, you cant have multiple different graphs from the same pivot. If you create more than one, changing one will change all others. The alternative is to copy and paste values and create many graphs from the value table, or if you want it dynamic, create a parallel table that calls out the values from the pivot table, so every time the pivot changes your parallel table will also change. You do can create multiple graphs from a table (not pivot) and display different values in every graph
