Hi All,

I am trying to generate several pivot tables from one data source table. I have successfully created my first pivot table (A date field, and a water storage facility level reading) and subsequently a graph from this. I have worked out that I need to group my dates as I am supplied a daily reading, but only need monthly average. All worked great.

Now i need to create more pivot tables and graphs. The next one I want is to create one grouped by years. But when I create this new pivot table and change the grouping of the date field to yearly, it also changes the grouping on my first pivot table, which is undoing my work. Does anyone know how to tell excel that these pivots are independant, and I dont want them changing in unison? See screen grab of my source data and where I am up to...

Thanks all.
