Question

I have dynamic data shown in Excel. The data itself is pulled using COM from external application, and it is basically number changing over time (for example, outside temperature which is received from weather website).

Is there some convenient way to store MIN/MAX() of value observed during some period without use of VBA and macroses? Using simple formula in max_cell like =IF(data_cell>max_cell, data_cell, max_cell) gives circular reference.

Answer 1

If you turn Iteration on then the circular reference will work ok on a continuous basis

And rather than an IF you can just use in A1 (where A1 is max_cell, A2 data_cell)

=MAX(A1,A2)

Enabling Iteration

• In Excel 2003, From the Tools menu, select Options. 2. In the Calculation tab, select the Iteration checkbox and click OK.
• Iteration xl2007
• Iteration xl2010
