Number of events by day and hour

Hi all,

I would like to set up a graph with number of events by hour and by day.
I don't know how set up data on the spredsheet to do it easily.

Formula and or VBA welcome.
If you have some ideas to present such data, it's welcome too.
I also wanted to establish a chronological curve with dates and times that would allow me to see if the same pattern is replicated every day, but don't know to do it ...

Do tell me if the above is a good direction...
only one line of macro in the code to reset the chart.

BTW, the line could also be
Target.Worksheet.ChartObjects("PeriodChart").Chart.SetSourceData Source:=Range("Period", "Values")
An interesting thing I learned today is:
You can have a dynamic range over formulas (not just values) like this
=OFFSET(Sheet1!\$F\$1,,,COUNTIFS(Sheet1!\$F:\$F,"<>",Sheet1!\$F:\$F,">0"),1)
provided F contains numbers.
@Gbanik,

You don't need a macro to make a chart dynamic. You can plug the dynamic range names straight into the series formula.

=SERIES(Sheet1!\$G\$1,TimeChart.xlsm!Period,TimeChart.xlsm!Values,1)

Also, an alternative for defining the dynamic range is

=Sheet1!\$F\$2:INDEX(Sheet1!\$F:\$F,COUNT(Sheet1!\$F:\$F)+1)

cheers, teylyn
teylyn thx again :)  .... new learning everyday :)
(but alas... and forgetting a few good ones too!)
