Hi,

I am working with some flow data which I have in hourly time steps. I want to split this into 15 minute time steps with some simple linear interpolation between the hourly values. I know I could work down the data interpolating between each hour, but is there a faster way? The rate of increase/decrease in flow changes each hour. Is there a better way to set out my data to do this? The data set is quite large and at the moment is set up like this:

Time Flow
0900 3.4
0915
0930
0945
1000 5.2
1015
1030
1045
1100 6.0

Thanks for any help
