help with a chart....

[karthik_b]

I was trying to plot a line chart and in which it should take dates with an incremental of 2 hours on the X axis. I had three columns(X, Y, Z) in my list from which the chart should take the min of X date to max of Y date. Please help me how to derive the calculated column for this such that I can plot that as X-axis in my line chart.

I am attaching a copy of the report which was developed in EXCEL (I should use the min(OTS) and max(ETR))

Thanks in advance.
Please help me with a solution
