Evening,
I'm trying to show on my axis the time of the day in 20 minute intervals. At the moment I have a time table which has the time by the second as well as a second column which I've extracted the time by the start of the hour.
I was wondering if anyone new of a way to format or configure as to show for example:
7.00am-7.20am
7.20am-7.40am
7.40am-8.00am.
My best thought was to use a conditional column in order to calculate this; but considering my time column in terms of granuality the highest possible would be "7:21am"; I would I have to do If 'time' contains "7.21am" = 7.40am. And even then, I'm not sure I would be able to filter and sort it appropriatly.
Thoughts and feelings?
