Numbers duration chart

by chewsome / April 11, 2010 8:18 AM PDT

I have a list of training times (duration mm:ss) in a table: 25:34, 24:55, 26:12 etc. When I select all the times and create a chart no data appears on the chart.

The Y axis (value) should be in time ie 00:00 - 30:00 but is 0.00 - 4.00

Any help greatly appreciated.

Duration not available??????

I have been completely stuck with this. In the chart inspector the 'format' drop down menu has 'number' 'currency' 'percentage' etc. and I can create charts with these, but not 'duration'. Why not? I can understand why 'date & time' is unavailable but not duration???

Basically I am training for a running race and want to see my progress in a line chart as my times get quicker each week.

Could it be that those numbers,
by mrmacfixit Forum moderator / April 12, 2010 10:01 AM PDT

24:50, 25:30, etc (not your actual number I know) are not being treated as numbers.

If you add them together, they do not come out correctly, based on time.

Maybe numbers does not recognize them for what they are, minutes and seconds, which throws everything off.

Try this:
Instead of minutes and seconds, use the decimal equivalent. 24:30 becomes 24.5 and so on.

A list of numbers with decimals produces a graph quite easily.

would that help?

Thanks for that but it should recognize it.

If you add 24:50 and 25:30 in Excel it works, ie = 50:20. It's duration not time of day. Charts like this work in Excel easil enough too.

I know I could change all the times into decimals and it would work but that defeats the whole purpose.

You can't do this...

sorry this is a bit late...I ran into this problem late last year...

Numbers will not graph time durations. You have to convert the times to total minutes or hours first...and it will graph those.

ie. 1:20 convert to minutes is 80 mins
2:30 convert to hours is 2.5 hours...
