I am trying to plot a graph with the time on the y-axis and days on the
x-axis.. The chart is suppose to plot the trends of when a process is completed - this process includes 4 specific items. There are 4 daily tasks that are to be completed daily and I want to be able to plot this completion time in a chart so that the trends of when each item is usually completed can be noted. Another problem with this graph is that one item is completed the night before at 9PM but counts towards the next day's process and should actually be counted as the "start" of the items being processed. (i.e. I want the 9PM time from the previous day to appear at the bottom of the graph, and the later 3 process times to appear above the "start" time) Currently, the y-axis of my graph starts at 12:00AM and goes to 12:00AM and goes to 4:48AM again (So the Y-axis actually spans over 24 hours..) Can you please explain the logic behind how Excel chooses which "12:00AM" it uses to plot the points.. and how I can change this y-axis to display times from the previous nights and run into the day of the next day (i.e. 9PM from yesterday to 9PM current day) and whether I will then have to adjust my data so that it can be graphed at the appropriate 9PM (either yesterday or current day). Thanks for your help! |

Remember that Excel counts time in multiples of a 24-hour day, so 9pm is
0.875. 9pm a day later is 1.875. Recalculate from your data accordingly, and use those values as the limits on your Y axis.

Thanks David.
I changed the axis so that it runs from 9pm to 9pm a day later. However, I am now having problems with the data being plotted in the area that I want it to be plotted.. the 9PM data will appear on the graph but the data that is 2AM or 3AM the day later will not display on the graph since that is in the "negative" values that is not within the range of the 24 hours between 9PM and 9PM... How can I adjust my data so that it will be displayed? "David Biddulph" wrote: Remember that Excel counts time in multiples of a 24-hour day, so 9pm is 0.875. 9pm a day later is 1.875.

If you want to bring all your times within that range, why not
=MOD(A1-0.75,1)+0.75 (and format the result as time) ? -- David Biddulph "Mary" wrote in message ... Thanks David. I changed the axis so that it runs from 9pm to 9pm a day later.
