No add-ins necessary, just use Excel. You can put your data in decimal hours
if you want, or enter it as hh:mm format. Don't include text labels in the
same cell, or Excel will treat the times as categorical labels. Make an XY
chart, not a line chart, with the times as the X values and your other
variable as the values.

Hi
I have a temperature graph that I need to chart over time. From 0 to
168hrs
but the Log chart in Custom Types gives me even spaces between the times
which is not what I want .25mins to 168 hrs? If I was to plot the graph
in
minutes it would be too vast - huge!
Is there any add-ins available to do this type of graph.

Thanks
