show minor unit and minor grid on log log chart
(OP)
I see on a previous thread that the major units on log log have to be powers of 10. If someone knows how to change this, let me know.
My question is, how do I show minor gridlines and labels on log log charts. For example, the chart runs from 1 to 100 on x axis, and 1 to 100 on y axis. I want to show gridlines between 1 and 2, and also between 10 and 20, and between 100 and 200. Is this possible without interpolating and using drawing tools to do it?

If you hadn't thought about this, you could just add some additional "series" to your graph so that the additional gridlines you want are actually plotted as part of your graph.
Of course this requires some extra effort but not a lot. For example, to show a minor gridline at Y value of 2, plot the following:
X Y
0 2
100 2
This should give you a horizontal line at Y=2. Then just repeat for your other gridlines. You will want to minimize the formatting for those series so make them all the same color and display with markers, etc. You could display the data labels if you want to show the value of the gridline or just add a text box with appropriate value in the appropriate place.

This is very annoying especially when dealing with e.g. fatigu e data. You often see published data where there is labels for
1,10 and 100 MPa but the actual data points lie between 100 and 150... this does´t look good at all.
Has anyone seen a program that can do decent plots ?

Have never used Origin, so don't have any basis for comparison
