Origin Version (Select Help-->About Origin): 7.5 SR6
Operating System:Windows XP Pro

I have a set of data points that are plotted on a Log-Log plot. That works fine. What I want to do is increase a small portion of the plotted results by setting the scale to the range i am interested in. The range I "blow up" is for 1 decade (from 600 to 9000 along x axis).

The problem i have is that there is only 1 major label shown at 1000 and I can't seem to find any option to be able to show more. Any help with this? I've tried to increase the number of major ticks but that can't be controlled.

**Update**

If i change the range in my data to 1000-9000 all the major labels now show up at 1000 increments...is this a bug? Seems like i can't control the increment labels in log-log plots.

Hi. Would you please tell me what the range of the X values is? And the Increment for X axis, which you see in the Axis Properties dialog?

Deanna,

From the x - Properties Dialog: 600 - 9000, increment = 1

Some more info:

The range was from 600 < x < 9000. Only way anything shows up on the x axis plot is if the increment is 1 otherwise nothing shows up (xlabels disappear). If I increase the range to start at 1000 the labels show up at 1000 increments but that isn't controllable. Basically all or nothing above x = 1000.

Thanks for the suggestion but that would have me make a new axis.

I guess I could, on another sheet write my own x-label values and use that as the major tick labels. Just that the linear x-y plot works so nicely, why wouldn't it be the same for a log-log plot?

Hi,

You don't need to make new axis, and it works for log scale too. Like this:
