logarithmic scale

[lone]

I have a problem which I can't figure out how to solve: I have som data in the range 10 000 to 40 000 and I want to present then in a (x,y)-diagram (I have years from 1980 till 1990 on the x-axis) with logarithmic scale (10-log). But when I choose that, the y-axis will automatically be from 10 000 to 100 000. I would like to have the y-axis from 10 000 to 40 000 and with gridlines between with the numbers 15 000, 20 000, 25 000, 30 000 and 35 000 (which then of course have different length between them). Is this possible? Can I program it in Visual Basic perhaps?
I really would appreciate your help.
Yours Sincerely
Lone Christensen

Why are you intent on using a logarithmic scale on the y-axis? What's the nature of these values?

Hi,
You need to format the axis.
Place your cusor over the y axis. Left click
This should open the format axis dialog box.
select the scale tab.
Uncheck the auto box against maximum and minimum and enter the values you want.
You can also select the values for the intervening ticks.

Good Luck

It seems that minimum and maximum in logarithmic scale are set automatically to n^10 intervals, and there is no way to choose values inbetween.
