Troubles setting parameters

[JulieMay]

Hey,

I made a 30 by 30 graph and am having troubles with usability of this graph in print. The issues are due to lack of control over tick marks, gridlines, and the font exporting much smaller than I set it to be.

1. I don't want tick marks for every 1, only every 10. I don't know how to change this even after reading the help file I saw no control over tick frequency that goes below higher than 1.
2. 30 by 30 font size 10 isn't really font size 10 either. The font is scaling down like mad and barely understandable.
3. I would like to see only a certain range of -30 x to +20 x and 30y to -10 y. I cannot figure out how to do that at all. This is also contributing to the font size issue where everything is so tiny. When I export it lets me set a range, but the export includes the full range instead of the range I set.
4. I would like grid lines to only show every 5. I see no way to control how often they show when less often than every 1 is desired.
