Thanks Carl, sorted.
Funnily enough, looking back at my old code thats what I did before! plus
for the sizing:
oText->SetProperty, CHAR_DIMENSIONS = [3,3]

In short, use the TICKTEXT property.
For example,
oAxis = OBJ_NEW('IDLgrAxis', /USE_TEXT_COLOR)
xobjview, oAxis ; default axis - all black
oAxis->GetProperty, TICKTEXT=oText ; Note that a single text object is
returned, containing a string for each tick.
oText->SetProperty, COLOR=[255,0,0]
xobjview, oAxis ; ticktext is now red
oFont = OBJ_NEW('IDLgrFont', SIZE=20)
oText->SetProperty, FONT=oFont
xobjview, oAxis ; tick text is now bigger
