I tried it with no results. EXAMPLE:

values=['0','30','50','70']
values_pos=['50','55','76','256']
text_arr=objarr(n_elements(values))
for i=0, n_elements(values)-1 do begin
itext=OBJ_NEW('IDLgrText', values[i], FONT=self.font, $
RECOMPUTE_DIMENSIONS=2, /ENABLE_FORMATTING)
text_arr[i]=itext
endfor

;-- then the axis

axis=OBJ_NEW('IDLgrAxis', 1, TEXTPOS=1, TICKDIR=0, $
TICKTEXT=text_arr, /EXACT, MAJOR=N_ELEMENTS(values), MINOR=0,
TICKLEN=3)

axis->GetProperty, TICKTEXT=ticktext, YCOORD_CONV=ys
for i=0, n_elements(ticktext)-1 do begin
location=[ys[0], (values_pos[i]/256.)*ys[1]]
ticktext[i]->SetProperty, LOCATION=location
endfor

xobjview, axis
