Hi, You might try setting C_USE_LABEL_ORIENTATION=1 in your CONTOUR call. This will force it to use the text label's orientation. Let us know if this works. Cheers, Chris ITTVIS

Unfortunately, I had that set to 1 already. Setting to 0, the contour labels went every which-way in line with the contours. Setting to 0 keeps the labels horizontally aligned... just flipped upside down.

Here's the actual code: data=fltarr(12,37) (for reference) yvals=[1000,850,700,600,500,400,300,200,100] x=indgen(12)+1 p=1000-25*indgen(37) image=contour(data,x,p,layout=[2,1,1],n_levels=ncol,text_color=0,/ylog,yrange=[1000,100],xrange=[1,12],$ ytickv=yvals,xtickv=x,c_value=clevs,C_USE_LABEL_ORIENTATION=1,C_LABEL_SHOW=[0,0,1],/overplot) I have ommited the updir/baseline for now since I can't get them to change the orientation.

Hi Aaron, You're right. This looks like a bug to me. I'll go ahead and log it, and then fix it. For reference it's CR 60943. Thanks! -Chris ITTVIS
