I had cgHistoplot working fine with multiplot for a while. At some point it stopped working...
I have the updated versions of multiplot and cgHistoplot.
What is happening is that all the histograms are drawn on the same reference frame and only one reference frame is represented. Though multiplot works perfectly well when I use just plot. I also tried to overplot the histogram but it does not work.
I am running something like that:
SET_PLOT, 'x'
erase
multiplot,[1,3]
cgHistoplot, map1, XRANGE=xr, /FREQUENCY, YTICKFORMAT='(F4.2)', /OUTLINE
multiplot
cgHistoplot, map2, XRANGE=xr, /FREQUENCY, YTICKFORMAT='(F4.2)', YTITLE='', /OUTLINE
multiplot
cgHistoplot, map3, XRANGE=xr, /FREQUENCY, YTICKFORMAT='(F4.2)', XTICKFORMAT='(F5.1)', YTITLE='', /OUTLINE
multiplot,[1,1],/init,/verbose
Any suggestion?
