<div dir="ltr">Hi Frank,<div>If you are asking for a second line of labels underneath a common labelbar, the answer is no a function does not exist, but you can draw a labelbar twice using <a href="https://www.ncl.ucar.edu/Document/Graphics/Interfaces/gsn_labelbar_ndc.shtml">gsn_labelbar_ndc</a>, moving the labels for the second labelbar downwards. Here is a snippet of code that I have used for this:</div><div> lbres = True ; labelbar only resources<br> lbres@vpWidthF = 0.6 ; labelbar width<br> lbres@vpHeightF = 0.06 ; labelbar height<br> lbres@lbFillColors = res@cnFillPalette ; labelbar colors<br> lbres@lbOrientation = "Horizontal" ; Default is vertical.<br> lbres@lbLabelAlignment = "InteriorEdges" ; Default is "BoxCenters".<br> lbres@lbMonoFillPattern = True ; Solid fill pattern<br> lbres@lbLabelFontHeightF = 0.016 ; font height. default is small<br> lbres@lbBoxLineColor = "gray70"<br> gsn_labelbar_ndc(wks,dimsizes(res@cnLevels)+1,res@cnLevels,0.205,0.19,lbres)<br><br> lbres@lbLabelOffsetF = .5<br> gsn_labelbar_ndc(wks,dimsizes(res@cnLevels)+1,RoundPastDecimal(sqrt(8./res@cnLevels),2),0.205,0.17585,lbres)<br></div><div> frame(wks)</div><div><br></div><div>Note that in the two gsn_labelbar_ndc calls, the NDC X value is the same (.205), but the NDC y-value is adjusted so that the labelbars themselves are exactly overlaid.</div><div>Adam</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Dec 2, 2019 at 2:01 AM Kreienkamp Frank via ncl-talk <<a href="mailto:ncl-talk@ucar.edu">ncl-talk@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
