<p>Hi all,<br>
<br>
I am using “gsn_csm_xy3” function to have an XY plot with three different Y axes (figure is attached). A horizontal reference line is added by “gsnYRefLine” resource for the right Y axis with these lines:<br>
<br>
resL@gsnYRefLine = 0<br>
resL@gsnYRefLineColor = "forestgreen"<br>
resL@gsnYRefLineThicknessF = 1.0<br>
resL@gsnYRefLineDashPattern = 0<br>
<br>
When I simply try to add another reference line for the rightmost Y axis with following lines, I am receiving “warning:TransformPostDraw: tfPolyDrawList element 0 is invalid”:<br>
<br>
resM@gsnYRefLine = 0<br>
resM@gsnYRefLineColor = "red"<br>
resM@gsnYRefLineThicknessF = 1.0<br>
resM@gsnYRefLineDashPattern = 0<br>
<br>
What I have understood from NCL mailing archive, this warning message is related with multiple calling of “gsn_add_xxxx” functions. However, I don’t have any idea why NCL does not draw the reference line for the rightmost Y axis for this case. I could probably draw it by using “gsn_polyline” but I would be pleased if anyone suggests a way to do it with “gsnYRefLine”.<br>
<br>
NCL: 6.2.0<br>
<br>
Thanks in advance,<br>
<br>
Deniz<br>
