[ncl-talk] how can i close one tick mark label when it display two?

[半个丑角]

Dear NCL development or NCL users,
     Thank you for reading my letter in your busy day.
      I have drawn six plot together without using panel, like the example NCL shown in this link: https://www.ncl.ucar.edu/Applications/Scripts/panel_23.ncl
      In this case, I need to close all tick mark labels and open them conditionally, and that was what I have done. But in my graphic, I set a mpcenterlat and a mpcenter lon, so the fictitiour graticule is not as regular as a rectangle before, the latitude and longitude lines become an arc. Then each plot which drawn a tick mark label, display more than one tm label, it has two. The one was under control (I can set labelfont attribution or some others), and in the correct position, linking my latitude or longitude lines drawing in the plot. Another one was out of control and with a wrong position.
       I have tried to change the pmtickmarkdisplaymode, it would close the right labels and set the wrong one. Also, I have searched in the NCL website to find a resources to draw a correct one in the situation that change pmtickmarkdisplaymode into "nocreate" or "never", but I haven't found out.
       I don't know how to fix it now, if you all have some solution, please write to me.
       Thanks again!
  
 sincerely,
 Lucky
