      <div dir="ltr">Hi Tao,
        <div>1 - Dennis is correct. The Y-axis is hard coded for
          normalized standard deviations. You can pass in whatever
          values you want to the taylor_diagram function, but the Y-axis
          will stay the same. You can alter this in the function code,
          but, you will also have to alter the coding for the drawing of
          the concentric rings, and that might be difficult. </div>
        <div>2 - You cannot precisely positionally set the ring labels
          using the method I detailed. If you want to exactly specify
          where the labels appear, you would abandon the approach I
          recommended (with modifying the respl resource list) and
          instead add 4 new gsn_add_text calls (one for each green
          ring). As to why the 0.25 label does not appear: I am guessing
          that your value of gsLineDashSegLenF is too large. If you set
          that resource to a smaller value I would gather that the 0.25
          label will appear, but also additional labels will appear on
          the other rings. You can alter the setting of this resource
          for each iteration of the do loop (similar to how you are
          altering the setting of gsLineLabelString). </div>

              <div dir="ltr">Hi Tao,
                <div>I believe you corresponded with someone offline
                  about this. I have some experience modifying the
                  taylor_diagram function, but I have not done what you
                  are looking for so I can only offer recommendations.
                  You will likely need to make several attempts getting
                  all the resources set the way you want; hopefully your
                  test script runs quickly!</div>
                <div><br>
                </div>
                <div>To answer your 3 questions:</div>
                <div>1 - Yes.</div>
                <div>2 - I believe this is possible. Steps required:</div>
                <div>   - Copy the <a href="https://www.ncl.ucar.edu/Applications/Scripts/taylor_diagram.ncl" target="_blank" moz-do-not-send="true">taylor_diagram.ncl</a> code,
                  and saving it as (say) taylor_diagram_2.ncl. </div>
                <div>   - Alter the function name at the top to
                  taylor_diagram_2 (at line one of
                  taylor_diagram_2.ncl). </div>
                <div>   - In your new function, go to the section
                  entitled "Part 3". You will see a resource list that
                  is initiated 5 lines beneath "Part 3" named respl. I
                  would try adding the following resource settings <b>beneath</b>
                  the current respl resource settings:</div>
                <div>     respl@gsLineDashSegLenF = 0.30.   ; Controls
                  spacing between line labels; this setting will require
                  some trial and error.</div>
                <div>     respl@gsLineLabelFontColor = respl@gsLineColor</div>
                <div>     respl@gsLineLabelFontHeightF = 0.0125.   ;
                  this font height setting might need adjustment</div>
                <div><br>
                </div>
                <div>  - Then, within the "do n-1,ncon" do loop, you
                  will need to tell NCL how to label the lines, so try
                  this:</div>
                <div>      do n=1,ncon</div>
                           rr  = n*dx    
                <div>           res@gsLineLabelString = rr.   ; add this
                  line</div>
                <div><br>
                </div>
                <div>That should do it. As I stated in the comments
                  above, you will likely need to adjust the setting for
                  gsLineDashSegLenF and gsLineLabelFontHeightF.</div>
                <div><br>
                </div>
                <div>3 - Yes. Search within the function for the
                  resource "gsLineColor". You can adjust these as
                  needed.</div>
                <div><br>
                </div>
                <div>Hope that helps!</div>
