Re: How to put marker above the Geophysical Line

Ziqiang,

I wanted to address your other comment about "gsn_add_text is not fit to add many text string to map".

You can pass an array of text strings and X/Y locations for each string to gsn_add_text in one call. Here's an example:

    . . .
    map = gsn_csm_contour_map(wks,data,res)
    . . .
    strings = (/"one","two","three"/)
    lat = (/10,20,30/)
    lon = (/90,90,90/)
     txres =True
    txres@txFontHeightF = 0.01
    txid = gsn_add_text(wks,map,strings,lon,lat,txres)

If you want each text string to be a different size, color, font, etc, then you will need to do this in a loop.
