RE: [ncl-talk] map tick mark problem

You are correct in your interpretation of the "grid point number tick marks."

What I am doing is plotting maps of a variable from several different data sets or times and then making them panels on a single figure. For each of the individual maps, I am using gsn_csm_vector_scalar_map or gsn_csm_contour_map.

I have attached an example image and an example script. The relevant function starts at line 786 and ends at line 956. It plots the seasonal average of 700 hPa height and wind from three WRF runs and MERRA and NARR.

Thanks,
Nicole

Hi Nicole,

There's not enough information here. It would help if you could include an image and/or some code.

By "grid point number tick marks" it sounds like you mean tick marks that are labeled with index values, rather than actual coordinate values?

If you are seeing both these *and* map tick marks, then this leads me to believe that two plots are being drawn on top of each other, and you are seeing the tick marks from both of them.

Usually, if you are drawing two plots on top of each other, you want to use the "overlay" procedure. This procedure will take care of removing all the tick marks from the plot that is being drawn on top of the other plot.

Again, it would help to see some code and or an image.

Thanks,

--Mary
