Hello,

I'm trying to change the line width of the arrows in the map based, axesm specifically, function quiverm. The usual quiver funciton has a linewidth LINESPEC while I'm not sure if quiverm does.

Thanks,

Hello!

While there is no direct Name-Value argument to set "LineWidth" of the arrows of a "quiverm" plot, here's a workaround to modify the same:

load("wind","x","y","u","v")

lat = y(11:22,11:22,1);

lon = x(11:22,11:22,1);

dlat = v(11:22,11:22,1);

dlon = u(11:22,11:22,1);

figure

[latlim,lonlim] = geoquadline(lat,lon);

usamap(latlim,lonlim)

myquiverm=quiverm(lat,lon,dlat,dlon)

myquiverm =

2×1 Line array: Line (Quivers) Line (Quivers)

myquiverm(1).LineWidth=2 %for the lines

myquiverm =

2×1 Line array: Line (Quivers) Line (Quivers)

myquiverm(2).LineWidth=3 %for the arrowheads

myquiverm =

2×1 Line array: Line (Quivers) Line (Quivers)

You can store the output of the quiverm function to a variable. The variable is observed to be an array of two 'Line' objects. The first object controls the lines of the arrows, while the second one controls the arrowheads. So, modifying the LineWidth properties of these objects will alter the plot as needed. The data here has been taken from the example present in the "quiverm" documentation: https://www.mathworks.com/help/map/ref/quiverm.html#mw_bb73427a-2dad-496f-a3b7-573c1f36c527 .

Hope this helps!
