Error in the simultaneous use of contourf and geolimits

5 views (last 30 days)
I have a problem with my code. I am trying to combine two kinds of maps. the first one is the contour map, and the ather one is the geomap with the geolimit command.
My code is above:
figure(5)
S=shaperead('C:\Users\hp\Desktop\MY_MAP.shp');
lat_grid2=ltln(:,1);
lon_grid2=ltln(:, 2);
Z=ltln(:, 3);
[lon_si, lat_si] = meshgrid(...
linspace(min(lon_grid2),max(lon_grid2)),...
linspace(min(lat_grid2),max(lat_grid2)));
m_alli = griddata(lon_grid2,lat_grid2,Z, lon_rmsi,lat_rmsi,'natural');
contourf(lon_si,lat_si,m_alli,15,'ShowText','on');
mapshow(S,'Color', 'black','LineWidth',2)
set(gca,'ColorScale','log');
colormap(flipud(jet(5)));
colorbar
geolimits([min(lon_grid2) max(lon_grid2)], [min(lat_grid2) max(lat_grid2)])
but command window shows me the error:
Error using geolimits (line 66)
Unable to use geolimits. Current axes or chart is not geographic.
Could you please help me?

use contourm() with 'Fill' option perhaps
contourf() is just contour() with fill, not a different computation

I am using these commands:
figure(6)
S=shaperead('C:\Users\hp\Desktop\MY_MAP.shp');
[loni, lati] = meshgrid(...
linspace(min(lon2),max(lon2)),...
linspace(min(lat2),max(lat2)));
mw_alli = griddata(lon2,lat2,Z,loni,lati,'natural');
[c,h]=contourm(lat_rmsi,lon_rmsi,mw_alli,12,'ShowText','on','fill','on');
hold on
geoshow(S,'Color', 'black','LineWidth',2)
colorbar;
scaleruler on
setm(handlem("scaleruler"), ...
"XLoc",21,"YLoc",36.5, ...
"MajorTick",0:200:600, ...
"FontSize",8)
setm(handlem('scaleruler'),'RulerStyle','patches')
But command window shows me:
Error using gcm (line 25)
Not a map axes.
Error in getm (line 80)
gcm(maphndl);
Error in scaleruler>scalerulerOn (line 89)
if strcmp(getm(ax,'mapprojection'),'globe')
Error in scaleruler (line 57)
h = scalerulerOn(s,gca);
which is the mistake? How could I modify my code in order to work?
