how can I change worldmap axes grid and label?

Hi, I am trying to make a map with spesific lat and lon degrees. And I want to make labelling and grids on 26 E, 29 E, 32 E, 35 E,38, E41 E,44 E. But whatever I tried the labelling and grid never start from 26 E. I add my result picture below. Please help me.

clear all 
close all
clc

xmin = 26;
xmax = 44.6;
ymin = 34;
ymax = 42.5;

latlim = [ymin ymax];
lonlim = [xmin xmax];

w=worldmap(latlim,lonlim)

p=findobj(w,'Tag','Parallel');
m=findobj(w,'Tag','Meridian');
p.LineWidth = 1.5;
p.Color='red';
m.LineWidth = 1.5;
m.Color='red';
bordersm('Turkey')
bordersm('Cyprus')

Use setm to set the meridian line & label locations ('MLineLocation' and 'MLabelLocaton' properties).

Also, you can use gridm to set your grid properties.

xmin = 26;
xmax = 44.6;
ymin = 34;
ymax = 42.5;

latlim = [ymin ymax];
lonlim = [xmin xmax];

w=worldmap(latlim,lonlim);

setm(gca,'MLabelLocation',26:3:44,'MLineLocation',26:3:44)
gridm('GLineWidth',1.5,'GColor','red')

Thank you, this is exactly what I needed.
