I have this code for plotting circles around GPS stations, it works fine, but when I plot the map and try to plot those stations on the map, it doesn't work. I don't understand why.
clc
clear all; close all;
scriptPath = 'D:\Data\Matlab_scripts\';
GPS_LOC_dir = 'D:\Data\GPS_stations\';
% % This part read the GPS stations information
GPS_station_file =[GPS_LOC_dir 'GPS_Stations.txt'];
delimiter ={'\t',' '};
startRow = 2;
formatSpec = '%s%f%f%[^\n\r]';
fileID = fopen(GPS_station_file,'r');
dataArray2 = textscan(fileID, formatSpec, 'Delimiter', delimiter,'HeaderLines' ,startRow-1, 'MultipleDelimsAsOne', true, 'EmptyValue' ,NaN, 'ReturnOnError', false);
fclose(fileID);
CODE2 = dataArray2{:, 1};
LAT2 = dataArray2{:, 3};
LON2 = dataArray2{:, 2};
% This is the part that draws the Indian map.
whitebg('w');
load coast
m_proj('mercator','long',[68 98],'lat',[0 30]);
axesm('MapProjection','mercator','MapLatLimit',[0 30],'MapLonLimit',[68 98]);
framem
m_coast('patch',[0.7 0.7 0.6]);
m_grid('xtick',12,'ytick',8);
xlabel('Longitude (deg)');
ylabel('Latitude (deg)');
% End of map plot
rad = km2deg(100,'earth');
n = length(LAT2);
r = ones(n,1)*rad;
c = [LON2,LAT2];
plot(LON2,LAT2,'r*');
text(LON2,LAT2, CODE2 ,'fontsize',10,'fontname','times','fontweight','bold');%
hold on
[h,xs,ys] = circles(r,c,'color','g','lineWidth',2);
hold off
it shows only the map, the circles and the stations vanishes.
Without the map codes, I get everything right. But introducing the map, I get only the map.
Can anyone help ? Thanks, Add.

"Without the map code" - which is the "map code"? Please format your code peroperly using the "{} Code" button.

You should not try to combine plot() and the mapping toolbox on the same axes. The mapping toolbox set up unusual axes properties that plot() does not know about. Instead of plot() you should use plotm()

Thanks Roberson. But using plot(m) is not helping. In other cases, using mapping toolbox it works, but I want a solution such that I would be able to plot this without the mapping toolbox.

I suspect you should not call axesm or framem if you're also using m_map functions.
Where'd you get the circles function? If it's mine, check the inputs. My circles function takes inputs in the form circles(x,y,r), but it looks like you're entering circles(r,[x y]).

I am not using your circles function. The problem is with the map boundary, it calls its axis and other axes are suppressed.
Thanks
