GeodataLogger via Matlab with plot_google_map

I am working on a project which requires geodata logging via Matlab, I want it to plot big red dots when acceleration on z-axis goes above 410, and plot normal size blue dots when acc_z value is below 410. I am using plot_google_map function for plotting google maps image.

Here is my code:

lat = [48.8708 51.5188 41.9260 40.4312 52.523 38.274179];

lon = [2.4131 -0.1300 12.4951 -3.6788 13.415 27.074541]; 

acc = [333 327 405 ; 334 327 440 ; 327 323 412 ; 325 321 425; 325 320 430; 400 400 400];

acc_z=acc(:,end);

i=1:length(lat);

k=1:length(lon);

j=1:length(acc_z);

raw_data=[lat ;lon ;acc_z'];

raw_data_acc=raw_data(3,:);

for m=1:length(j)

     if (raw_data_acc(j))>410   
         plot(lon,lat,'.r','MarkerSize',40) 
         hold on 
     else
         plot(lon,lat,'.b','MarkerSize',20)
     end
  end
  plot_google_map

and here is my plot:

as you can see 2nd,3rd,4th and 5th dots must be big,red. But unfortunately i am not able to plot them as i want.

Any kind of help is appreciated.

I think your whole script can be replaced by this:

lat = [48.8708 51.5188 41.9260 40.4312 52.523 38.274179];
lon = [2.4131 -0.1300 12.4951 -3.6788 13.415 27.074541]; 
acc = [333 327 405 ; 334 327 440 ; 327 323 412 ; 325 321 425; 325 320 430; 400 400 400]; 
                                                       %   
% Get indices 3rd column of acc values greater than 410: 
bigthan410 = acc(:,3)>410;
                                                       %
% Plot the big ones as big red dots: 
plot(lon(bigthan410),lat(bigthan410),'.r','MarkerSize',40) 
hold on
                                                       %
% Plot the non-big ones as smaller blue dots: 
plot(lon(~bigthan410),lat(~bigthan410),'.b','MarkerSize',20)
                                                       %
plot_google_map

works like a charm, thank you so much.
