Hello, I am trying to configure a colorbar but there are two information that I don't know how to do.

This is the image of my plot

In addition, I am adding the code below:

function [ ] = Figure1(TT,aux,x,y)
      set(gcf,'Color',[1 1 1]);
      h=colorbar('SouthOutside');
      set(h, 'Position', [.05 .15 .9 .05]);
      load('MyColormap.mat')
     if aux == 1
        subplot('Position',[.0 .25 .20 .20]);
     elseif aux == 2
        subplot('Position',[.25 .25 .20 .20]);
     elseif aux == 3
        subplot('Position',[.5 .25 .20 .20]);
     else
        subplot('Position',[.75 .25 .20 .20]);
     end
      shading flat
      pcolor(x,y,TT')
      colormap(mymap)
      caxis([275 320])
      shading interp
      view(2)
      axis square
      set(gca,'Visible','off')   
  end

What I need:

Define (reduce) the space between subplot(1,4,1) e subplot(1,4,2) .....
Add a title on my horizontal colorbar.

PS: I have already read many links, but I couldn't find a concrete information!

Cheers

Mr Jonas, As I said before, I have already studied this function and I am studying again but it doesn't work with me!!

Could you give a complete example that the answer is a plot with 1 row and 4 columns with the circle closer than the default?

I create a vector with the position to plot the 4 circle. The image I am adding below.

And ha(1) = [0.0400 0.0300 0.2075 0.9400] ha(2) = [0.2775 0.0300 0.2075 0.9400] ha(3) = [0.5150 0.0300 0.2075 0.9400] ha(4) = [0.7525 0.0300 0.2075 0.9400]

How can I integrate the subplot(1,4,1) with ha(1)?

I don't know what it means to integrate subplot(1,4,1) with ha(1). See my answer below.

I'm just gonna sum up the comment chain as an answer for future reference.

Walter Robinson gave an excellent solution for dealing with axis placement without use of third-party functions (see question comments). The following example makes use of the FileExchange function tight_subplot ( link ). Similar functions are subtightplot ( link ) and subplot_tight ( link ). Syntax may differ depending on function.

%%Create 4 axes with zero gap and zero margins
ha=tight_subplot(1,4,0,0,0);
%%Plot 4 circles with zero space in between and remove any axis graphics
for i=1:4
  axes(ha(i));
  viscircles([0 0],1);
  axis square
  axis tight
  set(gca,'color','none','xcolor','none','ycolor','none')
end
