MATLAB: How get rid of the white section

imageplot

how to display the whole image in the background
without white section ?
my intention is to plot the points directly on the background ( see the image)
y =[9; 9; 10; 9;  9; 9; 10; 9; 9; 10; 10; 10; 10; 10;9;9;9;9;9;9;10;10;10;10;10];
x =-[-5; -6; -4; 4; 5; 6; 1; 1; 3; -2; -1; 4; 6; -6;0;-1;-2;-3;2;-4;0;-3;-5;5;2];
hic =['Gelb  ';'Orange';'Braun ';'Gelb  ';'Gelb  ';'Gelb  ';'Orange';'Orange';'Grün  ';'Orange';'Orange';'Gelb  ';'Orange';'Orange';'Orange';'Grün  ';'Gelb  ';'Grün  ';'Gelb  ';'Gelb  ';'Orange';'Gelb  ';'Gelb  ';'Gelb  ';'Gelb  '];
h= gscatter(x,y,hic);
axis([-8 8 7 13]);
jgroup = h(1);
jgroup.Color = 'y';
jgroup.MarkerSize = 30;
jgroup = h(2);
jgroup.Color = [1,0.563,0];
jgroup.MarkerSize = 30;
jgroup = h(3);
jgroup.Color = [0.8500, 0.3250, 0.0980];
jgroup.MarkerSize = 30;
jgroup = h(4);
jgroup.Color = 'g';
jgroup.MarkerSize = 30;
hold on
ha = axes('units','normalized', ...
            'position',[0 0 1 1]);
% Move the background axes to the bottom
uistack(ha,'bottom');
% Load in a background image and display it using the correct colors
% The image used below, is in the Image Processing Toolbox.  If you do not have %access to this toolbox, you can use another image file instead.
I=imread('Auto_Raster.PNG');
hi = imagesc(I);
% Turn the handlevisibility off so that we don't inadvertently plot into the axes again
% Also, make the axes invisible
set(ha,'handlevisibility','off', ...
            'visible','off')

Best Answer

Before the axes() call:
set(gca,'color', 'none')
Also, you should be using
hi = imagesc(ha, I);
You moved ha to the bottom, so it might no longer be the "current" axes.
