Matlab - how to draw scaled figures on an image

I have an image with 4 spots on it, I want those spots to line up exactly(or very close) to X,Y coordinates in a figure 开发者_运维知识库that I would like to draw on top of this image. The image is currently 600x600 pixels, but that could be adjusted.

My figure scale goes from

AXIS([388020 388090 5776940 5777010])

How can I align my image to match that? So matlab draws on top of it?

Here is my matlab script, running this I can see the matlab drawing but no image underneath... and the matlab drawing seems to be inverted.

%takes in csv file %for each line outputs an image that includes 3 circles and the estimated %point

d = size(dataAdjusted) length = d(1)

for i = [1:1]

%# read and display image
img = imread('hciLab_N.png');
figure('Visible', 'off'),imagesc([388020 388090], [5776940 5777010], img);    

%# make sure the image doesn't disappear if we plot something else
hold on

%axis([388020 388090 5776940 5777010]);

%location estimation
yCoord = dataAdjusted(i,2)
xCoord = dataAdjusted(i,3)

%first  circle y, x, radius
c1Y = dataAdjusted(i,4);
c1X = dataAdjusted(i,5);
c1R = dataAdjusted(i,6);

%second circle y, x, radius
c2Y = dataAdjusted(i,7);
c2X = dataAdjusted(i,8);
c2R = dataAdjusted(i,9);

%third  circle y, x, radius
c3Y = dataAdjusted(i,10);
c3X = dataAdjusted(i,11);
c3R = dataAdjusted(i,12);

You can call both image() and imagesc() with x,y limits which are then used as the axis limits:

data = makeImage();
image([x0 x1],[y0 y1],data);
axis('xy');

or, if you just need scaled data:

data = makeData();
imagesc([x0 x1], [y0 y1], data);
axis('xy');
colorbar;

You may need to issue a 'hold all' once you've put up the image, before ploting anything else.
