How can I get pixels info like the function "impixel", but for multiple pixel?

I want to get a plot of RGB info as a function of location (x,y), by drawing a line. (In impixel I need to choose one pixel, but I want a line of pixel)

Thank you.

 plot(squeeze(image(:,column,1)),'r')
 hold on
 plot(squeeze(image(:,column,2)),'g')
 plot(squeeze(image(:,column,3)),'b')

 xlabel 'Column nmumber'

 figure

 plot(squeeze(image(row,:,1)),'r')
 hold on
 plot(squeeze(image(row,:,2)),'g')
 plot(squeeze(image(row,:,,3)),'b')

 xlabel 'Row nmumber'

Hi lain, thanks for the answer! Actually I meant to draw a line with the mouse and get the info that in the pixel that are in the line.
