I have a 90x125 matrix, when using image command, the program always start to plot at x=0 y=0. Can I change it to somewhere like x=-50 y=-50. Thank you

Check varying XData & YData for the Image object that you have created. It is about changing the X & Y Offsets

Thank you very much. May I ask one more question.I have generated the following image from the matrix.The color is a little bit wrong due to the different between value ( 0 vs 6.8*10^7 and any value below 10^7 will be colored in blue)
Can I somehow change the colorbar to make the image more like this?
Again, Thank you. Best regard.
