I need to do some heat graphics with a legend bar next to it. I also need to place the axes. However, since I had to slightly increase the size of the chart so the legend bar appears on the side, the Y-axis shifts away from the chart's drawing. As we can see in the figure:
I would like the Y axis to be close to the picture, as the X-axis is! I'm using the image () function, is there any entry in this function that can move the axis without having to change the dimensions of the window?
