I want to draw with my mouse on a plane with help axes, because I cannot know at what exact coordinate my point will be drawn.

Does turning on the grid solve the problem?
grid on
Here are two demos that show how to display the cursor location when moving the cursor over axes

Perhaps put the tick marks at the origin?
ax = gca
ax.XAxisLocation = 'origin';
ax.YAxisLocation = 'origin';
