Problem of reactivity between the click position and the parameter values in the table
It is often necessary to click several times on a pixel to get the parameter values in the table.
To limit problems and to improve readability, it would be advisable to limit the number of registered coordinates, because if the user clicks many times, it is difficult to remember in which order the clicks were made.
It would probably be advisable to register only two positions: the current position and the previous one. Furthermore, to better distinguish these two positions, the two circles could be displayed in two different colors, for example in green for the current position and in red for the previous one.
