thanks to this post :
Get the correct position of a point in AndroidPlot
i manage to display a cursor near a point of my plot.
Now i want to remove this cursor from the plot.
First question : How can i do that ?
Second question : I found a trick not to see it by displaying it in a non visible area of the plot (-1,-1) But i can't update this in a long press event click on the ploy. Although i manage to do this in a button click. Is there an explanation?
Thank you
