Draw using graph coordinates in android -


in android app, want draw circles , have find intersection points. , need draw lines between intersection points got. know how implement logic dont know draw graph.

i tried draw on mapview using geopoints, considered lattitude "x" axis , longitude "y"axis. not enough expected.(sometimes lines disappear when zooming).

which feature of android facilitate this? guide me implement this.

thanks in advance...

you want custom view. custom views allow draw canvas. canvas has functions drawline , drawcircle. takes x,y coordinates, 0,0 being upper left corner , x , y growing bigger go right , down. if don't want 0,0 upper left, can use basic algebra translate wherever want.
