Hi, I want a funtion graph in android.
I have two arrays (x e y) and want graph with draw line, but throws me
an error "the application has stopped unexpectedly ". I probe drawline
one to one and works
protected void onDraw(Canvas canvas) {
int [] datx= {30,40,60,80,100};
int [] daty = {20,60,90,60,100};
/*canvas.drawLine(datx[1],daty[1],datx[2],daty[2] ,paint);
canvas.drawLine(datx[2],daty[2],datx[3],daty[3] ,paint);
canvas.drawLine(datx[3],daty[3],datx[4],daty[4] ,paint);
*/
for(int i=0; i<=daty.length; i++){
canvas.drawLine(datx[i],daty[i],datx[i+1],daty[i+1]
,paint);
}
}
