surfaceview - Android onTouch multi-touch not receiving all touch events -


i using android surfaceview , listening multi-touch events. able detect multiple touches seems action_pointer_up touch event not getting fired. here quick snip of code.

public class gameview extends surfaceview implements runnable {     ...     @override     public boolean ontouchevent(motionevent motionevent) {         log.i("pointer count", integer.tostring(motionevent.getpointercount()));         return true;     }     ... }

when put 2 fingers on screen pointer count log out 2. if remove 1 of fingers pointer count log out not 1 , stays @ 2. goes 1 if move finger still on screen. why , how firkin fix it? thanks!

edit

this problem occurs on 1 plus 1 , friends samsung galaxy note 2. interesting when put on samsung galaxy s4 problem did not occur.

do not use getaction() == motionevent.action_pointer_up action contain pointer index.

getactionmasked() strip out information, , used comparison.

see http://developer.android.com/reference/android/view/motionevent.html#getactionmasked()

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
