GraphView 中的虚线

Dotted dash line in GraphView

我要虚线,如the official documentation:

    futureSeries.setDrawDataPoints(true);

    Paint paint = new Paint();
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(10);
    paint.setPathEffect(new DashPathEffect(new float[]{8, 5}, 0));
    futureSeries.setCustomPaint(paint);

    graph.addSeries(futureSeries);

build.gradle:

   compile 'com.jjoe64:graphview:4.2.1'

结果不是虚线:

像这样就可以了:

只需申请LineGraphSeries#setDrawAsPath(true).

Paint paint = new Paint();
paint.setStyle(Paint.Style.STROKE);
paint.setStrokeWidth(10);
paint.setPathEffect(new DashPathEffect(new float[]{8, 5}, 0));

LineGraphSeries<DataPoint> series = ... // init

series.setDrawAsPath(true);
series.setCustomPaint(paint);

graphView.addSeries(series);

结果:
