Question

GraphView graph = (GraphView) findViewById(R.id.graph);
GridLabelRenderer gridLabel = graph.getGridLabelRenderer();
gridLabel.setHorizontalAxisTitle("Dates");
gridLabel.setVerticalAxisTitle("Status");

for (int i = 10; i >= 1; i--) {
    Calendar pastDate = Calendar.getInstance();
    pastDate.add(Calendar.DATE, -i);
    String beforedate = pastDate.get(Calendar.DATE) + "/" +(pastDate.get(Calendar.MONTH) + 1) + "/" + pastDate.get(Calendar.YEAR);

    Log.i("paste date is:", beforedate);
}

嘗試這個

gridLabel.setHorizontalLabels(new String[]{"1/1/1970", "1/2/1970", "1/3/1970"});
