void TrafficGraphDataTests::simpleCurrentSampleQueueTests()
{
    TrafficGraphData trafficGraphData(TrafficGraphData::Range_5m);
    for (int i = 0; i < TrafficGraphData::DESIRED_DATA_SAMPLES; i++)
        QVERIFY(trafficGraphData.update(TrafficSample(i, i)));

    TrafficGraphData::SampleQueue queue = trafficGraphData.getCurrentRangeQueue();
    QCOMPARE(queue.size(), TrafficGraphData::DESIRED_DATA_SAMPLES);
    for (int i = 0; i < TrafficGraphData::DESIRED_DATA_SAMPLES; i++){
        QCOMPARE((int)queue.at(i).in, TrafficGraphData::DESIRED_DATA_SAMPLES - i - 1);
        QCOMPARE((int)queue.at(i).out, TrafficGraphData::DESIRED_DATA_SAMPLES - i - 1);
    }

    QVERIFY(trafficGraphData.update(TrafficSample(0, 0)));
    queue = trafficGraphData.getCurrentRangeQueue();
    QCOMPARE(queue.size(), TrafficGraphData::DESIRED_DATA_SAMPLES);
    QCOMPARE((int)queue.at(0).in, 0);
    QCOMPARE((int)queue.at(0).out, 0);

void TrafficGraphWidget::paintPath(QPainterPath &path, const TrafficGraphData::SampleQueue &queue, SampleChooser chooser)
{
    int h = height() - YMARGIN * 2, w = width() - XMARGIN * 2;
    int sampleCount = queue.size(), x = XMARGIN + w, y;
    if(sampleCount > 0) {
        path.moveTo(x, YMARGIN + h);
        for(int i = 0; i < sampleCount; ++i) {
            x = XMARGIN + w - w * i / TrafficGraphData::DESIRED_DATA_SAMPLES;
            y = YMARGIN + h - (int)(h * chooser(queue.at(i)) / fMax);
            path.lineTo(x, y);
        }
