Point Size on a Line Series?

[TerenceD]

Hi! I've successfully created the kind of chart I want (thanks to the example here). My only complaint is that the size of the plotted points are really small. I cannot figure out how to make them larger. Anyone know?

Here's my chart (with the points being too small):

And here's the code I use to generate the chart:

	auto *series = new QtCharts::QLineSeries();
	series->append(0, 6);
	series->append(2, 4);
	series->append(3, 8);
	series->append(7, 4);
	series->append(10, 5);
	*series << QPointF(11, 0) << QPointF(13, 3) << QPointF(17, 6) << QPointF(18, 3) << QPointF(20, 2);
	series->setColor(Qt::darkBlue);
	series->setPointsVisible();

	auto chart = new QtCharts::QChart();
	chart->layout()->setContentsMargins(0, 0, 0, 0);
	chart->setBackgroundRoundness(0);
	chart->legend()->hide();
	chart->addSeries(series);
	chart->createDefaultAxes();

	auto chartView = new QtCharts::QChartView(chart);

I don't have QtCharts installed, but since QLineSeries inherits from QXYSeries, it has
setPen(const QPen &pen) function.

series->setColor(Qt::darkBlue);
series->setPen(QPen pen(Qt::darkBlue, 3);

Thanks, Dream Captain. Ideally, I would like to be able to just leave the line size the same and increase the point size but making the pen size thicker does help. Examples:

Here it is at a pen size of 2:

Here it is at a pen size of 3:

I think I'm going to go with a pen size of 2.

Thanks again.

Is it possible to increase the points size without increasing the line width?

Hi @QueenAI, Did you find the answer? Even I am looking for the same solution.

I solve this problem by drawing QLineSeries and QScatterSeries at the same time. Init a QPointF and append it into both line series and scatter series. Then add both series into chart.
