Hi,

Is it possible to make a color gradient over a single graph.

I took the expample from the tutorials, but how can I program a color gradient for an single graph?

// generate some data:

QVector<double> x(101), y(101); // initialize with entries 0..100

for (int i=0; i<101; ++i)

{

x* = i/50.0 - 1; // x goes from -1 to 1
y = x*x; // let's plot a quadratic function
}
// create graph and assign data to it:
customPlot->addGraph();
customPlot->graph(0)->setData(x, y);
// give the axes some labels:
customPlot->xAxis->setLabel("x");
customPlot->yAxis->setLabel("y");
// set axes ranges, so we see all data:
customPlot->xAxis->setRange(-1, 1);
customPlot->yAxis->setRange(0, 1);
customPlot->replot();
*

Many thanks for your help
