QCustomPlot Discussion and Comments

bug with paintingReturn to overview

When I drag the graph in plot, it display new grid, new ticklabel, new ticksteplabel but the old one still remains. By the way, how to set substicks in this version?

You probably set the background color to transparent? Then you see the old render in the background.

hello Leoni
As u said, I do set the background to transparent. And this problem was solved when I change the background color. But new problem comes. How could I set background to transparent?

I am try to swap axis from example:

  demoName = "Quadratic Demo";
  // generate some data:
  QVector<double> x(101), y(101); // initialize with entries 0..100
  for (int i=0; i<101; ++i)
    x[i] = i/50.0 - 1; // x goes from -1 to 1
    y[i] = x[i]*x[i];  // let's plot a quadratic function
  // create graph and assign data to it:
  customPlot->graph(0)->setData(y, x);
  // give the axes some labels:
  // set axes ranges, so we see all data:
  customPlot->yAxis->setRange(-1, 1);
  customPlot->xAxis->setRange(0, 1);

and get wrong output.
The reason for this maybe QMap, which internally used for store data.
This bug in all versions of QCustomPlot. Please fix this bug...
