    I'm making a scientific calculator and I'm looking for a proper way to implement rectangular coordinare system and graphs. Requirements are following.

    1. x,y axis lines and grid (If those are not supported, I can implement them myself)
    2. Somthing like this : drawPixel(x, f(x))
      Coordinates can be a double value, And I will use this function to draw a graph.

    What would be the best choice?

        QCustomPlot might also be an alternative.
