  3. public:
  4.     ScaleDraw ();
  5.     virtual ~ScaleDraw () {};
  6.  
  7.     virtual QwtText label (double value) const
  8.     {
  9.         QwtText ret_val = QwtText (QString::number (value));
  10.         ret_val.setColor (_color);
  11.         return ret_val;
  12.     };
  13.  
  14. private:
  15.     QColor _color;
  16. };
To copy to clipboard, switch view to plain text mode

Hi again, I think I triyed that solution before with no result.

Y create a similar code
Qt Code: 
  1. class NewDraw: public QwtScaleDraw
  2. {
  3. public:
  4.     NewDraw(QColor c)  {my_color = c;};
  5.       virtual QwtText label (double value) const
  6.       {
  7.           QwtText ret_val = QwtText (QString::number (value));
  8.           ret_val.setColor (my_color);
  9.           return ret_val;
  10.       };
  11.  
  12.   private:
  13.       QColor my_color;
  14. };
To copy to clipboard, switch view to plain text mode 

And when I want to chande de color:
Qt Code: 
  1. QColor c = QColorDialog::getColor( Qt::white, this );
  2.  
  3.     my_Plot->setAxisScaleDraw(QwtPlot::xBottom, new NewDraw(c));
To copy to clipboard, switch view to plain text mode 

But it doesnt work. Instead of changing the color of the numbers, all the numbers and ticks disappear. Any idea? Thanx
