QWTdial inverted range

[jmsbc]

Hi, I tried to invert the range on the speedometer in the dials example by doing:

d_speedo->setRange(240.0, 0.0);

This shows the speedometer values as 240 down to 0 on the display, but the needle doesn't change. How am I supposed to correctly set the qwtDial range to count down instead of up? Thanks

Dials with counter clockwise scales are not possible out of the box ( on my TODO list since some time ). At the moment I'm afraid you need to write some ugly code, that maps 240 to 0 and v.v.
