[SOLVED] draw mathematical scheme

i want to draw a mathematical scheme to generate function's cruves ,
is there a widget that help in that ,i just use simple curves,

Hi,
I'm not sure I'm understanding you right, can you show an image of what you would like to achieve ?


@youzking Hi, there is http://www.qcustomplot.com/ – or if you want something puristic: Override the
paintEvent(QPaintEvent*)
method of QWidget and use QPainter.

thanks ,
i'll take a look about qcustomplot ,but i think , Overriding the *paintEvent(QPaintEvent) ** will help to make exactly what i want .

You also have the Qwt that might be of interest

yes , i installed it , it is interesting , !
but do it manually still the best solution , even it is little more complicatedthanks for ur help ^^
