      Hi,

      @WLOrion said in Introduction in Qwt:

      I didn't know this behavior of the Qwt Classes.

      This is nothing Qwt specific, it's part of the C++ basics.

      As for tutorial, there's a nice online book that is in German but the author claims that online translator should give you a good enough result in your own language.

      Hi and welcome to devnet forum

      qwt is an extension of Qt as third party library. It maintains its own mailing list. Please check out there. This might be a faster way to get feedback on the issue.

      @mrjj
      Thank you sir for helping me and direction. I am able to solve this issue by

      setting the clipping area properly on graph. Use QWidget::update() instead of QWidget::repaint().

      @Yash001
      Hi, i wish i knew the answer
      but im fairly sure canvas()->width(); just returns the actual widget size and
      not the zoomed area as such.

      Had a look in the help but didnt find the answer on how to get the extent on a zoomed canvas.

      hmm, not sure about that one... I think I did, but I know I've been putting this laptop into suspend often because it's not the fastest pc I have :-)

      Anyway, I found this on https://help.ubuntu.com/community/EnvironmentVariables

      Shell config files such as ~/.bashrc, ~/.bash_profile, and ~/.bash_login are often suggested for setting environment variables. While this may work on Bash shells for programs started from the shell, variables set in those files are not available by default to programs started from the graphical environment in a desktop session

      So I didn't test any further.
