Beginners' Questions Function plotter issue while plotting sinus

    Hello,Β 

    I am currently writing my master's thesis. In this thesis I have to plot a function graph, which consists of several sin in a row. When using the function plotter I get an unexpected behaviour.

    I have created a rectangle for the function plotter as requested, in which the function is drawn and I clicked on it before I called the function plotter. (Image 001)

    If I then let the function draw with 10 sine in the rectangle, the amplitude of the sine increases more and more and the lines become thicker and thicker. (Image 002)

    What am I overlooking in the settings?Β 

    Thanks in advance for your help.

    Greetings

    Florian

    Hi, I'd suggest checking the box: "calculating the first derivative numerically". Alternatively change the first derivative to cos(x). (I recall a similar issue was experienced was posted on GitLab https://gitlab.com/inkscape/extensions/-/issues/273)

    Hello,Β 

    thank you very much for your reply. Ticking the option "calculating the first derivative numerically" solves this problem. Thank you also for providing me the post on GitLab. Now i can understand why this problem occurs.

    Best Regards,

    Florian
