Hello everybody,

I have a big problem I want to draw a correlation line. I put on the two axis two diffrent parameters for example the maximal capacity and the maximal energy of batteries and these two parameters have a positive correlation and I want to draw this correlation into the graphic as a line.

    Why don't you use the standard series chart and sort before hand?

    Anyway - i assumen it is for your bachelor thesis: connecting points is not scientific. You might prefer a scatter plot

    thank you but you did not understand what I meant.
    I show you the graphics as an example. I want to create something like the first graphic and my graphic is the second one.
    You see the straights, I want to create such straights.

    So what you want to add is a linear regression ("Ausgleichsgerade") instead of connecting those points.

    Mh... I'll think about it

    Okay, you could either build a model inside rapidminer, and apply it on data you create.
    This is somehow a bit complicated to go for. Maybe gnuplot is a viable option here. The Series extension has a write gnuplot operator (which i've never used so far).
