Topic: How to make graphs smoother?
I realized that graph lines has sometimes some block elements, e.g. see blue line of image "Capture1.PNG".
Desmos.com for example is adjusting the graph drawing so it is always smooth. See "Capture2.PNG".
I think it has to do with the - how i call it - "drawing step" or drawing distance, I guess it should be smaller in general - or at least if zoomed in.
