Drawing vectors with arrow-heads.

Hi. This is really neat! I thought I’d try re-doing in @iooxa/article an RLC circuit simulator that I once wrote in Java. Here’s an image of the UI I had: . I’ve been able to set up the sliders, the displayed variables and the graphs. My question is, how do we draw vectors, i.e. lines with arrows on the ends? Thanks. (I tried defining defs and marker but couldn’t get it to work.)

PS- While we’re at it: Logarithmic axes for graphs?

Sounds great! Emailing…

PS - I got it mostly working the way I like! Just would like the vectors to look like vectors. Demo: https://hedges.belmont.edu/~shawley/physapplets/seriesrlc.html
