Anybody working on a Smith chart
« on: July 02, 2015, 09:39:30 am »
Hi,

if anybody is interested in programming a Smith chart (used for display of complex numbers, like impedances), I can hand-over my full well-tested Delphi pascal source code. It is quite beautiful, but not yet object-oriented. Would be nice of course to merge it into the Tchart.

Bye Stephan

No, I am not working on Smith charts, but why don't you post your code?

In principle, I do not see a reason why it should not be possible to add this to TAChart. The main obstacle seems to be that TAChart has perpendicular axes, but you can hide them and draw all the circles and labels in the chart's events - see http://forum.lazarus.freepascal.org/index.php/topic,16977.msg93141.html#msg93141 or http://forum.lazarus.freepascal.org/index.php/topic,27248.msg168240.html#msg168240.

I just started looking for plotting a Smith chart, because I'm trying to update PUFF to be cross platform and update its graphics.

It would be helpful here!
