Hello everyone. Has the TChart functions to plot TPolarSeries in C++ Builder 10.1 Berlin Architect ? It seems like inluded TeeChart component is limited somehow. I need to plot antenna characteristic and I need to use polar plot. Thanks in advance

You could use a X-Y chart and draw the polar plot with to functions, one with angle from 0 to 180 degrees and second from 180 to 360 degrees. x = r*cos(alpha), y = r*sin(alpha), see https://en.wikipedia.org/wiki/Polar_coordinate_system for details.
