[英]In HighCharts, how can I make the color for each plotted point in an array dependent on a value in a corresponding array?
[英]How can I hide (make invisible) a single plotted point in GNU Octave?
# simulate your drawellipse
plot(1:5, "-ro")
# get handle of line object
h = findobj (gcf, "type", "line")
# remove last point from xdata
set (h, "xdata", get(h, "xdata")(1:end-1))
