(Highcharts) Polar wedge/floating pie segments -


i trying make chart shows last 30 minutes of wind direction, recent reading on top of others. each reading should 90-degree pie segment, centered on wind angle, plotted on 360-degree polar chart.

it should divided 12 segments, labelled l, instead of 0-360. segments show; not want corral data them, normal wind rose or column chart. think guy looking similar functionality: (highcharts) circle/wedge areas in polar chart

i have image here show i'm trying achieve; plotted in php: http://futurshox.net/tmp/wind-dial-demo.png in example image, older readings successively more transparent go in time, last few readings stand out. i'm not desperate transparency, colour control nice.

here's showing how far i've got... http://futurshox.net/tmp/wind-dial-demo2.png best can come use scatter plot larger dots more recent readings, , place older ones closer middle. i've got 12 segments can't figure out how re-label them; if can.

is of possible? thank reading!

to relabel use xaxis.labels.formatter , set exact number of labels use tickinterval.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
