javascript - maintain distance between axis ticks in d3 chart -


i trying draw chart using d3-js. want x axis values [0.25yrs; 0.50yrs; 1yr; 2yrs; 5 yrs; 10yrs; 15yrs; 20yrs; 30 yrs; 50 yrs]. can done using d3's tickvalues() & tickformat() functions. need maintain distance between 0.25, 0.50 & 1 year ticks, because values belong these years & more distance between them reduce overlapping of drawn circles.

the tick position need : enter image description here

you can see distance between .01 , .02 in above image. how can that?

you need implement custom scale maps input range non-uniform output range. can give scale axis , draw ticks accordingly.

you have @ scales d3 provides if close enough want (a log scale maybe?), if can't find have no choice implement own.

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...
