python - Mongo Insert Error - InvalidDocument - Key names must not contain the NULL byte -


when attempting insert following json document:

{   "cmd": "sync",   "deviceid": "applf4klr7xxxxxx",   "devicetype": "ipad",   "user": "jackxxxxx",   "\u0003\u0001j\u0000e\\ok\u00031102699800\u0000\u0001r\u000326\u0000\u0001s\u00030\u0000\u0001wx\u00033\u0000\u0001b\u00032\u0000\u0001\u0000\u0011ef\u00034\u0000\u0001g\u000332768\u0000\u0001\u0001\u0001\u0000\u0000vjm\u000326:4909\u0000\u0001\u0001\u0001\u0001\u0001\u0001": true }

into mongo collection - error " invaliddocument - key names must not contain null byte".

the structure representing log line generated while logging ms activesync post requests towards owa server.

question is: safest way escape special char , yet keep new structure / value close possible original.

the problem last field key contains lot of unicode characters (include null byte \u0000):

\u0003\u0001j\u0000e\\ok\u00031102699800\u0000\u0001r\u000326\u0000\u0001s\u00030\u0000\u0001wx\u00033\u0000\u0001b\u00032\u0000\u0001\u0000\u0011ef\u00034\u0000\u0001g\u000332768\u0000\u0001\u0001\u0001\u0000\u0000vjm\u000326:4909\u0000\u0001\u0001\u0001\u0001\u0001\u0001

the question want keep unicode in field key? if not try like

.decode('unicode_escape').encode('ascii','ignore'))

taken this answer.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
