How can I convert Python String to raw_value or Object value? -


i creating pages in scribus via scripting place text , images. wish use pyexviv2 read/write exif xpkeywords. reading fine using 'human_value' convert byte values returned. realise not need convert except see worked. splitting obtained string 1 tag , wish write 1 part tag. understand cannot use 'human_value' in reverse (read only). can point me in right direction please? below, progress far, obtaining 5th part of filename, works fine.

[edit] adding... metadata['exif.image.xpkeywords']=parts[4] write gives valueerror: invalid value.

#!/usr/bin/env python # -*- coding: utf-8 -*-  import scribus #will test scribus running import pyexiv2 import string  metadata = pyexiv2.imagemetadata('j:/book/banns/1.jpg') metadata.read()  metadata.exif_keys ['exif.image.imagedescription',  'exif.image.documentname',  'exif.image.xpcomment',  'exif.image.xpauthor',  'exif.image.xpsubject',  'exif.image.xpkeywords',  'exif.image.datetime',  'exif.image.artist',  'exif.image.copyright',  'exif.image.exiftag']  tag=metadata['exif.image.documentname'] txt=tag.human_value scribus.messagebox("", txt)     #instead of raw_value or value parts=txt.split(',',5)         #split filename @ ',' i.e. 5 strings in list scribus.messagebox("",parts[4]) #separate place list

after 4 hours research have through trial , error found working answer may useful others.

i added question... "metadata['exif.image.xpkeywords']=parts[4]" write gives valueerror: invalid value answer follows because xpkeywords utf-16...

metadata['exif.image.xpkeywords']=pyexiv2.utils.string_to_undefined(parts[4].encode('utf-16')) metadata.write()

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 .
