python - scrapy how to import the settings to override it -


this code

class test(spider):     self.settings.overrides['jobdir']= "seen"

i got:

  file "c:\python27\lib\site-packages\scrapy\spider.py", line 46, in settings     return self.crawler.settings   file "c:\python27\lib\site-packages\scrapy\spider.py", line 41, in crawler     assert hasattr(self, '_crawler'), "spider not bounded crawler" assertionerror: spider not bounded crawler

i extending spider , not using crawler because don't have links nor rules follow

i guessing problem because didn't import settings , need please

in order change settings in spider can:

class testspider(spider):      def set_crawler(self, crawler):         super(testspider, self).set_crawler(crawler)         crawler.settings.set('jobdir','seen')      # rest of spider code

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 .
