amcharts与轨道 - 不敛数据反馈
问题描述:
我正在以下:http://railsontherun.com/2007/10/04/sexy-charts-in-less-than-5-minutes/amcharts与轨道 - 不敛数据反馈
我经历过这一切进展相当容易,但随后与图表查看网页时,它加载(闪光灯)一个黑色的矩形错误:
“错误加载文件http://localhost:3000/reports/population.xml”
有人在评论中说,这可能与在XML构建文件中的代码来完成。
xml.instruct! :xml, :version=>"1.0", :encoding=>"UTF-8"
xml.chart do
# xml.message "You can broadcast any message to chart from data XML file", :bg_color => "#FFFFFF", :text_color => "#000000"
xml.series do
@cities.each_with_index do |city, index|
xml.value city.name, :xid => index
end
end
xml.graphs do
#the gid is used in the settings file to set different settings just for this graph
xml.graph :gid => 'population' do
@cities.each_with_index do |city, index|
population = city.population
case population
# When the population is > 1 million, show the bar in red/pink
when > 100000
xml.value value, :xid => index, :color => "#ff43a8", :gradient_fill_colors => "#960040,#ff43a8", :description => level
else
xml.value value, :xid => index, :color => "#00C3C6", :gradient_fill_colors => "#009c9d,#00C3C6", :description => level
end
end
end
end
end
我不完全确定错误来自哪里,但我很乐意提供任何帮助!
最佳, 埃利奥特
答
我在该行想通了这一点
xml.value value, :xid => index, :color => "#00C3C6", :gradient_fill_colors => "#009c9d,#00C3C6", :description => level
,第二个 “值” 和 “级别” VAR没有定义。一旦它们全部起作用。
