Highcharts

问题 On my chart I am trying to change the start point for my graph but does not work: series: [{ name: 'Difficulty', connectNulls:true, color: '#FF0000', pointInterval: <%= 1.day * 1000 %>, pointStart: <%= 2.weeks.ago.at_midnight.to_i * 1000 %>, data: [<% HomeworkStudent.where(:school_user_id => current_user.school_user.id).order('updated_at ASC').each do | homework_student| %> [Date.parse(<%= homework_student.updated_at.to_json.html_safe %>), <%= homework_student.difficulty.to_json.html_safe %>]
