hi i'm a student and i'm trying to make a website that will shows line
chart using an auto-generated json file using json_encode in php. The
layout of my json file is similar the follow:
[{"polso":"341","dita":"57"},{"polso":"237","dita":"70"},{"polso":"370","dita":"67"},{"polso":"367","dita":"72"},{"polso":"42","dita":"57"},{"polso":"264","dita":"57"},{"polso":"239","dita":"42"},{"polso":"239","dita":"42"},{"polso":"239","dita":"42"},{"polso":"233","dita":"51"},{"polso":"233","dita":"51"},{"polso":"233","dita":"51"},{"polso":"185","dita":"28"},{"polso":"185","dita":"28"},{"polso":"185","dita":"28"},{"polso":"214","dita":"39"},{"polso":"214","dita":"39"},{"polso":"214","dita":"39"},{"polso":"224","dita":"41"},{"polso":"253","dita":"28"},{"polso":"253","dita":"28"},{"polso":"253","dita":"28"},{"polso":"253","dita":"28"},{"polso":"179","dita":"36"},{"polso":"179","dita":"36"},{"polso":"179","dita":"36"},{"polso":"221","dita":"38"},{"polso":"221","dita":"38"},{"polso":"221","dita":"38"},{"polso":"182","dita":"36"},{"polso":"182","dita":"36"},{"polso":"182","dita":"36"},{"polso":"182","dita":"36"},{"polso":"161","dita":"40"},{"polso":"161","dita":"40"},{"polso":"161","dita":"40"},{"polso":"179","dita":"36"}]
where we have in each element, the name of value follow by the value. I
need to create a line chart with two lines one for 'polso' values and
another one for 'dita' values. On the X-axis i only need to have the total
number of json elements (37 in our sample json file). I Really need your
help because i never create a web chart and i need to finish my website for
the exams.
