Highcharts usage === some problem records and highcharts Problems

Question 1:

The chart is not displayed (but chrome, IE, and Firefox are not displayed in Some browsers). This may be caused by some js Code problems on the front-end page. Highcharts compatibility is good. The problem I encountered was that I used it. replace (/T/, "") operations on the date in the database result in the above problem. In addition, it appears in Firefox, IE, but not in Google.

 

Question 2:

Invalid Date is displayed, probably because the Date is sorted in descending order when it is read from the database. To change to ascending order and convert the Date to Greenwich mean time, use Date. parse () in js to convert.

Note:

The data type in Highcharts is Number.
