Thx for help in advance!

As fast solution, change yAxis as

yAxis:{ start:12400, end:12500, step:10 },

There is a problem in math of charts, they fail to calculate yAxis automatically for your dataset ( fixed version will be available in few days )

Hi,
I just do it according to your advice ,but I meet some problems . Firstly ,the values of yAxis

cann’t display completely , the values just show the first few digits . Sencondly, the linedata

come from database dynamicly, I cann’t set the yAxis value awalys, yAxis:{ start:12400, end:12500, step:10 , color :"CF1A1A" }
