Legends and x axis missing visually

[Fu HSien]

Please note that I am using version 1.7
I am creating a graph with 3 series and with the function of turning off the series.
I have created a simple code to ensure that it works. Please check this: jsfiddle
However, when I implement into my actual code (there will be thousands – ten thousands data points), there are some weird behaviors observed.
1) Whenever I enabled legend, the X axis disappeared:
2) Instead of showing 3 series in the legend, it only displays one of them
3) Even if the remaining 2 series is not displayed on the legend, I can still click it to hide/unhide the series

Update:
I realize the problems occur when there the number of points is significantly big, to an extend that the marker will not be shown on graph.
New jsfiddle
Please try increase the limit to a higher number to see the problems.
I would deeply appreciate any help provided!

Thank you.
