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
