ZingChart: Show tooltip on large data set
When using a large data set, tooltips are automatically turned off for speed efficiency. To turn the tooltips back on for large data sets, you must set "max-trackers"
to a number higher than the number of nodes in your data set. "max-trackers"
is set inside the plot object.
I generally just make "max-tracker":9999
unless I am dealing with a data set with more than 9999 points.
Example of large data set turning off tooltips:
Here is a demo of how `"max-trackers"` works:
