I have created a dynamically generated timeline using php. The data generation is always the same, but for a specific set of date/times the data points do not appear on the chart.
- 29th April 2013 - 06:00:00 -> 1st May 2013 - 06:00:00 <--- Working
- 29th April 2013 - 06:00:00 -> 2nd May 2013 - 06:00:00 <--- Broken
from: Date.UTC(2013, 3, 29, 06, 12, 31),
to: Date.UTC(2013, 3, 29, 06, 17, 13)
Thanks to ssarabondo and Sebastian Bochan for suggestions. The issue has now been fixed. The problem was to do with a max limit of data points.
"When a series contains a data array that is longer than this, only one dimensional arrays of numbers, or two dimensional arrays with x and y values are allowed. Also, only the first point is tested, and the rest are assumed to be the same format. This saves expensive data checking and indexing in long series. Defaults to 1000."
Since my data sets are not going to be larger than 10,000 I changed the "turboThreshold".
I dont think this is advisable when working with much larger data sets though.
And thanks to all who offered some help.
