Highcharts series.data数据类型限制？

Question

Is there a limitation on the "array" method, specifically an amount of data points required to have it work?

I was using it to display large volumes of data just fine, but when I lowered the amount of points I was plotting, it seemed to break, and only plot one point, with an incorrect X value.

When I switched to use the object notation for data points ( { x: new Date(), y: 100 } ) it worked just fine.

To clarify, the two notations seem to function differently with different amounts of data. The only thing different between the below example and my production code are the actual dates/values. Syntax is the same.

[[Date.parse(i1), 100], [Date.parse(i2), 100]]

[{ x: Date.parse(i1), y: 100 }, { x: Date.parse(i2), y: 100 }]

Answer 1

The difference, as far as I can say, is that in the array notation, the Date object is not properly interpreted.

Using actual time stamps, both notations work the same.

Neither method should be affected by too few data points.
