If no x values are given for the points in a series, pointInterval
defines the interval of the x values. For example, if a series
contains one value every decade starting from year 0, set
pointInterval
to 10
. In true datetime
axes, the pointInterval
is set in milliseconds.
It can be also be combined with pointIntervalUnit
to draw irregular
time intervals.
If combined with relativeXValue
, an x value can be set on each
point, and the pointInterval
is added x times to the pointStart
setting.
Please note that this options applies to the series data, not the interval of the axis ticks, which is independent.
