autoScrollingDelta property
The number of data points to be visible always in the chart.
For example, if there are 10 data points and autoScrollingDelta
value is 5 and autoScrollingMode
is AutoScrollingMode.end
, the last 5 data points will be displayed in the chart and remaining
data points can be viewed by panning the chart from left to right direction. If the autoScrollingMode
is AutoScrollingMode.start
, first 5 points will be displayed and remaining data points can be
viewed by panning the chart from right to left direction.
If the data points are less than the specified autoScrollingDelta
value, all those data points will
be displayed.
It always shows the recently added data points and scrolling will be reset to the start or end of the range, based on autoScrollingMode property's value, whenever a new point is added dynamically.
Defaults to null
.
