Cannot get the size of a ChartDataPointsCollection

[QuentinSup]

I use Spire.Office for Java 4.10.5

I've noticed that it is not possible to get the size of a ChartDataPointsCollection.

So it is not possible to access get() without potentialy throwing an Exception...

Code: Select all

chart.getSeries().get(0).getDataPoints().get(1); // Could trigger an Exception because we don't know the size of the collection
