JavaFX AreaChart Clear Data

Question

i create a Object of a extended Area Chart. In this Area Chart is a dataSerie if the object is created. Later i will add 3 New Data Series to the Area Chart and the first dataSerie musst be deleted.

How can i delete the first dataSerie?

areachart.getData().addAll(s1, s2, s3);

Here you can see how i add the new Series into the areachart, but first i want to delete the old ones...

Thanks for your help

---

So now I know it! I can use the following Statement:

areachart.getData.remove(....)

But this makes another Question open! How can i get the total added Series of the Area Chart. How can I get the information of how many series in the Area Chart are?

Solution

I fixed the problem by myself. You can do something like this:

areachart.getData().removeAll(m_histogram.getData());

It will remove all kind of data inside the area chart!!

Someone please answer it.

getData() returns an ObservableList of Series, so you can call any method defined in ObservableList or in List, such as clear(), size(), etc

Its already enabled.

And I have 8.8.8.8 in my resolv.conf. Should it be something else, if yes then how should I determine what it should be?

@Lokesh ok, can you disable it (proxy_dns) and try without it

[Lokesh]

I tried that too. It didn't work out.
