Hi Frederic,

If you want to contribute a fix for these two issues, along with appropriate unit tests, then please go ahead. I don't know of any technical reasons that would get in the way. I looked at the history of this bug, and there is nothing unusual about it. They are just two of many P4 bugs that never bubbled up high enough in priority to fix.

Thanks.

Hi,

At the moment, adding samples with a Y value equal to Double.NaN to an XYChart 
with ValueAxis results in graphs with crippling issues, already well documented:

LineChart / AreaChart Series : gap in line / area when using NaN or null as 
value
https://bugs.openjdk.java.net/browse/JDK-8092326

[ValueAxis] AutoRanging: Ignore NaN and null for internal calculation of 
dataMaxValue and dataMinValue
https://bugs.openjdk.java.net/browse/JDK-8091757

Both of these enhancement requests are quite old and in one instance it seems a 
patch was even proposed, but apparently they kept being postponed for years.

I'd be happy to contribute a PR to try and address these issues, but before I 
start doing anything, I'd like to know if there are any specific reasons, 
technical or other, for the tickets above to have been postponed like that for 
so long (especially for JDK-8092326 where code was proposed).

Thanks!

Frederic Thevenet
