Add periodically data update example for jvm-swing-javafx

[fmvin]

Please create an example for demonstrating plotting in realtime. For example math or rand function updates each second.
jvm-swing-javafx example is much preferable.

Ho @fmvin , this must be some trick with offscreen drawing of kind. Perhaps CardLayout can help.
Lets-Plot itself doesn't support incremental updates at the moment so, every time the data is updated a brand new plot object must be created.

[fmvin]

@alshan, Thanks a lot for clarification. There is no problem with creating new plot objects except an annoying chart blinking after each data update. Hope your proposal will be helpful.

[alshan]

BTW, just setting the color of the backing panel in your app to the same value as the color of the plot background can reduce blinking.

Trick with CardLayout works exactly as I expected. On first data update I show first card and push a new chart to the second card. On next data update I show second card and push new chart to the first card. And so on.

Wow, glad to hear!
Do you think you can share your solution?

[fmvin]

I dont think this is a solution. It's just a naive trick with obvious limitations. Much better if native support of dynamic chart update will be added to Lets-Plot lib or to kotlin wrapper.
