How to plot graph in java and to save as Image

Question

I would create a java program to save a graph as image PNG for example with the following data:

x-axis: 01  02  03  04  05  06  07  08  09  10 
y-axis: 610 635 659 680 699 712 722 732 736 749

Your question is very broad meaning you're likely coming here too soon in your development process. I suggest that you break the big problem into small constituent steps and then try to solve each single step one at a time. Come back with your specific answerable question and your code if stuck after attempting this. — Hovercraft Full Of Eels, Apr 17 '16 at 18:40

Theoretically you'd do that following these steps. Actually you have to first learn how to work with particular parts:

Save these coordinates to an array or a List.
Draw the content using javafx or any graphics library.
Read the: https://community.oracle.com/thread/2450090?tstart=0
In case of using javafx, you can capture its canvas with canvas.snapshot(..)
Save the file using ImageIO.write(SwingFXUtils.fromFXImage(wim, null), "png", file);
Hooray!

I recommend you to start with learning all about variables, data types, arrays, loops and lists/maps. Don't start with 2D drawing unless you can handle with data :)

provided great source of information to start with javafx – yash Aug 28 '18 at 08:59 — yash, Aug 28 '18 at 08:59

Try dotty.exe to create graphs. Use graphviz open source.
