Attached is an example that uses BitmapCreator to create a similar graph.
Note that BitmapCreator will be included as an internal library in the next version of B4J to make it easier to use.
You will need to replace it with the class.
Erel, thank you very much, it is exactly what I needed, but still I have some questions.
Is it possible to put numbers on a scale (for ex. voltage on y-axis and time on y-axis)?
How can I change the grid itself? ( ex. 10x10 20x20)
Can it show the coordinate when hovering a cursor over the graph?
Can I change the scale of the graph on axises while it is building?
In this implementation it only draws the text when there is enough room for the complete label. It can be further improved to make it appear immediately.
