[BUG] Graph does not rescale correctly when mimimizing or maximizing window.

[hansonry]

Describe the bug
It's in the title.

To Reproduce
Steps to reproduce the behavior:

1. Run an example.
2. Maximize the window.
3. Notice the graph doesn't rescale correctly.

Expected behavior
The graph should rescale along with the lines.

Screenshots
Running the line_chart example.

At launch:

After maximizing and minimizing:

Desktop (please complete the following information):

• OS: Linux
• Godot Engine Version: 4.3
• Plugin Version: v24.05.06

Additional context
Seems like the root cause is that get_rect() (being called inside BoxPlot.get_box() and BoxPlot.get_plot_box()) doesn't update right away. So some parts of the redraw are scaled incorrectly.

I think I fixed it by adding this code to box_plot.gd:

func _on_resized() -> void:
	$GridBox.queue_redraw()
	for function in $FunctionsBox.get_children():
		function.queue_redraw()

_on_resized is connected to the BoxPlot resized signal.

This seems to fix the issue. I have no idea if this is the correct way to fix it or if it is the most efficient. I am not even clear on why this is necessary, seems like it would make sense for Godot to not call queue_redraw() until all the parents are updated. I probably don't understand the code well enough. Anyway, I hope this is helpful!

Thanks for your fix! Personally I prefer to add the following code directly to res://addons/easy_charts/control_charts/chart.gd and connectd to PlotBox resized signal:

func _on_plot_box_resized() -> void:
	grid_box.queue_redraw()
	for function in functions_box.get_children():
		function.queue_redraw()

Would you like to create a PR for that?
