When running on Mac in Dark Mode with recent Qt versions, plots render like this:
Reproduction Steps:
The is produced by this code:
from numpy import linspace, sin
from traits.api import HasTraits, Instance
from traitsui.api import View, Item
from chaco.api import Plot, ArrayPlotData
from enable.api import ComponentEditor
class LinePlot(HasTraits):
plot = Instance(Plot)
traits_view = View(
Item('plot', editor=ComponentEditor(), show_label=False),
width=500,
height=500,
resizable=True,
title="Chaco Plot",
)
def _plot_default(self):
x = linspace(-14, 14, 100)
y = sin(x) * x**3
plotdata = ArrayPlotData(x=x, y=y)
plot = Plot(plotdata)
plot.plot(("x", "y"), type="line", color="blue")
plot.title = "sin(x) * x^3"
return plot
if __name__ == "__main__":
LinePlot().configure_traits()
Expected behavior:
At a minimum we should be defaulting to painting the padded area white so the labels are visible. Better would be to detect the background color of the window and adapt rendering appropriately (which would require a default "dark-mode" palette for all drawing, which is significant work)
