How to change background color of legend?

[Mitul Vekariya]

Hey guys

First of all, thank you for offering such great tool.

Here's the problem: I am using pyqtgraph with white background. When I added legend to my graph, it has opaque black color. I tried a lot to find how to change the color property of legend, but all in vain. Is it possible to change the background of legend to white? 

Thanks

You might have already solved the problem... but i tried it.

The simplest way that i think is to edit the line 122 and 123 of "C:\Python27\Lib\site-packages\pyqtgraph\graphicsItems\LegendItem.py" (in the case of windows) or, something equivalent to it

as shown in the following code,

p.setPen(fn.mkPen(0, 0, 0, 255)) #  original -> p.setPen(fn.mkPen(255,255,255,100))
p.setBrush(fn.mkBrush(255, 255, 255, 255)) # original -> p.setBrush(fn.mkBrush(100,100,100,50))


, and the saving it. Then the background color of your legendItem should changes(and the frame clor should be black).
