Grid Lines are drawn above the Candlesticks.

[shujaatak]

I have noticed that grid lines are drawn above the candlesticks like this:

In order to send the grid lines to back, I set the Z value to -1000 here:

finplot/finplot/__init__.py

Line 1847 in 1190e8a

ax.axes['left']['item'].setZValue(30) # put axis in front instead of behind data

and here too:

finplot/finplot/__init__.py

Line 1848 in 1190e8a

ax.axes['bottom']['item'].setZValue(30)

Now the grid lines appear behind the candlesticks like this:

But as you can see here:

finplot/finplot/__init__.py

Line 1847 in 1190e8a

ax.axes['left']['item'].setZValue(30) # put axis in front instead of behind data

there is this note:
put axis in front instead of behind data

I wonder what, if any, problems I might face if I set the Z value to -1000 to send the grid lines behind the candlesticks? Or is there any other recommended way to draw the grid lines behind the candlesticks?

I don't use the grids myself, but it seems pyqtgraph doesn't differentiate between the grid and the axes. Best would of course be if the axes were drawn on top of the candles, but the grid behind. I don't think there's a simple fix for that, but I recommend you change the Z value for the axes in your application.

Problem in underlying library, pyqtgraph. If desired, file a bug with them.
