Hi,
To answer the second point, something like
self.myplot.getAxis("top").setStyle(tickLength=0, showValues=False)
will draw just a plain line as an axis.
I knew you were going to ask the first point... :) Unfortunately there is
just one "pen" parameter to AxisItem
<http://www.pyqtgraph.org/documentation/graphicsItems/axisitem.html#pyqtgraph.AxisItem.setPen>
which controls the color of the axis line, grid lines and labels. So this
probably doesn't do what you want:
self.myplot.getAxis("bottom").setPen({"color": (255, 0, 0), "width": 5})
I can't see an easy way to change this. The easiest would be to do it by
subclassing AxisItem, and just overriding the drawPicture
<http://www.pyqtgraph.org/documentation/_modules/pyqtgraph/graphicsItems/AxisItem.html#AxisItem>
method with different hardcoded pens for axis lines, and grid lines. A
nicer way would be to put the options in the constructor of course... When
you create a PlotItem
<http://www.pyqtgraph.org/documentation/graphicsItems/plotitem.html#pyqtgraph.PlotItem.__init__>
(eg with graphicsLayout.addPlot(...) method, you can pass in instances of
your custom AxisItem(s) you have created for it to use.
