change BarGraphItem axis labels

[Pietro]

Hi,

I would like to make a BarGraphItem plot using text label as ticks for the axis of the graph instead of numbers. but I didn’t understand how can I set my labels.
I saw the AxisItem class, so I can inherit from this class, overwrite the tickStrings method, create an instance but then I don’t understand how/where I can say at the BarGraphItem must use my instance instead of the default one.

Any hint?

No need to inherit, just use AxisItem.setTicks: 

http://pyqtgraph.org/documentation/graphicsItems/axisitem.html#pyqtgraph.AxisItem.setTicks

Example:

    plot.getAxis('bottom').setTicks([[(1, 'one'), (2, 'two')]])

Hi,
  I am using this to set the tick strings for the left axis. My strings are long and they get cropped. How do I move the axis position (manually or automatically), so that all the ticks are completely visible?

It's a bug! 

I have just pushed a fix to the develop branch on github. If you want to stay with 0.9.8 for now, then you can use AxisItem.setWidth() to manually expand the text space.

Thanks for the report.

Thanks! I can confirm that the bugfix works for me.
