Hi, I want to customize grid lines, as in:
1. using specific pens to allow customization of grid line color, thickness, and style, independent of the corresponding axis object 2. notion of major / minor gridlines 3. separate control over horizontal / vertical grid lines As these specifications are not available in pyqtgraph by default, I'd like to understand the best way to implement this. My current understanding is that I need to subclass GridItem, and re-implement GridItem.generatePicture(self). Even for Spec 1, I don't see a simple way to do this. Following Luke's suggestion (see here <http://stackoverflow.com/questions/17784547/how-to-apply-pyqtgraph-mkpen-to-a-griditem>) of subclassing GridItem and creating a setPen() method also requires rewriting the generatePicture() to replace the hard-coded pens with the customized ones. Furthermore, the drawing algorithm in GridItem.generatePicture() makes it difficult to implement spec 2 or 3. Before I implement such a change, I want to ensure that I am looking at the right method to modify. Am I right that re-implementing GridItem.generatePicture() is the way forward? regards, Nick -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
