legendprint-composerqgis
I'm a new QGIS user, still finding my way around. I've created a map and am now preparing for export in print composer.
I've added a legend with ten items, and I want the items to break across five columns evenly. I've specified the number of columns and checked Split Layers, but the end result is three columns of two items, one column of three items, and a final column of one item:
How can I correct this to display evenly?
I'm reasonably certain there's not a good way to do this. Here's a terrible, terrible workaround.
Cover the legend text that you want italicized with a label with the same text in italics. Select the legend and the label and Group Items so you don't accidentally move one without the other.
Ta DA!
Sadly, this isn't a joke. I used to do this a lot. Then I decided to just live with un-italicized botanical names, and hope that my former Plant Systematics professor never sees one of my maps. At least the genus is capitalized and the specific epithet is lower case.
Try the code snippet below:
map_layer = QgsProject.instance().mapLayersByName('Soil cover')[0]
manager = QgsProject.instance().layoutManager()
layout = manager.layoutByName("Test Layout")
legend = layout.itemById("legend")
layer_node = legend.model().rootGroup().findLayer(map_layer)
legend.setAutoUpdateModel(True)
layer_node.setLabelExpression('wordwrap(@symbol_label, 30)')
layout.refresh()
You can see the results on my test layer and layout below (I used the expression 'wordwrap(@symbol_label, 10)')

Not completely sure why but for 10 legend items, increasing the column count to 6 instead of 5 seems to split the items equally.
Perhaps it is related to hiding the group/subgroup name which seems to count as a legend item itself...
