Day 11 of #24daysofqgis: Never accept the default dark black outlines used when loading polygon layers into a GIS. Instead, match them with the interior color of the fill and then tweak for a much more refined appearance! #qgis #dataviz #cartographypic.twitter.com/1N95DE4vpD

Day 20 of
#24daysofqgis: Want to lock a layout map item at a particular scale? Paste the scale value into the "data defined scale" widget and it will remain fixed, regardless of how you resize your map! (this trick also works for extent values!)#qgis#dataviz#cartographypic.twitter.com/NZdqnGr1jlPrikaži ovu nit -

Day 21 of
#24daysofqgis by@nirvn: "the is_layer_visible() expression function can be used to dynamically change label color based on the visibility of base layers -- your maps can intelligently adapt and automatically improve their own readability!"#qgis#dataviz#cartographypic.twitter.com/NF92a9OFbwPrikaži ovu nit -
Days 22 & 23 of
#24daysofqgis (pt 1) - Expression variables provide a mechanism for influencing the map rendering of symbols and labels on a layout-by-layout (or layout map-by-layout map basis). Eg. use the strpos function along with a custom variable to filter a layer...pic.twitter.com/46h2TlqYjXPrikaži ovu nit -

#24daysofqgis (pt 2) ... and then set this variable to specific comma separated lists of the desired features for each individual layout map, to give per-map filtering without messing with multiple layer copies!#qgis#dataviz#cartographypic.twitter.com/daEEheY8x2Prikaži ovu nit -
Day 24 of
#24daysofqgis: You can greatly improve the appearance of maps by simplifying data to a level appropriate to the desired map scale. Use the grass v.generalize algorithm from#qgis, or hit up the fantastic mapshaper website (https://mapshaper.org/ )!#dataviz#cartographypic.twitter.com/6zXEXmHYJSPrikaži ovu nit -
