I created a point shapefile in QGIS 2.01. Then, I changed the style of the points so they display the contents of the Acceleration field in the attribute table. Works exactly as I require.
Now I would like to apply the same style to a second field in the table, but when I select that field in the Style dialog box, all the symbols are reset to their original display characteristics (colour, size). Is there a way to retain the current style definitions, and simply apply them to a second field? The value ranges are identical for both fields, so the same symbology could apply.
I tried to save the style using the Save Style button. Tried both options (*.qml and *.sld), but neither of them created a file. The *.sld option generated an error message that I should check the folder permissions, but that does not make sense because I've been using that folder to store the shapefiles.
