<p class="MsoNormal">I’m using qgis 1.8 to create graduated maps of multiple data columns. For this, I use the new symbology implementation, with graduated colors. I would like to use one classification for all columns. Usually based on Jenks, and tweaked manually.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In qgis 1.8, when changing the column which is used for the classification, the classification is recomputed automatically. This is inconvenient, because now I have to enter the ranges for the classification for each map I want to make.
I expected the classification to only be recomputed when I press the button ‘Classify’.<o:p></o:p></p>
<p class="MsoNormal"><br>
The workaround I have found is to create my classification, then switch to old symbology, which retains the classifcation when I change the column.<o:p></o:p></p>
<p class="MsoNormal"><br>
Is this a bug or a feature? And if it’s a feature, how can I switch it offf?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your reply.<o:p></o:p></p>
