+Segmentation fault

+-> should not crash if input is empty (above: * is missing from lsat pattern name_ pat="lsat7_2000_*")
+
+------------------
+TODO suggestions:
+
+Scatterplot:
+- don't allow to go on when no subgroup is present:
+    - error message about missing subgroup in group <%s>
+    - fall back to group selection dialog + error message about missing
+
+- Dialog "Add scatter plot"
+   Band 1 (x axis)  <<- add
+   Band 2 (y axis)  <<- add
+
+- Scatter plot toolbar:
+  - put "Add SP" icon to the left
+  - when in "Select area" mode, un-highlight zoom + pan icons
+
+- Scatter plot window
+  - zoom icon: also allow for zoom box
+  - mouse wheel: 0.1 zoom step (not 0.5)
+  - add values to axis
+  - plot legend: strip @mapset off
+  - second plot is falling out of the main window to the left
+
+- Add class
+  - rerendering zooms out, it should not
+
+- confidence ellipse
+  - connect to "xx std dev" selection in toolbar
+  - show center of ellipse as little cross
+
+Wish:
+ - optionally link map displays for zoom/pan etc. (icon?)
