+B<[--no-gridfit]>
+
+To avoid antialiasing effects gridlines are placed on 
+integer pixel values. This is by default done by extending 
+the scale so gridlines happends to be spaced using an 
+integer number of pixels, and starts on integer pixel value.
+This might extend the scale too much for some logarithmic scales
+and for linear scales where --alt-autoscale is needed.
+Using --no-gridfit disables modification of the scale,
+and just truncates y-coordinates to integer values for bitmap
+formats.
