When switching the chart type from Columns to Heat Map, the Height field changes to Value. Visualizing negative, null, and zero values GeoFlow supports visualizing negative, null, and zero values. The following visualization can be created for this simple table: City Value Date Seattle 3 1/2/2009 Portland -7 1/5/2009 Tacoma -2 1/5/2010 Seattle 3 1/2/2010 Portland 4 1/5/2011 Tacoma 5 1/5/2011 Edmonds 0 1/5/2011 You can see the zero value for Edmonds, WA as a hollow square next to the taller column which is Seattle. You can see the negative value -7 for Portland, OR on 1/5/2009 as a visual which is shown below the surface in this screen shot. NOTE: Zero values and Null values are visualized in the same way. You can turn on null, zero and negative values in the Layer Manager settings task pane.
