Struggling to Make Graph

I am attempting to learn how to make a graph using arcpy.  I created a vertical bar template and I am trying to make a bar graph of some precipitation data.  I keep getting an error of "<class 'arcgisscripting.ExecuteError'>: Failed to execute. Parameters are not valid.
ERROR 001020: Input series error. Incompatible parameter list.
Click 'Always reset parameters...' check-box to reset parameters.
Failed to execute (MakeGraph).

I am not even sure were this "Always reset parameters..." check-box is???

Here is a very simple code that I wrote that I can't get to work. 
# Import system modules
import arcpy
from arcpy import env
# Set environment settings
env.workspace = "c:/reacch/graphs"

# Set local variables
output_graph_name = "1910precip"
verticalBarGraph_bmp = "C:/reacch/graphs/1910precip.bmp"
graph_grf = "standard_bar.tee"
inputData = "C:/reacch/climate maps/precip1910" 
# Create the graph
graph = arcpy.Graph()

# Add a vertical bar series to the graph
graph.addSeriesBarVertical(inputData, "COUNT")

# Execute MakeGraph to create a Vertical Bar graph
arcpy.SaveGraph_management(output_graph_name, verticalBarGraph_bmp)

Any help would be very much appreciated!!!
