Struggling to Make Graph

Question

Hello,

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.MakeGraph_management(graph_grf,graph,"Precip")
arcpy.SaveGraph_management(output_graph_name, verticalBarGraph_bmp)

Any help would be very much appreciated!!!

Hello,
I'm trying to create a script with arcpy but appears the same error message. Could you help me please?

Thanks for the response.  I would like to learn how to make these graphs through arcpy though.  I am no longer getting an error now, but I can't seem to figure out how to add input data to the graph template.  Here is my easy script for a vertical bar graph of population in various cities, in a cities point file.  When I run the script it just saves a blank vertical bar graph template, without the population data from the cities being input at all.  import arcpy
# Set local variables:
inputTemplate = "C:/reacch/graphs/VerticalBarTemplate.tee"
inputdata=arcpy.GetParameterAsText(0)
# Add a vertical bar series to the graph
graph= arcpy.Graph()
graph.addSeriesBarVertical(inputdata, "POP2000")

# Output a graph, which is created in-memory
arcpy.MakeGraph_management(inputTemplate, graph, "city_pop")
arcpy.AddMessage("here")
# Save the graph as an image
arcpy.SaveGraph_management("city_pop","C:/reacch/graphs/city_pop.jpg")

If anyone knows why the input data is not being loaded into the graph template please let me know.  Thank you in advance!

You may want to check out matplotlib, which is a python library for plotting.

http://matplotlib.sourceforge.net/gallery.html

The gallery includes code with the examples.
