I would like to create a graph (pie chart) using the attribute values in only "one" field. I have a feature class of polygons which are actually housing stocks in a settlement. The attribute table has a field indicating the type of material in the construction process (wooden, concrete, stone, etc.) I need to create a pie chart which shows the proportions of those materials in percentage, but I have just hit a dead end trying to create one. Any help would be appreciated, thank you!
P.S. The field is text and does not show up in the value field in create graph wizard. Are we not able to create graphs when we have text fields?
