well, have you installed the expense manager - content statistics plugin as well?

Yes i have installed the Expense Manager plugin. I can get all charts works for statistics ranking but the evolution in time i cannot. I have read the tutorial but still cannot add other data. For example say i have the following expense categories, gas, rent, food and other. How can i show all four of these on the graph for the last 12 months?

well, you would create a "COMPARE" evoltuion in time graphic, and then in each data set you would set the option "specific category", and then assign the category ID (like.. 1, 2, 6, whatever it is)

Can you tell me how to do this? And I see no information anywhere where I can see the category ID#, what am I missing? I am using joomla 2.5

yes, look at the screenshot. you need to select "specific cateogry" in the selector field, and then in the specific ID filter, you set the category ID that you want to display (ID number 2, in this example)

right, but how can i find the category ID?????

hello,

you can find it for example if you filter the items in Expense Manager by a category, in the URL you will see the &category_id= variable and you can see the ID (the number)
