These aren't the most polished extensions, but they display some information in a way that you can't readily see otherwise.

The Cash Flow Chart extension's primary use, tracking overall expense/income trends, can be accomplished now that the Net Worth graph in Moneydance 2010 lets you select which accounts to use. This extension still allows for some additional details (breaking that info out by account on the same graph) so I'm leaving it up here, but if you think this extension solves a problem for you, you might want to check out MD2010 and the Net Worth graph's options.

This page contains some extensions for Moneydance personal financial software.

Extension	Description	Source link	Download	Help	Screenshot
Cash Flow Chart	Shows income, expense, and optionally net values for a user-selected group of accounts over a user-set period of time, displayed in months. Useful to see whether you're spending more money than you're making, and look for trends.	tarball code	cashflow.mxt (1.8MB)	Settings
Daily Balance	Lists the balance each day for the next 30 days of all the top-level accounts	tarball code	dailybal.mxt (10KB)	(no options)
Income + Expenses / month	Lists incomes and expenses per month, per account. Requires the Python Interface extension: load this script with that extension's "read from file" dialog.	incexpmo.py	(no binary)	Instructions

Here is my public key, to verify the signatures on the extensions: pub_key. Although I don't know how to use this to verify the file is okay, so I am not sure how much this will help you.

In writing these extensions, I leaned pretty heavily on:

• The sample extension from the Moneydance Developer's Kit
• The sample Python scripts from the right sidebar of the Moneydance developer page, coupled with the Python Interface extension, to understand how to use the Moneydance API
• The Portfolio Allocation extension at http://code.google.com/p/moneydance-portfolioallocation/ to understand how to use the JFreeCharts API

If you're looking to write your own extension from scratch I'd start with those sources, rather than these extensions which are pretty poorly written.

Also, a word of warning on extensions: if you load an extension into Moneydance, the extension will have full access to all your data, including the ability to change your data, delete it, or upload it onto the Internet. I strongly recommend that you examine the source code to these extensions yourself, verify there's nothing harmful, and then compile the extension yourself, rather than downloading and running a pre-compiled extension.
