Board Game Charts gather publicly available data from BoardGameGeek™ (Collection, Plays), but you can also upload your private data to get access to more and better detailed charts.
It is also recommended that you change your settings to get more accurate charts. If you input a monthly budget, many of the spending dashboard's charts will include your budget.
If you insert data of your trades (see Trades) your monthly budget will be increased by the amount of money you gained in the trade.
If you have suggestions or want more information, check out the guild on BGG.
Board Game Charts can list all your trades, as long as you insert all the required data:
Example: 11th Jan 2017, you traded Agricola & The Capitals for Cosmic Encounter & $24
Mark Agricola as previously owned, then add the custom private comment [SoldFor 24][SoldDate 2017-01-11]
Mark The Capitals as previously owned, then add the custom private comment [SoldFor 0][SoldDate 2017-01-11]
Mark Cosmic Encounter as owned, then add the private info Acquisition Date: 2017-01-11 and the custom private comment [AcquisitionType Trade].
You can group plays by adding tags into the comment field of logged plays. Tags are made by using square brackets and custom text (i.e., [text]).
Example: You've played Aeon's End and want to mark that you played against the Gate Witch. By writing [Gate Witch] into the comment field you'll be able to see all your stats for that specific tag.
You can also add multiple tags to a specific play to get that play included in different tags.
Example: You've played Runebound, a game that can be played competitively or cooperatively, and want to mark that you played aganist The Red Death, a cooperative scenario. By adding [The Red Death][CoOp] you'll be able to see the specific scenarios stats, but you'll also get all the stats for all coop scenarios.
To accurately get information about collection sizes etc, you can add information about when you received the game (and not only paid for it) by using the [ReceivedDate] tag. However acquisiton date is used instead of received date if no received date is given.
To add a received date, simply add [ReceivedDate 2018-02-12] text to the private custom comment field.
Example: You've ordered a game on 2017-12-02, but received the game on 2018-02-12. In this case you should add 2017-12-02 to the normal acquisition date field, but add the [ReceivedDate 2018-02-12] tag to the custom private comment field.
You can add the number of sleeves you have used for a game/expansion to get a more accurate price of your collection. The cost of the sleeves will be calculated at the acquisition date of the game.
To add the number of sleeves, simply add [Sleeves X] text to the private custom comment field, where X is the amount of sleeves used. You will also need to go to the settings page and insert a cost per sleeve.
Example: You've used 250 sleeves for a game. In this case you should add the [Sleeves 250] tag to the custom private comment field.
