hledger-web graph weirdness/bug

[Marko Kocić]

Hi Simon,

When starting to actually use multiple currencies, I found that that nice and useful graph on hledge-web started to look weird. Take this[1] hledger that demonstrates the problem.

The graph looks fine and well until first $ transaction. Then, It starts to display 300 as a value in graph, regardless of other transactions after that.
To be honest, I don't know what would be the best way to graph when having multiple currencies in an account.
- One way would be to have multiple lines in graph (one per currency).
- Another one would be to calculate and display totals based on current exchange rate extracted from transactions.
- Leave it as is, and suggest a workaround for dealing with multiple currencies.
In general, I am open to hear how are people using multiple currencies in hledger, especially in hledger-web context.

Best regards,
Marko Kocić

Hi Marko,

one line per currency would be awesome. Let's have that. :)

I'm not actually seeing the problem you describe. I pasted your data into t.j, adding a second space before "-250". What account/url are you looking at ? I see e.g. the attached.

me too.

Sorry, my bad.
The following transactions demonstrates it better. Here, when you look at assets:paypal, the graph shows a flat line after first $ income, since somehow graph switches from dispalying only € to displaying only $.
