screenshots to show issue

SUMMARY
When using a credit card account, the ledger view "Show balance chart" plot
account balance limit line appears to be at odds with the account balance plot.

I will attach a pdf with some screenshots.

STEPS TO REPRODUCE
1. Create a credit card account
2. Specify a credit limit for the account
3. Create some credit card transactions
4. In the ledger view for the credit card account press "Show balance chart"

OBSERVED RESULT
The account balance (when you have debit) is plotted as a positive number.
The account balance limit is plotted as a negative number. 

EXPECTED RESULT
I was expecting the account balance limit to be plotted as a positive number,
and not a negative number.
However, on reflection I guess an alternative view is that the account balance
(when you have debit) should be plotted as a negative number.

What seems incorrect is that the account balance and the account balance limit
numbers appear to be plotted with different "polarities".
