davaxi/sparkline is set to the version
This results in the following error when running
composer require piwik/piwik
Problem 1 - piwik/piwik 3.13.1 requires davaxi/sparkline dev-multiple-series -> no matching package found.
@diosmosis should know best about it but I have no idea why this fails. While we should now be using the latest upstream (#15465), the branch still exists and should therefore work in composer (https://github.com/matomo-org/Sparkline/tree/multiple-series)
Maybe caused by a composer setting? I'm not sure why this would fail.
I can reproduce the issue. Not sure why it doesn't work though or how it needs to be configured etc. It looks like we used to use 1.1 so we could change it to 1.2 or so?
I've created PRs to update that, but actually the latest release has
another bug, that produces warnings on PHP 5 and an error on PHP 7. Created
a PR to fix it in the lib. Hope it gets merged soon and a new version is
released, so we can update it...
@sgiehl looks like a new release maybe coming next week https://github.com/davaxi/Sparkline/pull/15#issuecomment-580148795
