I think it would be nice to preserve the behavior today where you get the first axis with e.g. `chart.value_axis` and only expose the multiple axes via some new API like `chart.value_axes_list`.\n\nThere will need to be provisions for working with axis IDs and assigning the axis IDs for each plot within a chart.  The `pptx.chart.axis._BaseAxis` will need to be able to set `c:crossAx`, `c:crosses`, and `c:axPos` values.\n"},"comment":{"url":"https://api.github.com/repos/scanny/python-pptx/issues/comments/262902772","html_url":"https://github.com/scanny/python-pptx/issues/141#issuecomment-262902772","issue_url":"https://api.github.com/repos/scanny/python-pptx/issues/141","id":262902772,"user":{"login":"zkn365","id":863497,"avatar_url":"https://avatars.githubusercontent.com/u/863497?v=3","gravatar_id":"","url":"https://api.github.com/users/zkn365","html_url":"https://github.com/zkn365","followers_url":"https://api.github.com/users/zkn365/followers","following_url":"https://api.github.com/users/zkn365/following{/other_user}","gists_url":"https://api.github.com/users/zkn365/gists{/gist_id}","starred_url":"https://api.github.com/users/zkn365/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/zkn365/subscriptions","organizations_url":"https://api.github.com/users/zkn365/orgs","repos_url":"https://api.github.com/users/zkn365/repos","events_url":"https://api.github.com/users/zkn365/events{/privacy}","received_events_url":"https://api.github.com/users/zkn365/received_events","type":"User","site_admin":false},"created_at":"2016-11-25T08:18:52Z","updated_at":"2016-11-25T08:18:52Z","body":"Is the API for the second y axis avaiable now?
