altair.Chart() which outputs fine if I render it directly but if I wrap it in a mo.ui.altair_chart() then the string x-axis values which are versions of the form "x.y.x" are getting evaluated as datetimes so the graph is exactly the same except the x-values are erroneously shown as datetimes. How can I stop this? See https://imgur.com/a/0wFfaYk. First graph is raw altair graph, second is wrapped graph.
