I am stydying vega-lite-api (a great tool conceptually and in its incarnation) and I was wondering whether .config({ view: {width: 195, height: 190}, yXxis: {minExtent: 28} }) shouldn't instead be .config({ view: {width: 195, height: 190}, axis: {minExtent: 28} }) i.e. yXaxis --> axis If that is the case, not sure why no error was shown... Thanks for all.

Yes, this was a typo. I've removed the code, but the previously intended use was `axisY: {minExtent: 28}` which targets the y-axis only.
