CorePlot with swift: there is no yAxis.majorIntervalLength

问题

Here is how my graph looks like:

I wan't the y axis to have an interval of 50 so i try doing this:

var axisSet: CPTXYAxisSet = CPTXYAxisSet(layer: graph.axisSet)
var y = axisSet.yAxis

y.majorIntervalLength = 50

But majorIntervalLength doesn't seems to exist

回答1:

Swift doesn't support NSDecimal values. We've made some changes to the Core Plot API, replacing NSDecimal with NSDecimalNumber. The changes are on the release-2.0 branch and not in a release package yet. See Core Plot issue #96 for more discussion of the issue.
