I am trying to make a chart that looks like: Basically a couple overlapping range AreaMark's, a LineMark and a couple RuleMarks. However when I have two separate AreaMark's I get this: When one or the other of the AreaMark's ForEach loop is commented out it displays the proper graph. Its just the overlap of the two that is wonky. FYI - The top graph was generated by the SwiftUI Charts package on GitHub which we are trying to move away from. Thanks.
