SwiftUI Chart scale issue

Hey guys I'm playing around with swiftUI charts using data from Yahoo Finance public api. I'm getting a data set of charts data and trying to display it using SwiftUI charts.

My chart seems broken compared to what I'm seeing on the Yahoo webpage:

My code looks like this (tried to keep it super simple for the example):

    VStack {
      Chart {
        ForEach(viewmodel.chartData1) { chartData in
          LineMark(x: .value("date", chartData.date),
               y: .value("amount", "\(chartData.high)"))
          .interpolationMethod(.catmullRom)
           
           
        }
      }
    }
    .task { await viewmodel.getSymbols() }
  }

So I'm not sure what I'm doing wrong and why does my chart looks downward trending like that. Any help, any lead would help!
