SwiftUI Bar Chart

I have implement that chart, however, when I switch to another tabview and return back, the config setting get ignores or sometimes doesn't show the data at all. Here is my code:

`var body:some View { let drag = DragGesture() .onChanged({ self.offset = $0.translation }) .onEnded({ if $0.translation.width < -50 { self.offset = .init(width:-1000, height: 0) dragDirection = .left } else if $0.translation.width > 50 { self.offset = .init(width: 1000, height: 0) dragDirection = .right } else { self.offset = .zero } }) ZStack {

        Text("No Data Available...").opacity(self.entries.isEmpty ? 1.0:0.0)
        VStack(alignment: .leading, spacing: 0) {
            
            self.selectionIndicatorView()
            
            SelectableBarChartView<SelectionLine>(config: self.config)
            .onBarSelection { entry, location in
                self.selectedBarTopCentreLocation = location
                self.selectedEntry = entry
            }
            .selectionView {
                SelectionLine(location: self.selectedBarTopCentreLocation,
                              height: 150)
            }
            .onAppear() {

                
                HealthKitData.instance.configDataEntities(index, dragDirection, endDate: endDate, dataType: .chartData, requestedData: requestedData, completionChartData: { (data,total,begin,end,endDate) in
                    self.entries = data
                    self.config.data.entries = data
                    configChartSettings()
                    self.totalSteps = total
                    self.beginTime = begin
                    self.endTime = end
                    self.endDate = endDate
                    
                }, completionComponentData: {_ in })
                
            }
                .animation(.easeInOut)
            .onDisappear() {
                tempIndex = .Day
                index = .Day
                endDate = Date()
                dragDirection = .nothing
                self.hasAppeared = true
            }
            
              
                .onReceive([index].publisher.last(), perform: { value in
                    
                    if value != tempIndex {

I have run this project in Xcode 12 and It through below error in Swift UI.

SelectableBarChartExample-iOS[31888:477881] [SwiftUI] Invalid frame dimension (negative or non-finite).

Release 1.3.2 had a breaking interface change which causes problems for teams that use SPM 'next major' versioning. This API change was also not denoted in the release notes. Not a huge deal, my team was able to update our code. That having been said, SPM works really well when Semantic Versioning is followed as recommended by Apple.

Very handy library, I hope to see new releases take this into consideration.

The property dash on AxisBase.swift was refactored/reworked to style.

Hi, I am working on a project that utilizes your amazing Barchart system. I encountered a situation I am hoping the community can assist me on.

I have a a list of two Months, February to March.
For Data we have 31 days.
I have values on February 14, and March 14. If I have just the days stored. 1-13, There's no way to know if it's March 14 or February 14. The Indices for XAxis Listed are "14, 21, 28, 7, 14". As you can see, you can not tell what month it us. When I select, March 14, The system only see's 14, and will pick Feb 14, not March 14. I changed the Indice tobe: "Feb 14, Feb 21, Feb 28, Mar 7, Mar 14" For the labels under chart. Unformately my team wants just number. While this works but the team want the labels to behave as before.

Does anyone have ideas of what I can do in this framework? I looked for properties I can access but nothing public can be used without causing other unwanted behavior. I am hoping someone more familiar with the framework can offer suggestions. Thank you in advance for those are able to help.

Hey Guys, love your work. Do you happen to have an ETA on that feature? "[WIP] horizontal scrolling" Thats the only feature missing for it to be an amazing lib :)

Thanks in advance

I'm using your library however it gives an error in ChartConfiguration.swift file.

Publishing changes from background threads is not allowed; make sure to publish values from the main thread (via operators like receive(on:)) on model updates.

Hi,

first of all thanks for the great library.

Would it be possibly to set a max label value on the YAxis?

What I am trying to achieve is the following:

The highest possible value that can be displayed in my chart is 17. Therefore I would only like to show YAxis-label and lines until 15. At the moment, however the chart automatically draws a label / line at 20.
