Is it a swift or objc project?

Dmitry Tumanov

@dtumanov

it started of as objc project, now 99% of code is Swift

I am trying to include it into a Swift code

is there a setting I need to flip?

Dmitry Tumanov

@dtumanov

I've even removed my bridge header and deleted the rest of the objective-c files, still the same issue

Pierre-Marc Airoldi

@petester42

I really have no idea sorry. Start a new project and add all you files again. There must be a setting but I don’t know it.

Not really related to our library though.

My project is being rejected because of bitcode enabled by apple, what do I do?

I’ve done bitecode true/false and Apple Reject my app :worried:

When I will get to work tomorrow I will print the screen for us :+1:

@MarcosJava

I was already forgetting to mention that the bitecode error in the Charts: /

Pierre-Marc Airoldi

@petester42

The error is because it has it on or off?

Marcos Felipe Souza Pinto

@MarcosJava

The both

Pierre-Marc Airoldi

@petester42

If you find out why pull requests are welcome. Seems weird though that both don’t work.

I had done thousands change in the project and this workedd ! Thanks

Pierre-Marc Airoldi

@petester42

Did the solution involve changing anything in our code or it only on your app’s side?

@danielgindi could you add @jjatie in? He's contributing a lot for swift changes. Github has introduces "projects" tab so we can manage PRs much easier, but @jjatie does not have access to add/edit them. He'd be happy to join us.

Pierre-Marc Airoldi

@petester42

It would be much easier if the repo was part of an organization

Xuan

@liuxuan30

@danielgindi please see this message

Xuan

@liuxuan30

@danielgindi please add @jjatie in ChartRealm as well :)

Move the repos to an org!

Is there a reference document for this project? I'm looking to integrate Charts into my app. However, my data values are strings and integers, and can't seem anything online that would say this is supported

James Sayer

@jsayer7_twitter

For instance, I have weather data for the next hour..My X Axis is actually a date (can be a string even, just not a double), and I have an array of precipitation probabilities (can be either string or doubles). I can't seem to get this data to display

Because it complains that the times are not doubles

Pierre-Marc Airoldi

@petester42

The key to doing something like this is that you used doubles for points on a graph but you give formatted labels to you points. For example a formatted date can be displayed as label but the actual point on the graph is an integer of time since 1970.

James Sayer

@jsayer7_twitter

Thank you Pierre-Marc! Is there a guide or tutorial anywhere for formatting this?

the only tutorials I can find online are using int based strings such as "150" and "2". Pretty simple to get the double value of that

Pierre-Marc Airoldi

@petester42

I think there might be a demo using it but I don’t know which one off the top of my head.

James Sayer

@jsayer7_twitter

`public func stringForValue(_ value: Double, axis: AxisBase?) -> String {
let date = Date(timeIntervalSince1970: value)
let components = Calendar.current.dateComponents([.hour, .minute], from: date)

    guard let hour = components.hour, let minute = components.minute else {
        return ""
    }
    let hourString = String(describing: hour)
    let minuteString = String(describing: minute)
`

Something like that?

then return a string with those two strings formatted?

Pierre-Marc Airoldi

@petester42

Ya something like that.

James Sayer

@jsayer7_twitter

Thanks, I'll see what i can do. The documentation for the formatting of the axis is not very clear

Pierre-Marc Airoldi

@petester42

If the documentation is really not clear please open an issue with suggestions of how to make it better. Or even better create a pull request updating them!

James Sayer

@jsayer7_twitter

I figured it out, I just had to wrap my head around the formatting!

Thank you Pierre for the help! I was curious if there was a way to hide the labels above a value in a line chart? I have a graph displaying the weather information for the next 60 minutes. I'm running into scenarios where the entries are so close together that the labels are overlapping

Pierre-Marc Airoldi

@petester42

Maybe if you return null for the formatting for the points you want to skip. I’m not too sure though. Maybe someone else has a better insight.

hi all - is there a way to use Charts with spm? I've tried

    dependencies: [
        .package(url: "https://github.com/danielgindi/Charts.git", from: "3.1.1")
    ],

and gotten

Dependencies: 
    https://github.com/danielgindi/Charts.git @ 3.1.1..<4.0.0
'ChartsDemo' /Users/seth/dev/swift/ChartsDemo: error: product dependency 'Charts' not found

#2950 suggests this should work.
