Tutorial does not consider auto-layout about swiftcharts HOT 12 CLOSED

Thanks. For what exactly do you want to use auto layout?

If it's for the chart's view, you can pass a view to the initializer instead of a frame. The view can come from a storyboard or a xib. You can use auto layout normally.

Note that you have to set the view's class to ChartBaseView (in the identity inspector).

from swiftcharts.

I added UIView in the storyboard setting class as ChartBaseView
@IBOutlet weak var viewArea: ChartBaseView!
Then
let chartFrame = viewArea.bounds
Finally
viewArea.addSubview(chart.view)

But it does not work, which method should I use? Thanks

from swiftcharts.

You have to pass viewArea to the chart:

let chart = Chart(
    view: viewArea,
    layers: [...]
)

And since viewArea is already in your view hierarchy, you don't have to add it again. chart.view is viewArea.

I did that but I stop seeing axes and grid.
Possible?

from swiftcharts.

You are probably using the view before its frame is calculated. When you use auto layout this doesn't happen immediately. Try putting the chart initialization in viewDidLayoutSubviews. You will need a flag to check if it ran already because it's called multiple times. Here is a gist: https://gist.github.com/i-schuetz/f6e285eb0c86bb831510

Alternatively you can use viewDidAppear, which is called only once, but this happens a bit too late in the display process and there will be a noticeable delay.

You closed this, but the question has not been solved!

from swiftcharts.

Since you stopped answering and opened a new issue where you recently implied that you see axis values (which solves your last comment) I assumed this was solved. What is missing?

from swiftcharts.

I solved the axis problem. But the auto layout has not been solved. As I've already replayed to your other link. Your tutorial about autolayout does not work properly. The image is stretched and not proportionally rotated.

Which image? Rotation? Can you post a full example / description, maybe also a screenshot so I can get an idea of the problem?

Ok, the code was missing handling of rotation change. You didn't mention that you need this. I updated it. Now it resizes correctly. Note that you have the possibility to use different interval sizes depending of the orientation (in case you would for example want to show more x values, because there is more screen space available).

from swiftcharts.

Could be interesting to activate scroll on the xAxis only when landscape view is activated. I'll try to figure out on my own, in case I'll open a new question :)
