Marker frame adjustment according to bounds

[kaustubhkabra]

I am showing values on a standard graph, which has minimum origin defined. The Chartview is added as a subview on UISplitViewController. As a result, the marker view which appears on click of a point close to X axis is getting cut. Screenshot-

Any suggestion to fix this behaviour ?

have you tried find out which view is responsible for clipping, the chart view, or your super view?

[kaustubhkabra]

I want the marker view to be on top of any underlying subviews. Still better, if it can sense the bounds of chart view and align content/arrow location such that no clipping happens - similar to way iOS presents UIPopupViewController.

Thanks for the quick reply !

I checked that drawMarkers(context: context!) will not be clipped, it's not another view. Do you set any maskToBounds in your super views?

[kaustubhkabra]

Nothing explicitly set for maskToBounds to any views in this controller.

[liuxuan30]

Well I guess you need to debug then. Just walk through you super views and see who's frame your marker view got clipped out of the frame.

[liuxuan30]

BTW, you need to check how you draw the text as well.

[kaustubhkabra]

ok thanks, will check and update this thread later.

As per your suggestion, I tried setting masksToBounds and clipsToBounds to NO for all superviews in hierarchy of chart view.

UIView *thisView = self.chartView; //this is reference to my line chart view
do{
thisView.clipsToBounds = NO;
thisView.layer.masksToBounds = NO;
thisView = v.superview;
} while(thisView != nil);

Issue still persists. Any insights ?

If no view clips your marker, have you checked how you draw the text. I looked at your screenshot, the text is first not left aligned? You may check here too. You could try use another background color to exclude what's the root cause. If your marker view is not clipped at all, then it's text drawing issue, like font size, multiple lines, alignment, etc.

@kaustubh-kabra any updates?

@KK-CODE how do you set values to Marker View before showing them on click of chart?

I have the similar question. How do you show maker and highlights bar on a first lunch instead of touch?
