Looking to be able to Pan and Zoom a Radial Tree Layout( not a Tree Layout)
I have searched Google and found "Pan and Zoom Tree in Vega"

I'm new in android and have some questions. The idea is to simulate a book page with some images and text on it and animations that zoom on a column and after clicking a button zooms on a different part of page and so on. I have seen some good libraries for imageView pinch zoom and pan like PhotoView and Subsampling image scale by davemorrissey. I want pinch zoom and pan functionality on entire constraintLayout and all its child views including textViews not just an imageView. I also have seen zoomLayout library but apparently it have some problem with constraintLayout as a child.
Is there any solution to use the lovely subsampling library for this purpose? if no, where i have to look? any suggestion will be appreciated.
thanks
After searching a bit, I found this library called "GestureViews" by alexvasilkov. it supports constraintLayout and animations!

I added to a Matlab GUI Pan and Zoom toolbars so I can move over the image presented in the axes.
After I mark a point (and adding coordinate text) and use the pan and/or zoom the marked text is shown outside the image Axes all over the GUI (it move as I pan and zoom).
The Axes, pan and zoom toolbar and the ui.figure 'Clipping' property is set to on.
There is no code as I use the toolbar and therefore how can it be solve?
Image example (White represent the outside of the Axes):
I am creating a MapBox project with a geoJson vector layer. I have been using the following example as my guide.
https://www.mapbox.com/blog/neighborhood-mapping-with-dynamic-vector-data-layers/
When I hover over any geoJson feature the stroke is changed to 2 pixels. However the stroke gets clipped by the neighboring features sometimes. I believe this has something to do with how the different features are stacked. So if I hover on a feature which is stacked near the bottom the neighboring features are covering that stroke.
Here is an example...

Is their a way to set the stroke to be inside of the polygon or a way to bring a feature to the top of the stack when hovering?
Thanks for any help!
By adding the function
layer.bringtoFront();
after setting the hover styling your polygons will come to front.
I've been using this code to display OpenCycleMap tiles on my app's mapview, but if I zoom in too far the map tiles will disappear. Since OCM tiles may not exist at close zoom levels (say, 15 or 16 for a certain area), they just don't appear when drawing the maps for a certain zoom level, and the mapview only shows the Google Street map that is underneath the OCM overlay.
Is there a way to edit the code to make the mapview display whichever map tiles are available for an area, but resized for the region that the mapview shows?
I use MKMapView.
How to show circle around annotation how in google maps ( when show current user location).
This circle moving with animation to new location and radius of circle dependent from current zoom level.
The annotations themselves don't have a property for showing a circle but you can use a circle overlay with the same center as the coordinate of the annotation to achieve this effect, just like the image below (from one of my projects).
Note: the property for the center of the circle is called "coordinate", just as for the annotations.
The second part is animating the movement. You achieve this by animating the coordinate property of the circle overlay at the same time as the coordinate property of the annotation. This way they will both move together to the new location.
This question can help you with how to move and animate the position of an annotation. If you need the radius of the circle to change at the same time (e.g. when animating the coordinate) you just use Core Animation to animate it together with the coordinate.
Concerning changing the size depending on the zoom level, Map Kit will always handle this for you automatically with Overlays and Annotations so that they always cover the same area of the map, even as the map resizes. (The second image is the same annotations and overlays as below, just zoomed in on the ones to the left (closer to Stockholm in the first image)).
