Euler.js Layout - Cytoscape - random

I have deployed this layout to my application and is working fine, but I have two questions:
"Ramdomize" parameter must be always "true" so that the browser won't run into "Memory Out of Space" error. But, my question here is how can generate the same graph orientation very time when I launch my application?
Where can I find the graph state when generated and store it as the default layout so that users can see the same graph layout with the same position every time they launch the application.
Thank you very much.
Regards,
Arthur

Xamarin forms - lottie animations

I'm a beginner with Lottie, and I have a basic question:
I have a band which provides my app information about the heart rate of the user in the BPM unit.
I had downloaded from lottiefiles.com a JSON file of heart animation which shows exactly what I want - number BPM.
My problem is that I don't know how to set dynamically values in the animation whenever I get a new BPM value from the band.
Unfortunately, I didn't found how to do so after searching on the internet.
I suspect that maybe the function animationView.SetValue can help, but I don't sure exactly how.
Any help will be appreciated!!

AutoCAD script: Find drawing position

Forgive my ignorance. I'm a web developer tasked with integrating an app with AutoCAD and I have no experience with the software or CAD files in general.
I have hooked it up to A360 and the Forge APIs and now I'm looking to modify drawings using scripts uploaded to the Design Automation API. What I need to do is add part numbers and some other data generated by the app to the drawings. I have the following script I've managed to get working which is a very basic version of what I need to achieve.
; Add a label to a drawing
-mtext 0,300 400,310 App data
Tag No: P1234567
Created: 29/09/16
; Define Attribute
-attdef
i
P1234567
tag
-
0,200
10
0
; end
This script adds an MTEXT and ATTDEF to a drawing with a bit of basic data. What I want to do is position the labels at the bottom right of the drawing.
Is it possible to get the position of the drawing from somewhere so the script can figure out where the bottom right is? Ideally it needs to work no matter where the creator has positioned the drawing.
Bonus points: I'd also like to put this data into the drawing metadata somehow, would this be beneficial and how would be the best way to achieve this?
Thanks in advance.
If you would still like to do it in Modelspace, and you can control the drawings, it is possible to achieve this by finding the position of blocks with specific names.

Can grapgviz be embeded into html page and dynamically corresponde to user's click?

I am now looking for a drawing tools which is used in my website.This tool can draw relationship diagram and can correspond to user's click.For example ,this graph shows the partnership of employees in a company , each node of the graph represents a employee. When we left click on one of the nodes of the graph , the page will show another figure,containing the details of this employee.
Some one recommend graphviz, but it seems that graphviz can only draw pre-defined picture and cannot correspond to user's input.
So , any ideas or recommendations?
You could use GraphViz to compute positions of nodes on the backend and send them back to the browser, so technically it could react to the user's input. A more natural approach would seem to me to do these computations directly in the browser, though, and I believe that's what you mean when you say react to users' input.

Android Activity.setContentView(), smooth transition?

I'm developing my first Android game and I'm having a bit of difficulty making the UI as smooth as I would like. I've spent a couple of hours googling around with no luck, I'm probably just searching for the wrong thing.
I have two different XML layout resources where each layout contains just one SurfaceView subclass. When I call activity.setContentView(R.layout.second_layout) to transition from the first layout to the second layout there is a noticeable period of time where a black screen (with a small white bar along the top) is displayed in between the two views.
I've tried various things such as; constructing the second view manually at runtime (i.e not using a layout XML file), calling activity.overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out) after activity.setContentView(R.layout.second_layout) and attempting to render to the canvas before the view has loaded (turns out the canvas is unavailable).
I don't see other games (or apps) having this issue so I presume there is a reasonably simple solution.
If you need some more information about my particular situation in order to help out then please let me know what information is missing. Any help would be largely appreciated.
Update: My answer below was written in 2010. Since then Fragments have become the norm, particularly since Fragment nesting was made possible and the support library allows this functionality to be used in a backwards compatible fashion. As such, instead of transitioning to a new Activity to perform a new "user task", you can use the one Activity and push and pop fragments within that Activity's view hierarchy. Animations can also be performed as a part of a fragment transaction (e.g. Fragment transaction animation: slide in and slide out).
This became pretty apparent not long after posting this question, however I thought I should come back here and make it clear to everyone else.
Activities are positively the way to go when developing for Android. Don't be put off by the fact that a transition may seem too minor for a separate Activity, the very foundation of Android is built around the idea of an Activity.

Any suggestions for best practices to follow when creating UI prototypes using sketchFlow for multiple screen sizes?

am looking to prototype the UI for an windows application. The app will be deployed on several display devices with different (physical) screen sizes and aspect ratios. Would like to be able to generate scenarios optimized on one display and quickly check if the layout is OK on different screen sizes, orientations. That is, I'd like to prototype one set of scenarios and "automatically" generate the same scenarios on different screens. Have superficial knowledge of MS Sketchflow. Have seen some best practices at http://www.wpftutorial.net/LayoutProperties.html#best . Am wondering if folk can advise on best practices to follow in sketchflow.
Bye
To quickly be able to check how things will look, I have 2 possible suggestions:
Use the states panel to create a state group/states that change the size of the layout container (such as layoutroot) you are working with. Then in the sketchflow player, you can select the state from the navigation menu and see how it looks.
Use a ChangePropertyAction behavior from the asset panel attached to a button. You can set the height or width to the size you want. If you use 2, you can set both the height and width. This would give you the ability to control the layout size and see how it is rendered.
Hope that helps, let me know if you need more info.
Keep a consistent theme between the pages, kind of goes without saying.
