The title of this pull-request should be a brief description of what the pull-request fixes/improves/changes. Ideally 50 characters or less.


GitHub issue(s):

#130

What does this Pull Request do?

  • Add a scaling feature to enable showing of more labels on graph.
  • Make the transition from page to full screen more consistent (same graph shows in each place).
  • Move default settings to instance rather than library.

How should this be tested?

Spin up an instance with an account and use the "scale up" feature. What should happen is that the next-to-largest nodes will get larger and therefore start to show labels.
Switching back-and-forth from fullscreen should show the exact same graph.

Additional Notes:

The scale up checks whether each node is the same size as the largest node and if not, it squares the size value. Sigma takes care of the scaling and displaying.

I tried "scale down" using sqrt, but the max-value check means scale down does not restore back from scale up. I found that confusing, so just left "scale up" which can be restored to normal using refresh.

I'm sure there's a font-awesome icon for this feature instead of text, but I did not see it yet. Icon options for bootstrap 4 are here: https://fontawesome.bootstrapcheatsheets.com/

I got an eslint error for sorttable on run, but did not know how to fix that, so I left it for now.

.fa-level-up and fa-level-down make sense to me. Can you add tooltips or hover text to those buttons?

I'm not too comfortable merging this with only having a scale-up, and not the opposite. Can you do some more research there to figure out a solution?

I'll give it a shot. The main issue is the stop-gap, which is necessary to avoid Inf values. Take for example, the case where the biggest node is size 100,000 and I scale up until (say) 10 values have size 100,000. When I scale down again, the values that are 100,000 will be treated as the same, when originally they were not.

For the network I was working with, I did not see very much value in the scale down. It basically did the same thing, except it sized the smaller nodes more quickly. This could be different for graphs of larger size I imagine, but I'm not sure.

Maybe instead of "scale up" we could use "spline." Another option is to give up on this all together as a neat idea, but not really that helpful in the end.

Realized that I could try to make this happen using some form of state-like object like with ReactJS or a C struct so that "scale down" reverts to a previous state. Might be more trouble than it's worth though.

Agreed on scale-down - it would be nice to have, just in case somebody is clicking too fast and wants to go back.

A question. Here's a step in the 'scale-up,' where we lose the original label in favour of another one. What's going on here?

Step One:

Step Two:

Note that fmap.com disappears after clicking "scale up" despite being the most significant node earlier.

I think it's worth trying to get this implemented FWIW – you're pretty close and have a few ideas of how to potentially resolve this problem.

Okay - if it's worth trying, then I'm willing to put in the time using some kind of state management. That'll take a bit of time to get set up.

The reason why fmap got lost probably has to do with the fact that the other values overtook the max value when they were squared and then became the max value. I thought I plugged that bug up, but it looks like I didn't.

Great, thanks Ryan – that sounds like a good approach to me.

To my astonishment, both scale up and scale down now work!
Applied natural log & exp logic instead of previous.

For reference, the current format uses natural log transform or the current value if conducting the transform results in a non-finite value. Scale down uses x^e or the current value if the x^e is a non-finite value.

Instead of "request changes" this should be "consider changes." ;)

var nodes = instance.graph.nodes();
var max = Math.max(...nodes.map(x => x.size));
nodes.forEach(x => {
if (isFinite(Math.log(x.size + 1))) {

I found the scaling up and down a bit too gradual - it was hard to notice anything was happening.

Changing the x.size +1 etc. values to + 2 makes it a more vivid change, and I think is still granular enough to be useful. But I'm also happy to be convinced about using +1. 😄

What's the status of hover text on the buttons?

I'm still noticing @ianmilligan1's issue with fmap appearing disappearing at different points of scale-up/down.

Going to try rounding to resolve the fmap error.

commented Jun 6, 2018

Okay - rounding just made it worse. There's just no getting around the floating point problems here unfortunately. Here are the options for this:

  1. Accept the scaling as is with clear tooltips that they are simply transforms of the data (either x^e or nl(x)). There will be only very limited consistency for the up and downs.
  2. Have only one form of scaling and a revert.
  3. Leave this option out.

The state management option is overkill for this feature and could cause even worse problems down the road. There's no guarantee that managing state will scale for larger graphs either.

Let's have a think.. are there any collections that would benefit from a scale down out of the box, or will users be generally scaling up the collection.

My vote would be for either one or two, and I see pros and cons for both. Having both is very good, but we'd have to be very clear about what it's doing and some of the downsides. But if people are mostly scaling up and then hitting down to just sort of serve as an undo, that might be ok.

Having just scale up probably covers most but not all of the use cases, but it seems a bit unbalanced to have an up and not a down.

Yes. Let's have a sit on this for a week. It seems like I could be mistaken about the reversion, but I have to see why it's acting so wonky. The biggest problem is if people scale down super far and then scale up. Scaling up and then scaling down is not a problem. I could just do a scale up and once scaled, add the scale down button until it's back to normal and then remove the button?

Thats' a very tempting option (or maybe have the scale down button greyed out or visibly inactive).

Giving the user the ability to upscale the nodes is helpful. I would argue to being able to undo this is useful as well after upscaling, as it allows for examining the visualization at a glance without the visual "loudness" of large but easily clickable nodes.

Also, I would recommend not adding new UI elements after a condition occurs. Make it present but greyed until it is activated by the user hitting the upscale button.

OK. I think with discussion, @greebie, why don't you implement the scale up button (I'd recommend with a step of +2) and grey the scale down button out until a scale up (and similarly grey it back out when the user has brought it back to the starting point too).

Sound good?

Yes, I intend to implement the changes. I think I need the weekend to figure out how to manage state changes without overcomplicating things.

Add disabled to scale-down button.
Set state management for up and down.

I think I have this fixed now. I established a basic increment/decrement state apparatus here. If we start wanting more, I suggest we move to Redux or a more comprehensive state management library.

Just based on exploring with with @SamFritz yesterday - the tooltips popped out at me.

<span class="fa fa-level-up"></span>
</button>
<button type="button" id="modal-scale-down" class="scale-down" data-toggle="tooltip" title="Transform node sizes using log transform." disabled>
<span class="fa fa-level-down"></span>

Was looking at these with @SamFritz yesterday.

"Transform node sizes by the power of e." is probably not going to mean much to a lay user. Is it possible to just use more straightforward language ("increase node size") and ("decrease node size") and then maybe connect with Sam and give her some suggested language to describe these in the AUK docs?

<span class="fa fa-refresh"></span>
</button>
<button type="button" id="scale-up" class="scale-up" data-toggle="tooltip" data-placement="top" title="Transform node sizes by the power of e.">
<span class="fa fa-level-up"></span>
