Scattergl lasso #1657

dy · 2017-05-09T19:23:20Z

Enables svg interactions for scattergl plot.
Some minor issues TODO:

zooming loses selection
autoscale loses cdata.plot
~~opacity of huge number of points is indistinguishable from non-selected points~~
blinking of some points on selection
picking is lost
fix tests
low fps on selection (ok at 1e5)
~~panning does not clear selection~~
add tests

This will be useful for the crossfilter project too, where large D3 line and scatter plots may not be zippy enough: #1316

jackparmer · 2017-05-16T20:11:34Z

Hey @dfcreative will scattergl have plotly_selected and plotly_deselect events identical to its SVG counterpart?

First pass comments.

This is looking promising. Nice job @dfcreative

Looks like you broke the gl2d hover spikes (i.e. those black lines to go from data point down to the axes).

I think for this iteration we should keep the current gl2d hover routine (the mouseContainer thing in scene2d.js) and add just what we need from Cartesian for selections.

I'd prefer

.plot might not be best here. This is really a trace module though .trace is already taken.

Maybe .glTrace?

Smart 👍

Now, can you rm src/trace/scattergl/calc.js?

... but that might slow down scattergl for 1e5+ point graphs. 😕

For the record, we must make sure plotting 1e6 points with scattergl (passing through updateFast) clocks in at around 1 second.

That is required to obtain selection in scattergl/select. Mb it is possible to optimize that, just haven't got that a chance.

Actually I see no speed difference compared to old implementation for 1e6.

@etpinard ~3300ms vs ~3500ms for 1e6 points, that is 200ms slowdown due to

var x = xa.makeCalcdata(trace, 'x'), y = ya.makeCalcdata(trace, 'y');

That's ~3300ms on master?

@etpinard just updated master and plugged laptop: ~3000ms vs ~3200ms, I hardly notice the difference due to fluctuations

Wow. That's brutal. Does anyone else have to wait 3000ms when plotting 1e6 points?

With 6ac722d we're back in the ~1500ms for 1e6 first render as on master 🎉

Most of scattergl/calc.js is now skipped when dragmode is set to pan/zoom (the default).

Calling Plotly.relayout from pan/zoom to lasso/select now trigger a recalc where gd.calcdata is filled so that the selection logic knows what to do.

+        subplots = [plotinfo].concat((ns && ew && plotinfo.overlays) ? plotinfo.overlays : []);


Why do we need the extra && plotinfo.overlays now?

... e.g all of these are useless in gl2d

    if(!this.staticPlot) this.container.removeChild(this.canvas);
    this.container.removeChild(this.svgContainer);
-    this.container.removeChild(this.mouseContainer);


Hmm. That probably breaks gl2d/camera.js

So wait, are we 🔪 the gl2d picking routine?

It would be nice to merge the cartesian and gl2d hover logic at some point, but swapping in cartesian hover in gl2d probably means poor performance on graphs with 1e5 and up data points at this stage.

The problem is that mouseContainer intercepts mousemove, needed for cartesian selection to work. There seems to be no good way to hook up gl2d/camera so to enable cartesian/select − these are too separate concerns.
It is possible to switch to cartesian hover only for lasso/select mode, but the pick style differs visually, which is confusing.

Probably resolved by 1451802

This has no effect in gl2d. You must have added this in to make other things not break, correct?

Picking was broken without hoveron property

+                this.scatter.options.colors[4 * i + j] = color;


Very nice. Thanks for covering both updateFast and updateFancy !!

@dfcreative Something broke selection for fancy traces e.g. with array marker.size:

var x = []; var y = []; var size = [] for( var i = 0; i < 1e4; i++) { x.push(i); y.push(i*Math.random()); size.push(15 * Math.random()) } var scatterglMarkers = { x: x, y: y, type: "scattergl", mode: "markers", marker: {size: size, opacity: 1} }; console.time('scattergl') Plotly.newPlot('graph', [scatterglMarkers], {dragmode: 'lasso'}) .then(() => console.timeEnd('scattergl'))

Did you get the time to investigate ⤴️ ? If not, I can look at it this afternoon.

Well, looks like this was never implemented.

this.selectedIds in the scene2d.updateFancy scope doesn't reference anything.

@etpinard done.

Beautifully done. Thanks very much!

This is an interesting patch. I wonder if this might be fixing an undiscovered bugs(s).

monfera · 2017-06-10T17:19:52Z

Started leaning on this branch as this feature is essential for crossfiltering if the number of points is over around 1k. No specific need for it now, but at some point, maybe we'd want to add the properties curveNumber and pointNumber to elements of the eventData.points array for feature parity w/ scattergl. These numbers can work for indexing calcdata eg. gd.calcdata[curveNumber][pointNumber] (speaking of this object, at some point it could have the data property that gets fed from customdata). The eventData points already have the id which is all I need right now.

monfera · 2017-06-10T18:16:29Z

Quick perf check, it works well at 10k points as it's pushed rn:

It currently seems overly slow with 125k points where color is an array (haven't tested otherwise as crossfilter needs salient selected points):

Also, as seen on this 2nd animgif (also present with 10k points) the hover tooltip, for some reason, appears on initial render with no interaction (top left) and is stuck there even when mouse is moved (with or without hovermode: 'closest').

monfera · 2017-06-10T18:53:08Z

⬆️ cursory test shows that readPixels in

function SelectBuffer(gl, fbo, buffer) {
  this.gl     = gl
  this.fbo    = fbo
  this.buffer = buffer
  this._readTimeout = null
  var self = this

  this._readCallback = function() {
    if(!self.gl) {
      return
    }
    fbo.bind()
    gl.readPixels(0,0,fbo.shape[0],fbo.shape[1],gl.RGBA,gl.UNSIGNED_BYTE,self.buffer)
    self._readTimeout = null
  }
}

is the culprit (slow irrespective of how many of the 125k points is currently in the visible, zoomed domain):

@monfera may I ask you to help reproducing this bug with stuck hover tooltip? I faced it once, but it works fine rest of the time. Is some special scenario to that?

monfera · 2017-06-13T17:48:48Z

@dfcreative not showing up on my current branch right now, I'll make a minimal example if it occurs again

monfera · 2017-06-13T22:40:00Z

@dfcreative I don't have an isolated case, just a hint at this time - the tooltip seems to get stuck if I delete the marker.opacity line here:

Plotly.newPlot(
      plotlyChartHolder01,
      [{
        type: 'scattergl',
        mode: 'markers',
        marker: {
          size: 3,
          color: 'rgba(255,255,255, 0.25)',
          opacity: atomic.map(d => 1)
        },
        x: atomic.map(d => d.logValueMmUsd),
        y: atomic.map(d => d.logKilotons),
        ids: atomic.map(d => d.key),
      }],
      {
        hovermode: 'closest',
        dragmode: 'select',
        width: 500
      }
    )

In addition, when the opacity array is not present, and then do a rectangular lassoing (which is the initial state due to dragmode: 'select') there's an error complaining that positions === null. There are 2300 points. I can't work on a minimal case rn but thought to share it in case the above is a sufficient condition.

Painful! For some reason, these tests doesn't work on CI. Looks like the cases below can't even draw the scene:

https://circleci.com/gh/plotly/plotly.js/4535#tests/containers/1

Can anyone try to pull down this branch and try this out locally?

Works fine for me:

Although couple of times 'should output correct event data for scattergl' failed due to delay - in some reason karma runs chrome with blank tab, I have to manually switch to tests tab, but this is irrelevant.

etpinard · 2017-06-16T20:31:00Z

Would anyone be opposed to merging this without CI test support?

I can't figure out why these new tests keep failing on CircleCI. With the @noCI tag, they will run locally on npm run test-jasmine and be part of the pre-release checklist in ./tasks/noci_test.sh.
