I have a vertical and a horizontal lines and a circle on my stage, trying to keep the circle centered on the corssoing of the two lines when I move either line, here is my script that does not work:
var cy = 512;
var cx = 512;
var gy = 0;
var gx = 0;
var stage1 = new Kinetic.Stage({
container: 'container',
width: 1024,
height: 1024
});
var layer = new Kinetic.Layer();
var circle = new Kinetic.Layer();
var circle1 = new Kinetic.Circle({
x: cx + gx,
y: cy + gy,
radius: 140,
stroke: '#00ffff',
strokeWidth: 4,
opacity: 0.5
});
circle.add(circle1);
var GreenLine1 = new Kinetic.Line({
points: [0, 512, 1024, 512],
stroke: 'green',
strokeWidth: 4,
lineCap: 'round',
lineJoin: 'round',
opacity: 0.3
});
var BlueLine1 = new Kinetic.Line({
points: [512, 0, 512, 1024],
stroke: '#0080c0',
strokeWidth: 4,
lineCap: 'round',
lineJoin: 'round',
opacity: 0.5
});
var bgroup1 = new Kinetic.Group({
draggable: true,
dragBoundFunc: function (pos) {
return {
x: pos.x,
y: this.getAbsolutePosition().y
}
}
});
var ggroup1 = new Kinetic.Group({
draggable: true,
dragBoundFunc: function (pos) {
return {
x: this.getAbsolutePosition().x,
y: pos.y
}
}
});
bgroup1.add(BlueLine1);
ggroup1.add(GreenLine1);
layer.add(bgroup1);
layer.add(ggroup1);
stage1.add(circle);
stage1.add(layer);
BlueLine1.on('mouseover', function () {
document.body.style.cursor = 'e-resize';
});
BlueLine1.on('mouseout', function () {
document.body.style.cursor = 'default';
});
GreenLine1.on('mouseover', function () {
document.body.style.cursor = 'n-resize';
});
GreenLine1.on('mouseout', function () {
document.body.style.cursor = 'default';
});
ggroup1.on('dragend', function (event) {
var gy = ggroup1.getPosition().y;
circle.draw();
});
ggroup1.on('dragstart', function (event) {
circle1.moveTo(ggroup1);
});
bgroup1.on('dragstart', function (event) {
circle1.moveTo(bgroup1);
});
bgroup1.on('dragend', function (event) {
var gx = bgroup1.getPosition().x;
circle.draw();
});
I would appreciate your suggetions, thanks in advance
Keeping your circle in your crosshairs
May I suggest a simpler version of your code?
Instead of maintaining 2 groups and moving the circle between the 2 groups, how about just coding the circle to automatically redraw itself at the intersection of the 2 lines.
So when the user moves your GreenLine1 or BlueLine1, just move your circle1 to the intersection of your “crosshairs”.
First, add a custom drawFunc to your circle1 that causes it to always draw in the crosshairs:
drawFunc: function(canvas) {
var context = canvas.getContext();
var centerX=BlueLine1.getPosition().x;
var centerY=GreenLine1.getPosition().y;
context.beginPath();
context.arc(centerX, centerY, this.getRadius(), 0, 2 * Math.PI, false);
context.lineWidth = this.getStrokeWidth();
context.strokeStyle = this.getStroke();
context.stroke();
},
Then, whenever the user drags either line, just trigger circle1 to redraw itself:
// keep circle in center of crosshairs
stage1.getDragLayer().afterDraw(function() {
layer.draw();
});
Here is code and a Fiddle: http://jsfiddle.net/m1erickson/cgF8y/

Is there a possibility to accomplish a Google barchart to look like this?
The end of each bar with custom styling
Annotation comes below the line (GOAL 10.3)
you can use the chart layout method to add an icon, or any element, to the end of the bar.
// add icon to bar
var barBounds = layout.getBoundingBox('bar#0#0');
var icon = chart.getContainer().appendChild(document.createElement('span'));
icon.className = 'icon';
icon.style.top = (barBounds.top + containerBounds.top - 3) + 'px';
icon.style.left = (barBounds.left + containerBounds.left + (barBounds.width) - 24) + 'px';
icon.innerHTML = '<i class="fas fa-arrow-alt-circle-right"></i>';
also, instead of drawing the annotation and trying to prevent the chart from moving it,
we can leave it out and add our own custom annotation...
// add annotation
var labelCopy = svg.getElementsByTagName('text')[0];
var annotation = labelCopy.cloneNode(true);
svg.appendChild(annotation);
annotation.setAttribute('text-anchor', 'middle');
annotation.textContent = data.getValue(0, data.getNumberOfColumns() -1);
annotation.setAttribute('x', xLoc);
annotation.setAttribute('y',
layout.getYLocation(0) + (parseInt(annotation.getAttribute('font-size')) * 3)
);
see following working snippet...
google.charts.load('current', {

The OpenLayers example doesn't move smoothly as the only coordinates it uses are the points where the linestring changes direction. Therefore long straights are traversed much faster than the curved sections. The ol-ext method breaks the linestring into small equal length segments, but it seems to be animating the view to keep up with the marker instead of simply animating the marker. By reusing the splitLineString function from the second part of the answer to this question https://gis.stackexchange.com/questions/306976/add-image-along-the-linestring to finely divide the linestring and setting only one icon style based on a timer based index it is possible to achieve a smooth movement independently of the view (best seen in a full screen window) and also allows the icon to stay aligned with the direction of travel.

Does anybody know how can I change axis range in plotly's scatter3D via button click. I use relayout but it doesn't work
function updatet() {
Plotly.relayout(‘myDiv’, ‘zaxis.range’, [[0, 100]]);
}
Nothing happens (my range is still [0,1800])
For 3D plots zaxis.range needs to be inside scene in order to work.
Note: Your ticks look like some copy&paste/autoformat problem.

Right so I have my chart set up but the side labels or bar titles are cut off if they don't fit in the div of the graph, so my question is, is there anyway to overflow the bar titles of the graph(the font size is getting too small to read so I can't make it any smaller) or even wrap the text.
Well seeing as I don't think the code will help I'll show it regardless, mind you I have limited space and I am showing 2 graphs in that space. All I need is the side labels to have overflow: show(so if the specific bar label overflows the area it displays..

I've gone through the handy Famo.us University tutorials and am prototyping a drag & drop interface. It's the typical UI where the user can drag an icon and drop it onto a target to do something. I've gotten the drag part down, but detecting the drop is getting very hairy. Is there built-in collision detection in Famo.us?
Edit: I've looked at the Collision API but it's not clear whether this would work across views.
Here's how I've organized the project:
AppView (overall container)
|
|__ MenuView (sidebar) --> VizView (icons in MenuView)
|
|__ PageView (workspace where the drop targets live)
This may not be the best way to go about this. I'm not sure. Hooking up input events across the views seems to be painful.
VizView source:
/*** VizView.js ***/
define(function(require, exports, module) {
var View = require('famous/core/View');
var Surface = require('famous/core/Surface');
var Transform = require('famous/core/Transform');
var Modifier = require('famous/core/Modifier');
var ImageSurface = require('famous/surfaces/ImageSurface');
var Transitionable = require("famous/transitions/Transitionable");
var SnapTransition = require("famous/transitions/SnapTransition");
Transitionable.registerMethod("spring", SnapTransition);
var GenericSync = require('famous/inputs/GenericSync');
var MouseSync = require('famous/inputs/MouseSync');
var TouchSync = require('famous/inputs/TouchSync');
GenericSync.register({'mouse': MouseSync, 'touch': TouchSync});
function VizView() {
View.apply(this, arguments);
_createIcon.call(this);
}
VizView.prototype = Object.create(View.prototype);
VizView.prototype.constructor = VizView;
VizView.DEFAULT_OPTIONS = {
width: 200,
height: 100,
angle: -0.2,
iconSize: 98,
iconUrl: '',
title: 'Empty',
fontSize: 26
};
function _createIcon() {
this.zIndex = 0;
var me = this;
var iconSurface = new ImageSurface({
size: [this.options.iconSize, this.options.iconSize],
content : this.options.iconUrl,
properties: {
cursor: 'pointer'
}
});
var initModifier = new Modifier({
// places the icon in the proper location
transform: Transform.translate(24, 2, 0)
});
this.position = new Transitionable([0, 0]);
var positionModifier = new Modifier({
transform : function(){
var currentPosition = me.position.get();
return Transform.translate(currentPosition[0], currentPosition[1], me.zIndex);
},
});
var sync = new GenericSync(
['mouse', 'touch']
);
sync.on('start', function(data){
me.zIndex = 1;
});
sync.on('update', function(data){
me.updateIcon(data);
});
sync.on('end', function(data){
var velocity = data.velocity;
me.position.set([0, 0], {
method : 'spring',
period : 150,
velocity : velocity
});
me.zIndex = 0;
});
iconSurface.pipe(sync);
this.add(positionModifier).add(initModifier).add(iconSurface);
this.updateIcon = function (data) {
if (this.zIndex == 0) return;
var currentPosition = this.position.get();
this.position.set([
currentPosition[0] + data.delta[0],
currentPosition[1] + data.delta[1]
]);
}
}
module.exports = VizView;
});
A VizView is instantiated in MenuView as such:
var vizView = new VizView({
iconUrl: "path/to/iconUrl",
title: "Viz Title"
});
var vizModifier = new StateModifier({
transform: Transform.translate(0, yOffset, 0)
});
this.add(vizModifier).add(vizView);
A draggable Surface in Famo.us is not really a DOM draggable element although it can be setup to work in a browser using the mouse. I have not been able to get GenericSync and touch to work with this solution yet.
Reading the pitfalls on the Famo.us site, there are hints to drag and drop with surface draggables being an issue.
How do I find the absolute position of a Surface on the screen?
By design this is not possible. It is something the developer should
not care about. For the time being, this means that interactions such
as drag and drop are harder to implement, but this is intended and we
are working on an elegant solution for these use-cases.
Although: When not using GenericSync, you can use the DOM draggable events with a Famo.us Surface as you stated in the comments and link to the John Traver solution.
But: This solution will not work on mobile touch devices using Famo.us at the time of this answer. Getting this to work with touch may prove to be more difficult as stated in the pitfalls. Let's hope this gets solved in versions following 0.3.5 or in MixedMode (WebGL and DOM)
