ol4 + ol-ext problem with ol.featureAnimation.Zoom and ol.layer.AnimatedCluster - plugins

When I clicked over cluster, the features not show correctly, I tried stopping the animation but it didn't work. Is another option to show animation for each feature?
// Cluster Source
clusterSource = new ol.source.Cluster({
distance: distanceFt,
source: new ol.source.Vector()
});
// Animated cluster layer
clusterLayer = new ol.layer.AnimatedCluster({
name: 'Cluster',
source: clusterSource,
animationDuration: 700, //$("#animatecluster").prop('checked') ? 700 : 0,
// Cluster style
style: getStyle
});
// Transparent style to handle click on animation
var transparent = [0, 0, 0, 0.01];
var filltransparent = [0, 0, 0, 0];
var transparentStyle =
[new ol.style.Style(
{
image: new ol.style.RegularShape({ radius: 10, radius2: 5, points: 5, fill: new ol.style.Fill({ color: transparent }) }),
stroke: new ol.style.Stroke({ color: transparent, width: 2 }),
fill: new ol.style.Fill({ color: filltransparent })
})
];
// animation
var animacion = new ol.featureAnimation.Zoom({
fade: ol.easing.easeOut,
duration: 2000,
easing: ol.easing["easeOut"],
repeat: 100,
hiddenStyle: transparentStyle
});
ft_animados[idx] = vector_anim.animateFeature(anim_ft[i], animacion(anim_ft[i]));

I have two function:
function ft_animacion(f) {
//var style = f.getStyle();
var efecto = new ol.style.Style({
image: new ol.style["Circle"]({
radius: 30,
points: 4,
stroke: new ol.style.Stroke({ color: 'red', width: 2 })
})
});
f.setStyle(efecto);
return f;
}
function addFeatures(ffs, centrar) {
// some code lines
for (var i = 0; i < ffs.length; i++) {
features[i] = new ol.Feature();
features[i].setProperties(ffs[i]);
var geometry = new ol.geom.Point(transform([parseFloat(ffs[i].lon), parseFloat(ffs[i].lat)]));
features[i].setGeometry(geometry);
if (ffs[i].content.ind) {
if (ffs[i].content.ind.includes("Pendiente")) {
anim_ft.push(ft_animacion(features[i]));
}
}
}
// some code lines
}
I resolve my problem using feature.clone().
So edit the line anim_ft.push(ft_animacion(features[i])) to anim_ft.push(ft_animacion(features[i].clone()))
I dont noticed that when I use the function ft_animacion I was overwriting the style of feature.

Openlayers 6 : How to change PointStyle when selected?

I use Openlayers 6 try to change Point style when click on a point previously created but this code select the Point but no new style is applied. What Am i missing ?
I send the function to create the new Style, and the code to insert a Select Interaction
const styleClick = function(feature, resolution) {
return [
new Style({
image: new Circle({
fill: Fill({ color: [245, 121, 0, 0.8] }),
stroke: Stroke({ color: [0,0,0,1] }),
radius: 7
}),
text: new Text({
font: '24px Verdana',
text: feature.get('name'),
offsetY: 20,
fill: Fill({
color: [255, 0, 0, 0.8]
})
})
})
];
};
let selectSingleClick = new Select({style: styleClick});
map.addInteraction(selectSingleClick);
selectSingleClick.on('select', function (e) {
if( e.target.getFeatures().getLength() > 0 )
{
document.getElementById('obj-select').innerHTML =
' ' +
e.target.getFeatures().item(0).getGeometry().getType() +
' color is ' +
e.target.getFeatures().item(0).getStyle() +
' and deselected ' +
e.deselected.length +
' features)'
if( e.target.getFeatures().item(0).getGeometry().getType() == "LineString" )
{
//do something
};
if( e.target.getFeatures().item(0).getGeometry().getType() == "Point" )
{
//do something
};
//getGeometry().getCoordinates();
}
map.removeInteraction(selectSingleClick);
}
);
}
}
First, add your custom style like this:
let selectStyle = function (feature) {
let fill = new ol.style.Fill({
color: '#326de5',
});
let stroke = new ol.style.Stroke({
color: '#a30f4f',
width: 1.5
});
let styles = [
new ol.style.Style({
image: new ol.style.Circle({
fill: fill,
stroke: stroke,
radius: 6
}),
fill: fill,
stroke: stroke
})
];
return styles;
}
Now add top style to Select like this:
let selectInteraction = new ol.interaction.Select({
style: selectStyle
});
map.addInteraction(selectInteraction);
This code works for me!

Custom styling Google bar chart

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', {
packages: ['corechart']
}).then(drawHorizontalChart_portal_name_stella_york_horz_month_points);
function drawHorizontalChart_portal_name_stella_york_horz_month_points() {

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.

Axes Range change dynamically

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.
Plotly.d3.csv('https://raw.githubusercontent.com/plotly/datasets/master/3d-scatter.csv', function(err, rows) {
function unpack(rows, key) {
return rows.map(function(row) {
return row[key];
});
}
var trace1 = {
x: unpack(rows, 'x1'),
y: unpack(rows, 'y1'),
z: unpack(rows, 'z1'),
mode: 'markers',
marker: {
size: 12,
line: {
color: 'rgba(217, 217, 217, 0.14)',
width: 0.5
},
opacity: 0.8
},
type: 'scatter3d'
};
var trace2 = {
x: unpack(rows, 'x2'),
y: unpack(rows, 'y2'),
z: unpack(rows, 'z2'),

marker: {

};
var data = [trace1, trace2];
var layout = {
margin: {
l: 0,
r: 0,
b: 0,
t: 0,
}
};
Plotly.newPlot('myDiv', data, layout);
});

KineticJS dynamically change the position of an object when other object is moved

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/
