Apexcharts cursor pointer

I used apexcharts.js for making chartbar on js. So i want to change cursor to pointer. help please! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
my-code!
var options = {
series: [{
name: 'series1',
data: [60, 85, 75, 120, 100, 109, 97]
}],
toolbar: {
show: false,
},
chart: {
height: 350,
type: 'area',
fontFamily: 'Proxima Nova',
toolbar: {
show: false
},
},
dataLabels: {
enabled: false
},
stroke: {
curve: 'smooth'
},
xaxis: {
categories: ["Янв", "Фев", "Март", "Апр", "Май", "Июнь", "Июль", "Авг", "Сен", "Окт", "Ноя", "Дек"]
},
tooltip: {
x: {
format: 'dd/MM/yy HH:mm'
},
},
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

I had encountered the same problem. I will present you two solutions:
1st method : Found on Github
You can set the cursor to point with:
chart: {
...
events: {
dataPointMouseEnter: function(event) {
event.path[0].style.cursor = "pointer";
}
}
}
See more details in this github link : https://github.com/apexcharts/apexcharts.js/issues/1466
2nd method : My own method
You can target the class name of the apexchart component via Inspector, then at the code level add the following property to this class :
cursor: pointer
Example :
// Change cursor on hover
.apexcharts-pie {
cursor: pointer;
}

I had same problem. Here is two solutions:
chart: {
width: 320,
type: ...,
events: {
dataPointMouseEnter: function(event) {
event.target.style.cursor = "pointer";
// or
event.fromElement.style.cursor = "pointer";
}
},
}

HighCharts inside of a javascript function

I'm trying to draw a 3d box after a user has selected some data from the server.
When I put the highcharts inside of a js function, it throws some errors.
My code is:
Chart It<br/>
<div id="container" style="height: 400px"></div>
<script>
var chart;
function chart3d() {
// Give the points a 3D feel by adding a radial gradient
Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: {
cx: 0.4,
cy: 0.3,
r: 0.5
},
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.2).get('rgb')]
]
};
});
// Set up the chart
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
margin: 100,
type: 'scatter',
options3d: {
enabled: true,
alpha: 10,
beta: 30,
depth: 250,
viewDistance: 5,
fitToPlot: false,
frame: {
bottom: {
size: 1,
color: 'rgba(0,0,0,0.02)'
},
back: {
size: 1,
color: 'rgba(0,0,0,0.04)'
},
side: {
size: 1,
color: 'rgba(0,0,0,0.06)'
}
}
}
},
title: {
text: 'Draggable box'
},
subtitle: {
text: 'Click and drag the plot area to rotate in space'
},
plotOptions: {
scatter: {
width: 10,
height: 10,
depth: 10
}
},
yAxis: {
min: 0,
max: 10,
title: null
},
xAxis: {
min: 0,
max: 10,
gridLineWidth: 1
},
zAxis: {
min: 0,
max: 10,
showFirstLabel: false
},
legend: {
enabled: false
},
series: [{
planeProjection: {
enabled: false,
},
lineProjection: {
enabled: 'hover',
colorByPoint: true
},
name: 'Reading',
colorByPoint: true,
data: darray
}]
});
// Add mouse events for rotation
$(chart.container).on('mousedown.hc touchstart.hc', function (eStart) {
eStart = chart.pointer.normalize(eStart);
var posX = eStart.pageX,
posY = eStart.pageY,
alpha = chart.options.chart.options3d.alpha,
beta = chart.options.chart.options3d.beta,
newAlpha,
newBeta,
sensitivity = 5; // lower is more sensitive
$(document).on({
'mousemove.hc touchdrag.hc': function (e) {
// Run beta
newBeta = beta + (posX - e.pageX) / sensitivity;
chart.options.chart.options3d.beta = newBeta;
// Run alpha
newAlpha = alpha + (e.pageY - posY) / sensitivity;
chart.options.chart.options3d.alpha = newAlpha;
chart.redraw(false);
},
'mouseup touchend': function () {
$(document).off('.hc');
}
});
});
}
</script>
This loads fine if I do not put it inside of the chart3d function. Is there a way to get this working. The error message I get is:
highcharts.js:10 Uncaught Error: Highcharts error #13: www.highcharts.com/errors/13
at Object.a.error (highcharts.js:10)

at new a.Chart (highcharts.js:246)
at chart3d (graphingCustom.js:26)
at HTMLAnchorElement.onclick (VM599 :643)

As they say:
Highcharts Error #13
Rendering div not found
This error occurs if the chart.renderTo option is misconfigured so that
Highcharts is unable to find the HTML element to render the chart in.
You don't have a div with the id=container at the time you are calling the method.

jointjs: svg text is replaced by blank on drop to paper

In stencils we have png, on drop to paper we replace cell[png] with svg.
cell - represents png
vectorString - markup of png
var currentSvg = new joint.shapes.basic.pwmeter({
position: { x: bbox.x, y: bbox.y },
size: { height: cell.attributes.minHeight, width: cell.attributes.minWidth },
minWidth: cell.attributes.minWidth,
minHeight: cell.attributes.minHeight,
markup: vectorString,
type: cell.attributes.type,
fileName: cell.attributes.fileName,
isInteractive: true,
elementClassName: cell.attributes.elementClassName,
isAnimatedDevice: cell.attributes.isAnimatedDevice,
attrs: {
'.myClass': {
fill: '#ffffff',
stroke: '#000000'
}
}
});
currentSvg.addTo(Rappid.graph);
we are making pwmeter by extending Image
joint.shapes.basic.pwmeter = joint.shapes.basic.Image.extend({
type: 'basic.pwmeter',
initialize: function () {
return joint.shapes.basic.Image.prototype.initialize.apply(this, arguments);
}
});
We drop png from stencils to paper, and get svg markup for corresponding png,
we call currentSvg.addTo(Rappid.graph), during execution of this, all text in meter [svg] are replaced by blank.
our text - 0
auto generated code replaces my text, we are not able to figure out why this is happening
-
above is the generated text
We are new to jointjs, we think we are doing something wrong during extending.

I can see there is a markup in you settings. Make sure there is a text 'placeholder' in the markup.
in this example attr text is tied with the <text/> element
new joint.shapes.basic.pwmeter({
markup: '<g><image/><text/></g>',
attrs: {
text: { text: '48x48' },
image: { 'xlink:href': 'http://placehold.it/48x48', width: 48, height: 48 }
},
size: { width : 50, height: 50 },
position: { x:200, y: 50},
}).addTo(graph)
but in here, attr text has no matching element in the markup, therefore it won't be rendered.
new joint.shapes.basic.pwmeter({
markup: '<g><image/></g>',
attrs: {
text: { text: '90x90' },
image: { 'xlink:href': 'http://placehold.it/90x90', width: 90, height: 90 }
},
size: { width : 90, height: 90 },
position: { x:50, y: 50},
}).addTo(graph)
more information about attr property could be found here http://resources.jointjs.com/docs/jointjs/v1.0/joint.html#joint.dia.Element.presentation

Joint JS - How apply an event on shapes.devs

I'm new with jointjs and I try to constraint a rectangle with ports to a line.
I tried to reproduce tutorial, that works with a basic.Circle, with a basic.Rect but not with devs.Model
Could someone explian me why and how to solve this problem?
Many thanks in advance!
Here is my code :
var width=400, height=1000;
var ConstraintElementView = joint.dia.ElementView.extend({
pointermove: function(evt, x, y) {
joint.dia.ElementView.prototype.pointermove.apply(this, [evt, 100, y]);
}
});
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({ el: $('#myholder'), width: width, height: height, gridSize: 1, model: graph, elementView: ConstraintElementView});
var m1 = new joint.shapes.devs.Model({
position: { x: 20, y: 20 },
size: { width: 90, height: 90 },
inPorts: [''],
outPorts: [''],
attrs: {
'.label': { text: 'Model', 'ref-x': .4, 'ref-y': .2 },
rect: { fill: '#2ECC71' },
'.inPorts circle': { fill: '#16A085' },
'.outPorts circle': { fill: '#E74C3C' }
}
});
var m2=m1.clone();
m2.translate(0,300);
var earth = new joint.shapes.basic.Circle({
position: { x: 100, y: 20 },
size: { width: 20, height: 20 },
attrs: { text: { text: 'earth' }, circle: { fill: '#2ECC71' } },
name: 'earth'
});
graph.addCell([m1, m2, earth]);

Why does it not work?
devs.Model is not rendered via ContraintElementView to the paper.
devs.Model uses devs.ModelView for rendering, basic.Circle and basic.Rect use ContraintElementView.
JointJS dia.Paper searches for a view defined in the same namespace as the model first. If found, it uses it. It uses one from the paper elementView option otherwise. i.e. joint.shapes.devs.ModelView found for devs.Model but no view found for basic.Circle (no joint.shapes.basic.RectView is defined)
How to make it work?
define elementView paper option as a function. In that case paper don't search the namespace and uses the result of the function first.
Note that in order to render ports devs.ModelView is still required.
i.e.
var paper = new joint.dia.Paper({
elementView: function(model) {
if (model instanceof joint.shapes.devs.Model) {
// extend the ModelView with the constraining method.
return joint.shapes.devs.ModelView.extend({
pointermove: function(evt, x, y) {
joint.dia.ElementView.prototype.pointermove.apply(this, [evt, 100, y]);
}
});
}
return ConstraintElementView;
}
});
http://jsfiddle.net/kumilingus/0bjqg4ow/
What is the recommended way to do that?
JointJS v0.9.7+
not to use custom views that restrict elements movement
use restrictTranslate paper option instead.
i.e.
var paper = new joint.dia.Paper({
restrictTranslate: function(elementView) {
// returns an area the elementView can move around.
return { x: 100, y: 0, width: 0, height: 1000 }
};
});

Putting multiple films in a circle in Raphael/Joint.js

I have an FSA in joint.js, and I need to make the states (circles) semi-filled to specific ratios, like 1/2 or 1/6, starting from the bottom of the circle. The tricky part is that it needs to be done twice - A larger semi-fill and a smaller semi-fill over it.
This is what i am trying to do:
I'm lost as to how to accomplish this.

The trick is to create three SVG circles and define clip paths for them. The following example creates a custom JointJS shape (inheriting from fsa.State) with custom SVG markup that enables the coloring that you have shown in the image:
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({ el: $('#paper'), width: 650, height: 400, model: graph });
joint.shapes.fsa.MyState = joint.shapes.fsa.State.extend({
markup: [
'<g class="rotatable"><g class="scalable">',
'<clipPath id="clip-top1"><rect x="-30" y="0" width="60" height="30"/></clipPath>',
'<clipPath id="clip-top2"><rect x="-30" y="15" width="60" height="30"/></clipPath>',
'<circle class="a"/><circle class="b"/><circle class="c"/>',
'</g><text/></g>'
].join(''),
defaults: joint.util.deepSupplement({
type: 'fsa.MyState',
size: { width: 60, height: 60 },
attrs: {
'circle': { fill: 'white' },
'.b': { fill: 'red', 'clip-path': 'url(#clip-top1)' },
'.c': { fill: 'blue', 'clip-path': 'url(#clip-top2)' }
}
}, joint.shapes.fsa.State.prototype.defaults)
});
var mystate1 = new joint.shapes.fsa.MyState({
position: { x: 50, y: 50 },
size: { width: 100, height: 100 },
attrs: { text: { text: 'my state 1' } }
});
graph.addCell(mystate1);
var mystate2 = new joint.shapes.fsa.MyState({
position: { x: 50, y: 160 },
size: { width: 50, height: 50 }
});
graph.addCell(mystate2);
