I created two x,y arrays and then performed two chart using these. I want to write some texts in only Chart red one. And I want to use (x,y) coordinates to determine text region.
I try to Chartjs Global plugin but it causes to writing text all charts. I demand texting only one chart.
I could not succeed in Chartjs mono Plugin in Script.
Please Help Me.

UPDATE:
Here is another problem:
Is there any way to assign text position via chartjs coordinate system, in stead of "width., height."?
For instance, according to xCoord & yCoord arrays, is it possible to set the position of ctx.fillText x,y coordinates:
In stead of ctx.fillText("s(A)", width * .28, height * .70); can be like this : ctx.fillText("s(A)", 2005, 3); (2015,9) is belong to chartjs coordinate system.
My Aim:
s(A) can be seen on chartjs area at the point of (2005,3)
s(A) can be seen on chartjs area at the point of (2015,9)

Create and register a new plugin that draw the text, then call it only on the second chart, you can pass data as well (like an array of labels and the locations of each for example).
Update: (register plugins)
If you register a plugin globally then, you will have to disable the plugin in each chart here you don't want it to run.
options: {
plugins: {
plugin: false
}
}
- or -
If you don't register the plugin globally, in each chart that you need to add the labels add the following:
{
plugins: [plugin]
}
Note: In the second snippet of code plugin is not nested under options. Seen here.
Update: (display text using x,y datasets)
In order to use a x,y value you need to identify the axes you what the value from using its id, the defaults are x-axis-0 and y-axis-0, that increments if you add more axes. Or use a custom axis id.
After that, within the chart instance there is a scale object that represents the axis and using chart.scales['x-axis-0'] you can access a function called getPixelForValue which will convert the giving value from that axis to its pixel location.

Here is problem. The text is written all charts. My aim is only red one chart (My Chart 2).

Using cytoscape.js, I am setting the style of a node while defining it.
Shortened example below:
window.addEventListener('DOMContentLoaded', function(){
var cy = window.cy = cytoscape({
elements: {
nodes: [
{ data: { id: 'a', name: 'apple' }, style: { 'background-color': 'darkgreen' } },
]
}
});
});
(I have a default style for a node that is a different color)
This works fine, but when I run my code, the browser console shows the following warning:
Setting a `style` bypass at element creation is deprecated
What does it mean and what is the correct (non-deprecated) way to set it?
Thank you in advance!
The correct way of doing this would be to use the cytoscape stylesheet, as can be seen in every example in the docs:
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
boxSelectionEnabled: false,
autounselectify: true,
style: [{
selector: "node",
css: {
"label": "data(id)",
"text-valign": "center",
"text-halign": "center",
"background-color": "data(color)"
}
},
{
selector: "edge",
css: {
"line-fill": "radial-gradient",
"line-gradient-stop-colors": "red green blue",
"line-gradient-stop-positions": "25 50 75"
}
}
],
elements: {
nodes: [{
data: {
id: "a",
color: "#2763c4"
}
},
{
data: {
id: "b",
color: "#37a32d"
}
},
{
data: {
id: "c",
color: "#37a32d"
}
}
],
edges: [{
data: {
source: "a",
target: "b"
}
},
{
data: {
source: "a",
target: "c"
}
}
]
},
layout: {
name: "dagre"
}
}));
cy.ready(function() {
cy.dblclick();
});
var nid = 0;
cy.bind('dblclick', function(evt) {
console.log('dblclick');
cy.add({
group: 'nodes',
data: {
id: nid,
faveColor: 'red'
},
position: {
x: evt.x,
y: evt.y
}
});
nid++;
});
cy.bind('click', 'node', function(evt) {
console.log('node clicked: ', evt.target.id());
});
body {
font: 14px helvetica neue, helvetica, arial, sans-serif;
}
#cy {

I initialized the cytoscape like this:
var cy = cytoscape({
container: document.getElementById('cy'),
elements: [
{ data: { id: 'a' } },
{ data: { id: 'b' } },
{ data: { id: 'c' } },
{
data: {
id: 'ab',
source: 'a',
target: 'b'
}
},
{
data: {
id: 'ac',
source: 'a',
target: 'c'
}
}
]
});
Then I added a function which adds a new node whenever the user double clicks on the viewport.
var nid = 1;
document.getElementById("cy").ondblclick = function(e) {
cy.add({ data: { id: nid }, renderedPosition: { x: e.x, y: e.y } });
nid++;
};
Then I wrote this function which should be called whenever user clicks a node. It works whenever user clicks on a node which I added manually when initializing the cytoscape but the problem is its not working for the nodes which user added by double clicking.
cy.$('node').on('click', function (e) {
console.log('node clicked: ', e.target.id());
});
Any idea what am I doing wrong?

I used the cy.on()/cy.bind() method, that seems to work with newly added nodes :)
I want to make an animation for each edge that I'm visiting sequentially, but when I try to do that the animation is done for all the edges at the same time, how can I fix this?
cy.edges().forEach(e => {
let src = parseInt(e.source().data('id'))
let trg = parseInt(e.target().data('id'))
let w = parseInt(e.style('label'))
e.animation({
'style': {'line-color': '#FF0000'}},
{'duration': '2000'}).play()
}

So instead of going for the bfs path, you can define your own path and use the higlighting function of the demo.
Good luck
I first create a graph with 100's of connected nodes. After all the nodes have been added I call
cy.layout({name: "dagre"});
Next, I'm creating 5 or so additional connected nodes I call layout on the nodes added but it doesn't lay them out as expected. Instead of being more like a tree all the nodes are in a straight line.
It looks like this:
var collection = cy.collection();
collection.merge(eles);
...
// I merge in another 5 newly created nodes.
// Next I call layout
collection.layout({
name: "dagre", fit: false,
boundingBox: {
x1: mousex - width / 2, y1: mousey - height / 2, x2: mousex + width, y2: mousey + height
},
nodeSep: 30
}).run();
But I expect it to look like the image below.
In order to get it to look like the above, I call layout shown below.
cy.layout({name: "dagre"});
I've looked through all the options for a dagre layout and can't find anything to make it create the tree.
Edit: The dagre layout needs nodes and edges to calculate the right positions for the nodes, the way you use it, dagre thinks you give it 5 seperate nodes, which explains your wrong layout. The mistake lies here:
collection.merge(eles); // here you should add all relevant nodes and edges
End
I have an example for you --->here<---, just copy that and add your real data:
var cy = (window.cy = cytoscape({
container: document.getElementById("cy"),
boxSelectionEnabled: false,
autounselectify: true,

selector: "node",
css: {

"background-color": "data(faveColor)"
}
},

}

]
},
layout: {

}
}));
cy.ready(function () {
setTimeout(function () {
cy.nodes().layout({ name: 'dagre' }).run(); // this is what you do!!

I Serialized my data in code behind as;
Dim classes As List(Of SerializedJsonDT) = SerializedJsonDT.GetJsonFriendlyClasses(dt)
jsonNTMS = JsonConvert.SerializeObject(classes)
Then I received this data from aspx page as;
<script type="text/javascript">
var obj = JSON.parse('<%=jsonNTMS%>');
var catName = obj[0].name;
var ser1Name = obj[1].name;
var ser2Name = obj[2].name;
var catData = obj[0].data;
var ser1Data = obj[1].data;
var ser2Data = obj[2].data;
var cSstopHere2 = 2;
var chart;
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
height: 400,
width: 600,

});
chart.redraw
});
</script>
I can see my chart container but only the categories shown. I cant see my series in my highchart.
The web form I have;
<body>
<script src="http://code.highcharts.com/highcharts.js" type="text/javascript"></script>
<script src="http://code.highcharts.com/modules/exporting.js" type="text/javascript"></script>
<form id="form1" runat="server">
<div id="container" style="min-width: 400px; height: 400px; margin: 0 auto"></div>
</form>
</body>
Does anyone knows how to make my highcharts shows my series?
My categories was time values and I convert them to string before serialized. (08:17, 09:45 etc). And my series data originally was decimal values and I convert them to string before serialized. I did place ser1Data first and didn't work. So I try to use set data events. I guess I have to convert my series data in javascript to decimal. But I rather use this process in my custom "Public Class SerializedJsonDT" class. mason help me to build the class.
Kind Regards...
