I am creating a graph with Cytoscape.js on my website, to show admins the connections among users. Everything is fine, but some graph are not drawn down. No errors in console, but the canvas seems empty.
For example, a graph that is not drawn has 20 EDGES and 18 NODES.
If I remove some edges, the graph is drawn and showed. No matter to which node or edge I remove: if I reach 18 EDGES it shows. So I thought "maybe it's too large".
But actually I have bigger graphs (37 edges) that are drawn without problems.
What can be the problem?
This is a graph that it's not showing. By the way, is there an online website where I can test this structure? Thanks

I am trying to do some Twitter-analysis via Twurl and extract some information via jq.
I firstly get some tweets via twurl with the command
twurl /1.1/users/search.json?q=judo
Then i used the following line to structure the outpot with jq:
twurl /1.1/users/search.json?q=judo | jq
i get something like this:

Because i am only interested in certain informations i tried to get the name and the text of the tweet with the following command:
twurl /1.1/users/search.json?q=judo | jq ".[] | { name: .name, text: .text }"
and i get this:
{
"name": "#JudoWorlds π₯",
"text": null
}
{
"name": "#WeAreGBJudo",
"text": null
}
{
"name": "CBJ",

}
Why is this and how can i fix it?
I tried other commands like :
twurl /1.1/search/tweets.json?q=afd | jq ".[] | { name: .name, text: .text }"
but got the error
jq: error (at <stdin>:0): Cannot index array with string "name"
If you need nested 'text' value from 'status' field you should use:
.[] | { name: .name, text: .status.text }
Or shorter version:
.[] | { name, text: .status.text }
I have a Highcharts bar graph. Each point has a group of results, however the first and last element are being cropped. How can I extend the x-axis so every bar is shown?
In the image below each group has the same results so you can see the N and P are dropped from the first group and S and Mg from the last grouping.
The data is coming from a database, so i don't know how many groups there will be, or what range (so simply adding a day to each end is not sufficient, the overlap could be larger or smaller)
const conf = {
chart: {
type: "column",
animation: false,
marginRight: 10,
dateFormat: "dd/mm/YYYY"
},
title: {
text: "Spread Events"
},
xAxis: {
type: "datetime",
tickPixelInterval: 50
},
yAxis: {
title: {
text: "Spread"

},
exporting: {

},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},

};
and this is the graphData from the example

}
]
You have Highcharts error #15 in a console, which means that your data is not sorted. Highcharts requires sorted data in ascending X order:
series: [{
...,
data: [
[1559257200000, 300],
[1559343600000, 300],
[1559669642443, 300]
]
}, ...

I'm trying to replicate this chart http://jsfiddle.net/edzk8Loe/ using vue js.
To be honest, I'm learning vuejs and so I'm trying to replicate already ready projects to get confident quickly.
The issue I'm facing at the moment I guess is a logic one. The functions have to create new series as drilldown when click on a column, seams not triggered at all. I'm not getting any error in the console and I'm
Not having yet a totally clear idea about the structure, I think I'm messing up the code. Hereunder you'll find the code I'm using in VUE.

I'm not looking for someone is doing the task instead of me, I won't learn anything. Ideas and tips are super welcomed.

You've made several simple mistakes in your code.
1) Add updateGraph function to chart methods - that way you can invoke this method in drilldown callback
2) Save chart component reference in the chart object to be able to use updateGraph method from drilldown callback function. You can make it using mounted() hook:
mounted() {
this.$children[0].chart.vueRef = this;
}
3) Data should be a function that returns an object with properties:
data() {
return {
chartOptions,
drilldownChart,
drilldownEvent,
drilldownLevel
}
}
4) Add drilldown and drillup callbacks to chart.events object. There you can invoke updateGraph method from the chart component reference saved in mounted hook:
chart: {
"type": "column",
events: {
drilldown: function(e) {
if (!e.seriesOptions) {
this.vueRef.updateGraph(true, this, e);
}
},
drillup: function(e) {
if (!e.seriesOptions.flag) {
this.vueRef.drilldownLevel = e.seriesOptions._levelNumber;
this.vueRef.updateGraph(false);
}
}
}
}

I'm trying to adapt particles.js to a Vue.js component from the example below:
https://codepen.io/MichaelVanDenBerg/pen/WpXGRm
However, when using the code below, I get the following error message in the console:
[Vue warn]: Error in mounted hook: "TypeError: this.particles is not a
function"
How can I fix it in the code below?

The particles.js package does not export anything, but rather it sets window.particlesJS.
To use this package, simply import it in your script, and then invoke particlesJS():
import 'particles.js'
export default {
// ...
methods: {
initParticles() {
window.particlesJS('particles-js', {/* ... */})
}
}
}
