JsPlumb, How to save connector labels?

Could someone help me out with what I am missing?
The scenario is: there are several nodes. Among them, one node can connect with 3 other nodes and those connections should be labeled.
The codes are connecting multiple nodes with labels, but on save it doesn't save the labels. On page load, it shows the connections but not the labels.
Here are my codes.
let connector = [
"EditableBezier",
{
cornerRadius: 0,
curviness: 30,
},
];
let paintStyle = {
strokeWidth: 2,
stroke: "rgb(217,217,217)",
outlineWidth: 3,
outlineStroke: "transparent",
};
let paintStyle = {
strokeWidth: 2,
stroke: "rgb(217,217,217)",
outlineWidth: 3,
outlineStroke: "transparent",
};
let hoverStyle = {
strokeWidth: 2,
stroke: "rgb(67,67,67)",
};
let abLabelCounter = 1;
function abSplitConnections(params) {
var source = params.connection.source;
var target = params.connection.target;
if (source.id === target.id) return false;
var conn = jsPlumb.getInstance();
let c = conn.connect({
source: source,
target: target,
editable: true,
anchor: "AutoDefault",
endpoint: "Blank",
connector: connector,
paintStyle: paintStyle,
hoverPaintStyle: hoverStyle,
overlays: [
[
"Arrow",
{
location: 1,
width: 10,
length: 10,
},
],
[
"Label",
{
location: 0.5,
label: () => {
if (abLabelCounter === 1) {
abLabelCounter++;
return "A";
}
if (abLabelCounter === 2) {
abLabelCounter++;
return "B";
}
if (abLabelCounter === 3) {
abLabelCounter = 1;
return "C";
}
},
id: "partition",
},
],
],
});
}

Highcharts: Value will not be updated

i have the next problem with Highcharts. This is a new Highchart for an other site.
See here: https://imgur.com/a/VQQLU
The arrow show to -3 Megawatts but the value at the bottom shows another value. At the first pageload the values are identical, but there comes all 5 seconds new values. And they are not updated at the bottom.
Edit: The tolltip will be updated correctly.
My code:
$(function () {
$.getJSON('jsonlive.php', function(chartData) {
var ADatum; var Eheit; var AktL; var MinL; var MaxL; var chartValue; var i;
ADatum = chartData[0].AktDatum;
Eheit = chartData[0].Einheit;
AktL = chartData[0].AktuelleLeistung;
MinL = chartData[0].MinLeistung;
MaxL = chartData[0].MaxLeistung;
var tMin = (MinL*-1); var tMax = MaxL;
var ttt = new Array();
if (tMin < tMax) { chartValue = tMax; } else if (tMin > tMax) { chartValue = tMin; } // Ermitteln ob neg/pos Zahl die größere ist.
ttt[0] = (chartValue*-1); // Skala mit Zahlen beschriften
for (i = 1; i < chartValue; i++) { ttt[i] = (i*-1); }
var tz = ttt.length ;
for (i = 0; i < chartValue; i++) { ttt[(tz+i)] = i; }
ttt[ttt.length] = chartValue;
var gaugeOptions = {
chart:{ events: {
load: function () { setInterval(function () {
$.getJSON('jsonlive.php', function(chartData) {
ADatum = chartData[0].AktDatum;
AktL = chartData[0].AktuelleLeistung;
var point = $('#inhalt').highcharts().series[0].setData([AktL], true);

});
});
</script>

The problem here is that you use a hard-coded value (AktL) in your dataLabels.format. In your example format is just a string that's used all the time.
Use {point.y} to have the label updated on every setData():
series: [{
data: [val],
dataLabels: {
// format: val // WONT WORK
format: '{point.y}'
}
}],

JQuery Flot - Grid lines not showing through filled lines

I'm trying to create one real-time flot and my problem is that I can't get to see the flot grid through the filling of my data's lines..
If you have any idea to get my filling a bit transparent like the picture below, I'd like to apply it as well on my Fiddle!
What I'm trying to achieve is something like that:
Picture of what I try to get
Here is the Fiddle on what I'm working:
My flot on Fiddle
Code:
$(function () {
getRandomData = function(){
var rV = [];
for (var i = 0; i < 10; i++){
rV.push([i,Math.random() * 10]);
}
return rV;
}
getRandomDataa = function(){
var rV = [];
for (var i = 0; i < 10; i++){
rV.push([i,Math.random() * 10 + 5]);
}
return rV;
}
getSeriesObj = function() {
return [
{
data: getRandomDataa(),
lines: {
show: true,
fill: true,
lineWidth: 5,
fillColor: { colors: [ "#b38618", "#b38618" ] },
tickColor: "#FFFFFF",
tickLength: 5
}
}, {
data: getRandomData(),
lines: {
show: true,
lineWidth: 0,
fill: true,
fillColor: { colors: [ "#1A508B", "#1A508B" ] },
tickColor: "#FFFFFF",
tickLength: 5
}
}];
}
update = function(){
plot.setData(getSeriesObj());
plot.draw();
setTimeout(update, 1000);
}
var flotOptions = {
series: {
shadowSize: 0, // Drawing is faster without shadows
tickColor: "#FFFFFF"
},
yaxis: {
min: 0,
autoscaleMargin: 0,
position: "right",
transform: function (v) { return -v; }, /* Invert data on Y axis */
inverseTransform: function (v) { return -v; },
font: { color: "#FFFFFF" },
tickColor: "#FFFFFF"
},
grid: {
backgroundColor: { colors: [ "#EDC240", "#EDC240" ], opacity: 0.5 }, // "Ground" color (May be a color gradient)
show: true,
borderWidth: 1,
borderColor: "#FFFFFF",
verticalLines: true,
horizontalLines: true,
tickColor: "#FFFFFF"
}
};
var plot = $.plot("#placeholder", getSeriesObj(), flotOptions);
setTimeout(update, 1000);
});
Thanks a lot!

You can use the rgba() color specification with flot to specify the fill color and alpha level (transparency):
fillColor: { colors: [ "rgba(179, 134, 24, .2)", "rgba(179, 134, 24, .2)" ] },
An alpha value of 0 is fully transparent, while an alpha value of 1 is fully opaque.

JointJS creating links from magnet not working

I managed to create a diagram with elements, in port, and multiple out ports.
All the elements are connected using links from the in port to an out port.
When I try to play with the links I already have (loaded from JSON), it works properly.
For some reason when I try to create a new link by pressing the ports, it drags the element instead.
How can I make the ports create new links when I press on them?

jsPlumb: Unable to make windows draggable

The original demo is here: https://jsplumbtoolkit.com/community/demo/flowchart/index.html
And the related js file which I have edited is this.
The node gets added and the endPoint elements are also added, but it is not draggable.

I got it working by making instance a global variable and calling it's draggable instead of the jsPlumb class.
Here's the modification:
var _addEndpoints;
var instance;
var idCount=5;
function addNode(){
idCount = idCount+1;
console.log($('#selector').find(":selected").text());
console.log("flowchartWindow"+idCount);

+'id="flowchartWindow'+idCount+'">'+
'<strong>'+$('#selector').find(":selected").text()+'</strong><br><br>'
+'</div>'
$("#canvas").append(new_item);
_addEndpoints("Window"+idCount);
instance.draggable(document.querySelectorAll(".flowchart-demo .window"), { grid: [20, 20] })
}
jsPlumb.ready(function () {
