Can I use parameter to define field name - javascript

The following JavaScript code works, but is there a more compact way to write it using n parameter, to "eval" y1axis, y2axis, y3axis field names?
switch (n) {
case 1:
markingsY = [
{ color: colorErr, y1axis: { from: maxVal } },
{ color: colorErr, y1axis: { to: minVal } },
{ color: "#00f", lineWidth: 1, y1axis: { from: minVal, to: minVal } },
{ color: "#00f", lineWidth: 1, y1axis: { from: maxVal, to: maxVal } }
];
break;
case 2:
markingsY = [
{ color: colorErr, y2axis: { from: maxVal } },
{ color: colorErr, y2axis: { to: minVal } },
{ color: "#00f", lineWidth: 1, y2axis: { from: minVal, to: minVal } },
{ color: "#00f", lineWidth: 1, y2axis: { from: maxVal, to: maxVal } }
];
break;
case 3:
markingsY = [
{ color: colorErr, y3axis: { from: maxVal } },
{ color: colorErr, y3axis: { to: minVal } },
{ color: "#00f", lineWidth: 1, y3axis: { from: minVal, to: minVal } },
{ color: "#00f", lineWidth: 1, y3axis: { from: maxVal, to: maxVal } }
];
break;
default:
break;
}

Edit: Misread the question, Sorry!
You could use a static key instead of the one you need to change, then change it dynamically, so:
markingsY = [
{ color: colorErr, yaxis: { from: maxVal } },
{ color: colorErr, yaxis: { to: minVal } },
{ color: "#00f", lineWidth: 1, yaxis: { from: minVal, to: minVal } },
{ color: "#00f", lineWidth: 1, yaxis: { from: maxVal, to: maxVal } }
];
markingsY.forEach(function(item){
item["y"+n+"axis"]=item.yaxis;//copy it to its new key
delete item.yaxis;//remove the old one
});

Try:
var n = 10
var collections = [];
for(var i = 0; i < 10; i++){
var json1 = {}
var row = [];
json1['color'] = '#000000';
json1['y'+i+'axis'] = {from: 1234};
row.push(json1);
collections.push(row);
}
console.log(collections);
You will have the collection of 10 markingsY arrays.
each markingsY array has (my code) 1 JSON
collections = [
[{color:#0000000, y0axis:{form:1234}}],
[{color:#0000000, y1axis:{form:1234}}]
.....];
Then your switch(n) can be replaced:
collections[n]

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: {

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}'
}
}],

Split Overlap Ranges

I have implemented an algorithm for dividing overlapping existing ranges into a list of date / number ranges.
The algorithm is working but I was wondering if you can avoid the last loop of the algorithm.
It's possible?

90-150(green)
90-150(blue)
140-300(yellow)

50-500(silver)
50-60(pink)
Output Data
0-49(red)
50-60(red,silver,pink)
61-89(red,silver)
90-100(red,green,blue,silver)

return a - b;

You need some iterations, at least the one with getting all range points, and then generate an array out of it and take the subset of colors for each small interval.
var data = [{ from: 0, to: 100, color: 'red' }, { from: 90, to: 150, color: 'green' }, { from: 90, to: 150, color: 'blue' }, { from: 140, to: 300, color: 'yellow' }, { from: 170, to: 240, color: 'black' }, { from: 350, to: 530, color: 'orange' }, { from: 50, to: 500, color: 'silver' }, { from: 50, to: 60, color: 'pink' }],
ranges = new Set,
parts,
result;
data.forEach(({ from, to }) => (ranges.add(from), ranges.add(to)));
parts = [...ranges].sort((a, b) => a - b);
result = parts.slice(1).map(function (a, i, aa) {
var from = i ? aa[i - 1] : parts[0],
to = a,
colors = data.filter(d => d.from <= from && to <= d.to).map(({ color }) => color);
return { from, to, colors };
});
console.log(result);

Flot Bar and Line chart [duplicate]

I've made this bar chart http://imageshack.com/a/img901/7186/cnOfhh.png, and the code for it is:

Can anyone help me with a suggestion to start with to get the same bar chart like in the last image?
Here is something like your second picture using another bar dataseries where the start and end of the bars are the same thereby reducing them to lines, you don't need to stack any of the bars just give them the right y-values (fiddle):
$(function () {
var dataBarsRed = {
data: [
[2, 3], ],
label: 'Bars in Red',
color: 'red'
};
var dataBarsGreen = {
data: [
[1, 2],

[4, 3]

label: 'Bars in Green',

var dataLines = {
