I am attempting to create the following chart:
However I can't seem to get the plotbands to work in this way; right now, they fill the entire axis:
I am not sure if I should use annotations instead, but so far I haven't gotten it to work. What can I try next?

This kind of plotBand shape is not possible from the API level, but you can simulate it in several ways. Example configurations:
SVG Renderer:
chart: {
events: {
render() {
const chart = this;
if (chart.rects) {
chart.rects = chart.rects.destroy();
}
chart.rects = chart.renderer.g('rects').attr({
zIndex: 1
}).add();
let x = chart.xAxis[0].toPixels(1),
y = chart.yAxis[0].toPixels(4),
width = chart.xAxis[0].toPixels(2) - chart.xAxis[0].toPixels(1),
height = chart.yAxis[0].toPixels(2) - chart.yAxis[0].toPixels(4);
chart.rect = chart.renderer.rect(x, y, width, height)
.attr({
fill: 'grey'
}).add(chart.rects)
chart.rect = chart.renderer.rect(chart.xAxis[0].toPixels(3), y, width, height)
.attr({
fill: 'grey'
}).add(chart.rects)
}
}
},

The yAxis values min and max are set to 0 and 100 with a tick interval of 20 by me.
But when the resolution is changed to a lower resolution or the chart is zoomed in,
I have observed that the height of the high hart decreases and the max value is set to 120 and tick interval to 40 on its own
Which is not the desired behavior can you please help me out how to avoid it?
How can i make sure the max is 100 with a tickinterval 20 in all chart heights and also in turn in lower resolution.
Thanks in advance
Note:- I believe the height is decreased because the xAxis labels rotate diagonally as the width is decreased (in lower resolution) and that occupies more space in the HTML div and causes the height of the chart to decrease.
YAxis with expected behaviour
YAxis in lower resolution with decreased height

Just like you have noted - there is not enough space to render 5 labels for some smaller dimensions, so implemented logic tries to calculate other timestamps, which will fit, like [0, 40, 80, 120].
I think that you can control it by using the responsive options and set the tickInterval to another value like 50.
Demo: https://jsfiddle.net/BlackLabel/zupbe174/
responsive: {
rules: [{
condition: {
maxHeight: 120
},
chartOptions: {
yAxis: [{
tickInterval: 50
}, {
}]
}
}]
}
API: https://api.highcharts.com/highcharts/responsive.rules.condition
The plotline should spread across the graph but the plot band should of smaller width.
1) Initially without width being set.
2) When y axis width is set to 20
3) I want something like this where both the plot band and the plotline co exists
this is the fiddle code link to what I have tried so far.
Can someone please help me out thank you very much in advance.

The simplest solution is to create another y-axis and move plot bands to it:
yAxis: [{
...,
plotLines: [...],
}, {
...,
plotBands: [...]
}]

FIDDLE LINK
This is how I want it to look like : Instead of '2' in the top circles , it should be the corresponding value from the center spline [1, 2, 5, 3, 6, 7, 4]
1) The plotLines are infinite. The extend as far as the plot area is. So, to limit this, how about you change your yAxis max:
yAxis: {
max: 8,
labels: {
enabled: false
},
title: {
enabled: true,
text: null
}
},
Or, you could create a column series on the points you want and give them a certain value for the height you want. Making the columns thin to mimic your plotLines will help like so:
series: [{
name: '',
type: 'column',
pointWidth: 1,
borderWidth: 0,
data: [8, 8, 8, 8, 8, 8, 8]
},
...
2) Which values in the circles (I am guessing)? The "Series 1: XX"? Or the whole tooltip?
EDIT:
For question 2 you can do this with a formatter function on the dataLabel for the scatter series (your circles). Here is the function:
var customFormatPoint = function (pointX, seriesIndex) {
var theChart = $('#container').highcharts();
var yValue = null;
var points = theChart.series[seriesIndex].options.data[pointX];
return points;
};
You call this from:
series: [{
name: '',
type: 'column',
pointWidth: 1,
borderWidth: 0,
dataLabels: {
enabled: true,
formatter: function () {
return customFormatPoint(this.point.x, 1);
}
},
data: [7.70, 7.70, 7.70, 7.70, 7.70, 7.70, 7.70]
}, {...
Key element here is that you have this.point.x which is that scatter point's xAxis location. You then need to send in which index the series is that contains the y value you want to show in the dataLabel.
I have also removed the plotLines and created a series that just contains the bars with width of 1 and no border. I had to mess around to get the end of the bar (its max value) to coincide with the scatter circle diameter.
Please see this jsFiddle.

Many Thanks,
First of all I see that you have empty series.data which doesn't exists. In case when you download data by ajax, you push your data to series or use i.e setData() / addPoint() functions. All of them are documented here: http://api.highcharts.com/highcharts
I advice to familiar with article about preprocessing data http://docs.highcharts.com/#preprocessing
