I want to get rid of the little dot in the top left of the tooltip box. I have been trying everything and it always seems to appear there. I have tried adding in "Marker: false", but maybe I am not inputting it in the correct spot (not sure if this is the correct code).

You can use formatter option for the tooltip, something like this, but add your values:
tooltip: {
formatter: function(tooltip) {
return `${question1}: <b>${percentage1}</b><br/>`
}
},
Here is documentation about it: https://api.highcharts.com/highcharts/tooltip.formatter

high charts starting new line from each point

I am using high charts to show energy data but i think due to some negative value high caharts starting a new line from each new point and lines not have any connection between them.
here is the picture of my results.
problem Image
you can see in the image there should be only one line.
here's my data for this.
I have 4 series's to show in graph but here i am only providing one because each line have same issue
var data={'vt':[[1588273200000, 0],[1586372400000, 245],[1586286000000, 200],[1586199600000, 7],[1586113200000, 4],[1586026800000, 1],[1585940400000, 4],[1588186800000, 40],[1585854000000, 7],[1588100400000, 30],[1588014000000, 155],[1587927600000, 38],[1587841200000, 57],[1587754800000, 35],[1587668400000, 66],[1587582000000, 68],[1587495600000, 35],[1587409200000, 40],[1587322800000, 62],[1585767600000, 8],[1587236400000, 37],[1587150000000, 44],[1587063600000, 72],[1586977200000, 13],[1586890800000, 5],[1586804400000, 58],[1586718000000, 90],[1586631600000, 41],[1586545200000, 186],[1586458800000, -498]]};

You need to provide an external graph value for z-index which will identify its position
Please go through this fiddle link with ur dataset. I have improved ur code.
So you can review it.
https://jsfiddle.net/vishalanand77/f6dnua28/32

You have unsorted data - Highcharts error #15: https://www.highcharts.com/errors/15/
You can sort it in this way:
data.vt.sort(function(a, b) {
return a[0] - b[0];
});

Ugly Highchart when using letter label for both xaxis and yaxis

I am trying to make the chart with both text label on xAxis and yAxis like this
Example
I am able to make it by this configuration
$(function() {
var chart = Highcharts.chart('chart-container', {
chart: {
type: 'bar',
},
title: {
text: '',
floating: true
},
legend: {
enabled: false
},
tooltip: {
pointFormat: '<b>{point.y:.2f}</b><br/>'
},
xAxis: {
gridLineColor: '#7F7F7F',
lineColor: '#7F7F7F',
gridLineWidth: 1,
tickLength: 0,
labels: {
align: 'left',
reserveSpace: true
},
categories: ['1. - 4. trinn (frivillige øvelser)', '1. - 4. trinn (obligatorisk ferdighetsprøve)', '5. - 7. trinn (frivillige øvelser)', '8. - 10. trinn (frivillige øvelser)']
},
yAxis: {
min: 31.83333,
max: 100,
title: {
text: null
},
gridLineWidth: 1,
tickLength: 0,
gridLineColor: '#7F7F7F',
lineColor: '#7F7F7F',
categories: {
'33.33333': 'Må øve mer',
'66.66667': 'På god vei',
'100': 'Kan'
},
tickPositions: [0, 33.33333, 66.66667, 100],
plotBands: [{
from: 31.83333,
to: 33.33333,
color: '#CC3333'
}, {
from: 65.16667,
to: 66.66667,
color: '#F2BA38'
}, {
from: 33.33333,
to: 34.83333,
color: '#CC3333'
}, {
from: 66.66667,
to: 68.16667,
color: '#F2BA38'
}, {
from: 97,
to: 100,
color: '#77B800'
}]
},
plotOptions: {
series: {
pointPadding: 0,
borderWidth: 0
}
},
series: [{
name: '',
color: '#646464',
borderColor: '#464646',
borderWidth: 1,
data: [0, 66.6666666666667, 0, 0]
}]
})
});

But you can see that it has a little bit "weird" at the 0 values, maybe it is a bug on Highchart?
Do you have another way to solve this?

Using this answer I was able to find a solution. Create yAxis categories as a variable and use the same function the answer uses to insert them, that is:
var categories = {0: '', 33.33333: 'Må øve mer', 66.66667: 'På god vei', 100: 'Kan'}
And then in the chart:
yAxis: {
labels: {
enabled: true,
formatter: function() {
return categories[this.value];
}
},
tickInterval: 1,
minPadding: 0,
maxPadding: 0,
startOnTick: true,
endOnTick: true,
...
}
