How to make Highcharts scrollbar always Visible?

I need to implement an scrollable column chart with Highcharts.
Question: How do I make the scrollbar always visible? Its visible when I try to scroll and hides back when not in use.
Highcharts.chart('container', {
chart: {
type: 'column',
scrollablePlotArea: {
enabled: true,
minWidth: 1800
},
marginRight: 30
},
scrollbar: {
enabled:true
},
title: {
text: 'Stacked column chart'
},
xAxis: {
categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas'],
scrollbar: {
enabled: true
},
},
yAxis: {
min: 0,
title: {
text: 'Total fruit consumption'
},
stackLabels: {
enabled: true,
style: {
fontWeight: 'bold',
color: ( // theme
Highcharts.defaultOptions.title.style &&
Highcharts.defaultOptions.title.style.color
) || 'gray',
textOutline: 'none'
}
}
},
legend: {
align: 'right',
x: -30,
verticalAlign: 'top',
y: 25,
floating: true,
backgroundColor:
Highcharts.defaultOptions.legend.backgroundColor || 'white',
borderColor: '#CCC',
borderWidth: 1,
shadow: false
},
tooltip: {
headerFormat: '<b>{point.x}</b><br/>',
pointFormat: '{series.name}: {point.y}<br/>Total: {point.stackTotal}'
},
plotOptions: {
column: {
stacking: 'normal',
dataLabels: {
enabled: true
}
}
},
series: [{
name: 'John',
data: [5, 3, 4, 7, 2]
}, {
name: 'Jane',
data: [2, 2, 3, 2, 1]
}, {
name: 'Joe',
data: [3, 4, 4, 2, 5]
}]
});

Hightchart issue, when more then one plot is used on page

I am working on page, where i need to have multiple plots, one being a solid gauge and the other being a line graph.
I am using the Ionic Framework 5 with angular and High Charts.
I am finding that when one plot is displayed, it works fine, but with more then one I am getting some type of conflict where the line chart does not get updated and the gauge gets data which is meant for the line graph.
This my code. Do i need to do anything in perticular?

How to change the color of single point in spiderweb chart

I'd like to change the color of a single point where its value is lower than 60%.
(For example, turn the blue color of two points which are in the pink area into a red color.)
Is this possible?
Thanks in advance!
Javascript:
Highcharts.chart('container', {
chart: {
polar: true,
type: 'line'
},
title: {
text: 'Budget vs spending',
x: -80
},
pane: {
size: '80%'
},
xAxis: {
categories: ['Sales', 'Marketing', 'Development', 'Customer Support',
'Information Technology', 'Administration'],
tickmarkPlacement: 'on',
lineWidth: 0
},
yAxis: {
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0,
max: 100
},
tooltip: {
shared: true,
pointFormat: '<span style="color:{series.color}">{series.name}: <b>${point.y:,.0f}</b><br/>'
},
legend: {
align: 'right',
verticalAlign: 'top',
y: 70,
layout: 'vertical'
},
series: [{
name: 'Allocated Budget',
color: 'blue',
pointPlacement: 'on',
data: [83, 79, 40, 35, 97, 80],
pointPlacement:'on',
}, {
name: 'lower than 60%',
data: [60,60,60,60,60,60],
pointPlacement: 'on',
lineWidth: 2,
type: 'area',
color: '#ffbce6',
dashStyle: 'shortdash',
}]
});
JS Fiddle

One of the options is to change the data for your Allocated Budget series to this:
data: [83, 79, {y:40, color:'red'}, {y:35, color:'red'}, 97, 80]

Highcharts - Can't change line colors

I'm looking to change the spider lines of the Highcharts spider web graph. I'm using a JSFiddle by someone else since mine isn't working for some reason.
I want to be able to change the line colors of the spider lines. What property do I change to get that?
$('#emotion-ranking-graph-bar').highcharts({
chart: {
polar: true,
type: 'line',
backgroundColor: 'rgba(255,255,255,0.0)'
},
exporting: {
enabled: false
},
title: {
text: '',
x: 0
},
pane: {
size: '80%'
},
xAxis: {
categories: ['Joy', 'Sorrow', 'Anger', 'Seriousness',
'Information Technology', 'Administration'],
tickmarkPlacement: 'on',
lineWidth: 0,
labels: {
enabled: true
}
},
yAxis: {
gridLineInterpolation: 'polygon',
lineWidth: 0,
min: 0,
color: 'rgba(255,255,255,1)',
labels: {
enabled: false
}
},
tooltip: {
shared: true,
pointFormat: '<span style="color:{series.color}">{series.name}: <b>${point.y:,.0f}</b><br/>'
},
legend: {
enabled: false
},
series: [{
name: 'Emotional Analysis Spectrum',
data: [43000, 19000, 60000, 35000, 17000, 10000],
pointPlacement: 'on',
color: 'rgba(0,0,0,0.7)'
}]
})

The lines going from the center to the outside are the yAxis, and the lines making the pentagon are the xAxis. You have to change the gridLineColor option on both:
