How to put y axis of line chart to right when combined with bar chart in chart.js?

I have a graph where I am trying to draw a pareto chart by using chart.js. I am combining bar chart and line chart to achieve this. Here is my sample graph:
Here is the code:
this.chartData = {
labels: labels,
datasets: [
{
data: lineData,
label: "Cumulative Total of Number of Reassignments",
type: 'line',
fill: false,
datalabels: {
color: "#0f0f0f"
},
},
{
label: "Number of Reassignments",
data: datasetsLabel,
datalabels: {
color: "#0f0f0f"
}
},
]
}
lineData array holds the values 45.87, 64.22, etc.
datasetsLabel array holds the values 250, 100, 90, etc.
I tried to use the following options:
this.options = {
responsive: true,
scales: {
yAxes: [
{
ticks: {
stepSize: 5,
},
},
{
display: true,
position: 'right',
ticks: {
max: 100,
min: 0,
stepSize: 10
}
}
],
},
}
What I want to achieve is put 45.87, 62.22, etc values to the right side of the graph. How can I achieve this?

You can make use of the datalabels plugin

<canvas id="myChart" width="850" height="520"></canvas>
<script>
var ctx = document.getElementById('myChart');
Chart.register(ChartDataLabels);
Chart.defaults.set('plugins.datalabels', {
color: '#FE777B'
});
var myChart = new Chart(ctx, {
type: 'bar',
plugins: [ChartDataLabels],
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
data: [12, 19, 3, 5, 2, 3],
label: 'Advisor Closed MTD',
backgroundColor: 'rgb(192,111,94)',
barThickness: 25,
datalabels: {
color: '#FFCE56'
}
}],
},
options: {
indexAxis: 'y',
responsive: false,
plugins: {
datalabels: {
formatter: (val, context) => (`${val}%`),
anchor: 'end',

How to make pie slices in chartjs clickable (react-native)

I am working with a library that makes chartjs usable on react-native:
react-native-chartjs.
The chart works well, but when I press on the pie slices I only get the tooltip.
What I would like to, is to create my own function that will load a pop-up window instead of the tooltip provided by chart.js
How would you guys do it? Is it even doable? (I am pretty new to react-native, so sorry if it's a stupid question).

datasets: [

label: '# of Votes',

Chart.js 2.0 reduce gap between chart and y-axis

When the label is long, the y-axis is pushed to the left. It left a gap between the y-axis and the bar chart. Is there anyway to close the gap?
var labelList = ["Professional & Disciplinary Knowledge","Curriculum Planning and Instructional Delivery","Learning Environment","Creative Thinking","Problem solving and Critical Thinking","Research Skills"];
var barDatasource = {
labels: labelList,
datasets: [
]
};
var barConfig = {
type: 'bar',
data: barDatasource,
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
suggestedMax: 4
}
}],
xAxes: []
},
legend: {
position: 'bottom',
},
title: {
display: true,
text: 'Radar Chart for WM Component Mean',
fontSize: 14,
fontStyle: 'bold'
}
}
};
