I am using Chart.js to create a chart with three datasets. It is a line chart and the points are dynamically generated using PHP.
Now, I want to know how can I only show one dataset as default? but I still want all the legends to show but the rest must appear crossed out. So when a user clicks those crossed out legends, they may appear on the chart.
I can provide my chart but that would be of no use I believe. Anyways:
var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
labels: [<?php foreach ($data0 as $key => $value) {
echo "'".$value->updated_at->format('gA-D')."',";
} ?>],
datasets: [{
label: 'FiveRP',
data: [<?php foreach ($data0 as $key => $value) {
echo "'$value->player_count',";
} ?>],
backgroundColor: "rgba(75,192,192,0.4)",
fill: false,
lineTension: 0.1,
borderColor: "rgba(75,192,192,1)",
borderCapStyle: 'butt'
}, {
label: 'GTALife',
data: [<?php foreach ($data1 as $key => $value) {
echo "'$value->player_count',";
} ?>],
backgroundColor: "rgba(148,0,211,0.4)",
fill: false,
lineTension: 0.1,
borderColor: "rgba(148,0,211,1)",
borderCapStyle: 'butt'
}, {
label: 'GermanV',
data: [<?php foreach ($data2 as $key => $value) {
echo "'$value->player_count',";
} ?>],
backgroundColor: "rgba(255,165,0,0.4)",
fill: false,
lineTension: 0.1,
borderColor: "rgba(255,165,0,1)",
borderCapStyle: 'butt'
}]
},
options: {
responsive: false,
}
});
