You can check demo at https://codepen.io/ittus/pen/MGQaNY
To make tooltips always display, you can add
Chart.pluginService.register({
beforeRender: function(chart) {
if (chart.config.options.showAllTooltips) {
chart.pluginTooltips = [];
chart.config.data.datasets.forEach(function(dataset, i) {
chart.getDatasetMeta(i).data.forEach(function(sector, j) {
chart.pluginTooltips.push(new Chart.Tooltip({
_chart: chart.chart,
_chartInstance: chart,
_data: chart.data,
_options: chart.options.tooltips,
_active: [sector]
}, chart));
});
}); // turn off normal tooltips
chart.options.tooltips.enabled = false;
}
},
afterDraw: function(chart, easing) {
if (chart.config.options.showAllTooltips) { // we don't want the permanent tooltips to animate, so don't do anything till the animation runs atleast once
if (!chart.allTooltipsOnce) {
if (easing !== 1) return;
chart.allTooltipsOnce = true;
}
chart.options.tooltips.enabled = true;
Chart.helpers.each(chart.pluginTooltips, function(tooltip) {
tooltip.initialize();
tooltip.update(); // we don't actually need this since we are not animating tooltips
tooltip.pivot();
tooltip.transition(easing).draw();
});
chart.options.tooltips.enabled = false;
}
}
});
then pass showAllTooltips: true
into options
