Hey @flyingpath,
Full credit goes to @lschneiderman who came up with the solution in the Chartjs repo. chartjs/Chart.js#1861
Simply use the following options:
const options = {
showAllTooltips: true
};
and put the following in your componentWillMount
componentWillMount() {
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;
}
}
});
}
I just verified its working with this code. Let me know if you have anymore troubles!

It didn't work for me.
I got the following error.
TypeError: Cannot read property 'register' of undefined Categories.componentWillMount src/categories.js:1593 1590 | } 1591 | 1592 | componentWillMount() { > 1593 | Chart.pluginService.register({ 1594 | beforeRender: function (chart) { 1595 | if (chart.config.options.showAllTooltips) { 1596 | chart.pluginTooltips = [];

Yes! Any simple way to do that on react chartjs?
Or can only use it on charjs ?
