Tooltip

[heinemannj]

Is there any possibility to add a free configurable Tooltip (HTML DIV element) when moving the mouse over data points? Google chart which I'm using right now has a lot of other limitations.

Examples and goals:

I've found the following workarround:

const jsgraphStyle = {
	id: 'chart0',
	width: 1200,
	height: 600,
	XAxisForceMin: 100,
	XAxisForceMax: 1300,
	YAxisForceMin: 0,
	YAxisForceMax: 100,
	backgroundImage: null
}

graph.tracking( {
	mode: 'individual',
	textMethod: function(output) {
		let txt = '';
		let i = 0;
		let documentClassId = document.getElementById(jsgraphStyle.id).getElementsByClassName('trackingLegend')[1];

		for (i in output) {
			if (!output[i].closestPoint) {
				continue;
			}
			if (i >= 1) {
				txt += '<br>';
			}
			txt += `${output[i].serie.getName()}: <br>
				${jsgraph.axes.x.label}: 
				${output[i].serie.getXAxis().valueToHtml(output[i].closestPoint.xClosest, true, true, 0)} 
				${jsgraph.axes.x.unit}`;
			txt += `<br> ${jsgraph.axes.y.label}: 
				${output[i].serie.getYAxis().valueToHtml(output[i].closestPoint.yClosest, true, true, 2)} 
				${jsgraph.axes.y.unit}<br>`;
		}
		documentClassId.style.backgroundColor = `rgb(${255 - output[i].closestPoint.xClosest * 0.3}, ${255 - output[i].closestPoint.xClosest * 0.3}, ${255 - output[i].closestPoint.xClosest * 0.3})`;

		return txt;
	},
	series: [ jsgraph.series[0].name ],
	legend: true,
	legendType: 'common',
	serieOptions: {
		withinPx: 10
	},
} );

However - A marker on the graph is missing with above:

Same here, I think d8c805d should fix this issue

[NPellet]

Which is now published as v2.4.13 on npm.

Again, waiting for confirmation before closing

Tested again with v2.4.13 - Not working as expected.

Above graph has not changed.

You need to use dist/jsGraph.js

I'm phasing out the other versions
