Jason,

v1.7.0 doesn’t have this feature. Please upgrade to use this feature.

Monirul,

We observed that the characters you have mentioned are supported and are working fine. Please check this jsfiddle. You can also use Unicode to represent the same.

Sandonet,

You seem to be passing wrong parameters to getJSON. Replacing
$.getJSON("test.json" + (dataPoints.length + 1) + (dataPoints[dataPoints.length - 1].y) + function(data)
with
$.getJSON("test.json", function(data) { in updateChart function should work fine. Please find the working code below.

function updateChart() {
	$.getJSON("test.json", function(data) {
		$.each(data, function(key, value) {
			dataPoints.push({
			x: parseInt(value[0]),
			y: parseInt(value[1]),
			z: parseInt(value[2])
			});
		});
		chart.render();
		setTimeout(function(){updateChart()}, 1000);
	});
}

Eesger,

Thanks for the posting the solution. It would help others who will be searching for the similar.

Eesger,

As of now we don’t have this feature. But you can work around by setting fillOpacity to 0.7 or 0.8 to make gridlines visible through dataPoints. Check this jsfiddle.

Another option is to place stripLines with showOnTop set to true, so that lines are shown on top of data. Check this jsfiddle.

Navinder,

As of now we don’t have 3D support in charts

Chandru,

Please check this jsfiddle.

Prasanth,

You can use JavaScript eval() function to evaluate an expression. According to user input expression generate dataPoints and render chart. Here is an example.

[Vishwas R]

Prasanth,

You can store all generated dataPoints, according to equation, in an array and assign it to chart dataPoints. Here is an example.

Eshwar,

toolTip, click events are applied even to dataPoint with zero y-value. Here is the updated fiddle.

Jenilkanani,

If y-value is zero, when you mouse-hover the axisX line at the corresponding x-value toolTip will be shown. Check the screenshot below. If the y-value (zero) is not present in first dataSeries, you can set toolTip.shared to true to show the zero value in toolTip.

If this doesn’t solve your requirement, kindly create a jsfiddle, so that we can look into your requirement properly and help you out.

Wazabe,

You can use stripLines to achieve this. Check this example.
