[arj]

Hi Team,

I am trying to render multiple series and there is a case when we have multiple series stacked on top of each other the chart show the second series whereas tooltip and marker shown for the series upon point hover?

window.onload = function () {

var chart = new CanvasJS.Chart(“chartContainer”, {
title: {
text: “House Median Price”
},
axisX: {
valueFormatString: “MMM YYYY”
},
axisY2: {
title: “Median List Price”,
prefix: “$”,
suffix: “K”
},
toolTip: {
shared: false
},
legend: {
cursor: “pointer”,
verticalAlign: “top”,
horizontalAlign: “center”,
dockInsidePlotArea: true,
itemclick: toogleDataSeries
},
data: [{

Tooltip & marker shown from the first series,

[Ananya]

@arj,

When datapoints of different dataseries overlap, tooltip is shown for the first series to make the user aware of the hidden dataseries.

If you want to show the tooltip for all the available dataseries, you can set toolTip shared property to true.

Is there a way i can call up mouse event when hovering within the chart like when in case of shared tooltip.

[Ananya]

@arj,

You can bind mouse events to the chart container, and show the toolTip at the datapoint nearest to the current x-coordinate, by using the toolTip showAtX method. Please take a look at this JSFiddle for an example of the same.

If this is not what you are looking for, could you please brief us more about your usecase, so that we can understand it better and help you out?
