@ashu-sharma,
You can have a condition check before pushing image in addMarkerImages1 method to avoid adding image when datapoint y-value is empty string. Please find the code-snippet below.
function addMarkerImages1(chart1) {
for (var i = 0; i < chart1.data[1].dataPoints.length; i++) {
if(chart1.data[1].dataPoints[i].y != ""){
Markers.push({image: $("<img>").attr("src",chart1.data[1].dataPoints[i].ImageUrl)
.css("display", "none")
.css("height", 20)
.css("width", 20)
.appendTo($("#chartContainer1>.canvasjs-chart-container"))
, dataPointIndex: i});
}
}
for(var i = 0; i < Markers.length; i++)
positionMarkerImage1(Markers[i].image, Markers[i].dataPointIndex);
}
Please take a look at this JSFiddle for complete code.
If you are still facing issue, kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can run the code at our end, debug to understand the scenario & help you resolve.
