How to Create synchronized High chart with different no of series per chart

I want to create a synchronized High chart with two charts and the 1st chart will have one series and 2nd chart will have 2 series.
this link contains the sync chart with two series each chart, but when I reduced data to my required condition crosshair did not work properly.
data for chart.
var activity = {
"xData": [1, 1056, 2161, 3215, 4267],
"datasets": [{
"name": "Chart 1 series 1",
"data": [0, 10, 20, 30, 20],
"unit": "ms",
"type": "line",
"valueDecimals": 1
}, {
"name": "Chart 1 series 2",
"data": [23, 84, 22, 5, 75],
"unit": "ms",
"type": "line",
"valueDecimals": 1
}, {
"name": "Chart 2 series 1",
"data": [0, 10, 20, 30, 20],
"unit": "%",
"type": "line",
"valueDecimals": 1
}]

You are going from 2 series on each chart to 2 series on the 1st chart and 1 series on the 2nd chart, so you will be getting an error while trying your updated activity data. You need to add a conditional check like this (comments in uppercase):
/*

amcharts' stockChart mouse move listener

I'm trying to add a listener to amCharts' stockChart but can't find where.
According to the docs of chartCursor you can set changed event on chartCursor however chartCursor does not exist on stockChart, only regular charts according to the docs of the StockChart.
As far as I can see the only semi-relevant settings is chartCursorSettings but it does not allow setting any listeners.
How can I catch mouse move/changed event over amCharts' amStockChart ?

The changed event can be caught at the panel level:
var chart = AmCharts.makeChart("chartdiv", {
// ...
"panels": [{
// ...
"listeners": [{
"event": "changed",
"method": function(e) {
console.log('changed event fired')
}
}],
}],
// ...
});
Demo below:
var chart = AmCharts.makeChart("chartdiv", {
"type": "stock",
"theme": "light",
"categoryAxesSettings": {
"minPeriod": "mm"
},
"dataSets": [{
"fieldMappings": [{
"fromField": "value",
"toField": "value"
}],
"dataProvider": generateChartData(),
"categoryField": "date"
}],
"panels": [{
"stockGraphs": [{
"valueField": "value",
"type": "smoothedLine"
}],
"listeners": [{
"event": "changed",
"method": function(e) {
console.log('changed event fired')
}
}],
}],
"chartCursorSettings": {
"valueBalloonsEnabled": true
}
});
function generateChartData() {
var chartData = [];
var firstDate = new Date( 2012, 0, 1 );
firstDate.setDate( firstDate.getDate() - 1000 );
firstDate.setHours( 0, 0, 0, 0 );
for ( var i = 0; i < 1000; i++ ) {
var newDate = new Date( firstDate );
newDate.setHours( 0, i, 0, 0 );
var a = Math.round( Math.random() * ( 40 + i ) ) + 100 + i;
chartData.push( {
date: newDate,
value: a
} );
}
return chartData;
}

"datasets": [{
"name": "Speed",
"data": [10,20,30,40,50,60,70,80,90,100],
"unit": "km/h",
"type": "line",
"valueDecimals": 1
}, {
"name": "Elevation",
"data": [10,20,30,40,50,60,70,80,90,100],
"unit": "m",
"type": "area",
"valueDecimals": 0
}, {

"unit": "l",
"type": "area",
"valueDecimals": 0
}]
}
Anyway, the most preferable way is to use getJson method:
$.getJSON( "test.json", function( data ) {
var items = [];
$.each( data, function( key, val ) {
... process data
});
...
});

How to refresh kendo Graph using SignalR notfication

I want to refresh kendo graph once I am getting notification from SignalR.
Here is my code
function CreateChart()
{
$("#chart").kendoChart({
title: {
position: "bottom",
text: "Import Log"
},
legend: {
position: "bottom"
},
chartArea: {
background: ""
},
seriesDefaults: {
labels: {
visible: true,
background: "transparent",
template: "#= dataItem.CategoryField #: \n #= dataItem.Percentage#%"
}
},
dataSource: [{ "CategoryField": "Success", "Percentage": 0 }, { "CategoryField": "Error", "Percentage": 0 }, { "CategoryField": "Info", "Percentage": 0 }, { "CategoryField": "Total", "Percentage": 100}],
series: [{
type: "donut",
field: "Percentage",
categoryField: "CategoryField"
}],
seriesColors: ["Green", "red", "#FFD54C", "#EEEEEE"]
});
}
updateProgress = function (successPct, errPct, infoPct)
{
var selectedChart = $("#chart").data("kendoChart");
var ds = selectedChart.dataSource;
var progress = ds.at(0);
var error = ds.at(1);
var info = ds.at(2);
var total = ds.at(3);
progress.set("Percentage", data.SuccessPercentage);
error.set("Percentage", data.ErrorPercentage);
info.set("Percentage", data.InfoPercentage);
total.set("Percentage", 100 - data.SuccessPercentage - data.ErrorPercentage - data.InfoPercentage);
selectedChart.refresh();
}
$(document).ready(function () {
CreateChart();
var importNotifier = $.connection.runImport;
importNotifier.client.sendMessage = function (data) {
$("#chart").append(data.SuccessPercentage + " " + data.ErrorPercentage + " " + data.InfoPercentage)
updateProgress(data.SuccessPercentage, data.ErrorPercentage, data.InfoPercentage);
};
$.connection.hub.start().done(function () {
importNotifier.server.import();
});
});
Here I created method Update Progress to update chart. But chart is not refreshed until entire server side processing is completed. Once All server side processing is completed then only chart update works. I want to update my chart only when I get any notification from SignalR.

Flot Chart : Adding Checkbox's to Toggle Chart Series

After setting up my first chart I'm looking to add check-boxs to toggle which series are selected.
Flot provides an example here : http://www.flotcharts.org/flot/examples/series-toggle/
Now when i tried to replicate this I'm getting error: 'datasets' is undefined could anyone explain why??
Also bonus points if anyone can tell my why the legend still display's inside the graph?
Chart Looks like :
View Code :
<div class="legend-container"></div>
<div class="graph-container">
<div id="placeholder" class="graph-placeholder"></div>
</div>
<p id="choices"></p>
Chart Code:
$(document).ready(function fetchData() {
function onDataReceived(series)
{
console.log('recieved data now parsing the data');
var currentdata = $.parseJSON(series);
//Testing
console.log(currentdata);
console.log("series sub-arrays");
console.log(currentdata[0]);
console.log(currentdata[1]);
console.log(currentdata[2]);
var datasets = [
{
label: "Current_Out",
data: currentdata[0],
yaxis: 2,
color: '#00C932',
points: { fillColor: "#00C932", show: true },
lines: { show: true }
}, {
label: "Temperature",
data: currentdata[1],
yaxis: 1,
color: "#0062FF",
points: { fillColor: "#0062FF", show: true },
lines: {show:true }
}]
var options = {
legend: {
show: true,
placement: 'outsideGrid',
container: $("#legend-container")
},
lines: {
show: true,
fill: false,
},
axisLabels: {
show: true
},
xaxes: [{
mode: "time",
timeformat: "%H:%M:%S",
axisLabel:'Date',
axisLabelUseCanvas: false,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial, Helvetica, Tahoma, sans-serif',
axisLabelPadding: 5
}],
yaxes: [{
position: "left",
axisLabel:'Celcius',
axisLabelUseCanvas: true,
axisLabelFontSizePixels: 12,
axisLabelFontFamily: 'Verdana, Arial, Helvetica, Tahoma, sans-serif',
axisLabelPadding: 5
}, {
position: "right",
axisLabel: 'mA'
}],
grid: {
hoverable: true,
clickable: true,
borderWidth: 1
},
legend: {
labelBoxBorderColor: "none",
position: "right"
},
points: {
show: true,
fillColor: "#000000"
}
};
$.plot($("#placeholder"), datasets, options);
}
$.ajax({
url: '/Ajax/GetGraphData',
type: "GET",
dataType: "json",
success: onDataReceived,
failure: function() {
console.log('Fail!');
}
});
Jquery for Checkbox's
// insert checkboxes
var choiceContainer = $("#choices");
$.each(datasets, function (key, val) {
choiceContainer.append('<br/><input type="checkbox" name="' + key +
'" checked="checked" id="id' + key + '">' +
'<label for="id' + key + '">'
+ val.label + '</label>');
});
choiceContainer.find("input").click(plotAccordingToChoices);
function plotAccordingToChoices() {
var data = [];
choiceContainer.find("input:checked").each(function () {
var key = $(this).attr("name");
if (key && datasets[key])
data.push(datasets[key]);
});
if (data.length > 0)
$.plot($("#placeholder"), data, {
yaxis: { min: 0 },
xaxis: { tickDecimals: 0 }
});
}
plotAccordingToChoices();

Scoping issue. var datasets is local to the onDataReceived function. It is not accessible outside that function. Initing it to null in the $(document).ready( handler should make it accessible to everything in that scope.
As for your second question, you need to show us the CSS attached to those divs. I'm guessing your graph-container is absoluting positioned. Also, in your options, you have two different configurations for legend. Delete the second one.
