Nirmalya,

Axis-X does not start from 0 (zero) because of the auto-calculated axis minimum. However, it is possible to begin Axis-X from 0 by setting axis minimum to 0 and resetting it by setting it to null while updating the chart. Please take a look at the code snippet below for the same.

var chart = new CanvasJS.Chart("chartContainer",{
  title :{
    text: "Live Data"
  },
  exportEnabled: true,
  axisX: {
    title: "Axis X Title",
    minimum: 0
  },
  axisY: {
    title: "Units"
  },
  data: [{
    type: "line",
    dataPoints : dps
  }]
});

chart.render();
var xVal = dps.length + 1;
var yVal = 15;
var updateInterval = 10000;
var updateChart = function () {
  chart.options.axisX.minimum = null;
  yVal = yVal + Math.round(5 + Math.random() *(-5-5));
  dps.push({x: xVal,y: yVal});

  xVal++;
  if (dps.length > 10 )
  {
    dps.shift();
  }

  chart.render();
};

setInterval(function(){updateChart()}, updateInterval);

Also, have a look at this JSFiddle for complete working code.

@aksangwan,

It is possible to calculate the range between the two selected dataPoints (select by clicking on dataPoints) with the help of click event.
Please take a look at this jsfiddle.

@martin,

It is possible to make the marker visible only when condition is met. For which, you need to set markerSize to zero at dataSeries level and set the markerSize to a desired value for the dataPoint that satisfies the condition. Please take a look at this jsfiddle.

@akshay30498,

You can use x-values along with labels to achieve this. You can group same labels by having same x-values to them. Please take a look at this jsfiddle.

@faulduff,

You can display the x axis labels from data retrieved from CSV file by pushing the dataPoints with labels along with y-values to chart. Please take a look at this jsfiddle.
If this doesn’t solve your requirement, please share a jsfiddle, so that we can understand your requirement better and help you out.
