@ray,

Thanks for the suggestion. As of now, this feature is not inline with our current roadmap.

@yueming,

As of now it is not possible to position axisY at the center of the chart. However, you can workaround this by positioning axisY of another chart (without any dataPoint) in the background of current chart. Please check this jsfiddle.

@ray,

You can add color to each dataPoint(i.e. bar or column) by using the color property.

Yes, we do support Apple devices. Can you please tell us more about the issue you are facing along with device, browser, and OS details?

Sorry, it’s not possible to remove the reserved spacing as of now.

@cristiscu,

Sorry, as of now you cannot keep space between the candles and still increase the line thickness.

@aliphpdeveloper,

You can set highlightEnabled to false at dataSeries or dataPoint level to disable highlighting of the dataPoints. And for setting the opacity you can use fillOpacity at dataSeries level or rgba value with color at dataSeries or dataPoint level.

@ray,

This is the intended behavior, the space is being reserved for corresponding dataPoints from different dataSeries. As of now dataPointWidth is available only at chart level.

@daveb222,

It is not possible to clone the entire chart with events using clone method. Please refer this stackoverflow thread for more info. However you can try to render another chart on the modal with same chart options. Please take a look at the code snippet for creating multiple chart with same chart options.

var chartOptions = {
  title: {
    text: "Chart 1"
  },
  data: [{
    type: "spline",
    dataPoints: [
      { x: 10, y: 71 },
      { x: 20, y: 55 },
      { x: 30, y: 50 },
      { x: 40, y: 65 },
      { x: 50, y: 95 },
      { x: 60, y: 68 },
      { x: 70, y: 28 },
      { x: 80, y: 34 },
      { x: 90, y: 14 }
    ]
  }]
};

var chart1 = new CanvasJS.Chart("chartContainer1", chartOptions);
var chart2 = new CanvasJS.Chart("chartContainer2", chartOptions);

Also, check this JSFiddle for complete working code.

@ray,

You can remove the dataPoints with null value as shown in the code snippet below –

for(var i = 0; i < chart.options.data.length; i++) {
  for(var j = 0; j < chart.options.data[i].dataPoints.length; j++) {
    if(chart.options.data[i].dataPoints[j].y === null)
      chart.options.data[i].dataPoints.splice(j, 1);
  }
}

Please take a look at this JSFiddle for a working example.

@harmonickey,

You can use contentFormatter to achieve this. Please refer this jsfiddle.

@nehasingh,

1. Default Markers are automatically disabled when number of dataPoints are more. You can manually override the automatic disabling/enabling of markers by setting markerSize to a value equal to or greater than zero.

{
  .
  .
  data: [{
    markerSize: 10,
    .
    .
  }]
}

Please have a look at this JSFiddle for complete code.

2. You can show the marker image only for current dataPoint by placing the marker Image on top of the last dataPoint every time the chart is updated. Please have a look at this below code snippet for the same.

var updateChart = function () {
  yVal = yVal + Math.round(5 + Math.random() * (-5 - 5));
  dps.push({ x: xVal,y: yVal });
  xVal++;
  if (dps.length > 10)
  {
    dps.shift();
  }
  chart.render();

  // Position image marker over the last/ current dataPoint
  positionMarkerImage(imageMarker, chart.options.data[0].dataPoints.length - 1);
};

function positionMarkerImage(imageMarker, index){ 
  var pixelX = chart.axisX[0].convertValueToPixel(chart.options.data[0].dataPoints[index].x);
  var pixelY = chart.axisY[0].convertValueToPixel(chart.options.data[0].dataPoints[index].y);

  imageMarker.css({"position": "absolute", 
                   "display": "block",
                   "top": pixelY - imageMarker.height()/2,
                   "left": pixelX - imageMarker.width()/2
                  });
}

var updateId = setInterval(function () { updateChart();}, updateInterval);

Please refer to this JSFiddle for complete code on the same.

@aliphpdeveloper,

It seems like you got confused between indexLabelFontStyle and indexLabelFontFamily, please refer the documentation for more info. Also check this updated jsfiddle.

@aliphpdeveloper,

Sorry, we were unable to reproduce the issue regarding change in the size of indexLabel at our end. Can you please create a jsfiddle reproducing the issue and also share browser and OS details along with versions where you are facing this issue.

Regarding your query about placing indexLabels at the bottom, this feature is not available out of the box as of now. However you can follow this workaround.

@aliphpdeveloper,

You can hide the axisX line by setting the lineThickness property to zero. Please check this jsfiddle.
