@friday096,

You can create similar graph that you are referring in the link shared above by creating a dynamic chart and by setting labelAutoFit to false as well as setting y-axis maximum. Please take a look at this StackBlitz project for an example on the same in React.

@ram-chella,

To avoid clipping of axis labels in navigator, you can set labelAngle to -1 in the navigator x-axis. Please find the below code-snippet for the same.
navigator: {
axisX: {
labelAngle: -1
}
}

@friday096,

Sorry, it’s not possible to animate the chart every 5 seconds as the chart animates only on the first render, as of now.

@scroteau,

rangeChanging event is fired when the range of the chart is about to be changed i.e. just before rendering of the chart with updated viewport values. While rangeChanged event is fired after the chart is rendered with updated viewport values. With help of dynamicUpdate in StockChart, you can control when to fire rangeChanged and rangeChanging events. If dynamicUpdate is set to true, then range of chart will be updated at every movement of handle and hence rangeChanging and rangeChanged will be fired on updated viewport values. When dynamicUpdate is set to false, the range of the chart will be not updated at every movement of handle but rather will be updated when you release the handle. So rangeChanged and rangeChanging will be fired only on release of handle.

@scroteau,

You can update the dataPoints using set method like stockChart.charts[0].data[0].set("dataPoints", subsetDataPoints)or update the stockchart options like stockChart.options.charts[0].data[0].dataPoints = subsetDataPoints. Please take a look at this updated JSFiddle for sample code.

@scroteau,

rangeChanging and rangeChanged are two different type of event handler which are fired before and after range is changed respectively. rangeChanging can be used to change chart options without any need to call render method to update the options in rangeChanging event handler. But in case of rangeChanged event, you need to call the render method again in order to reflect the change in chart options in the rangeChanged event handler. Please take a look at this JSFiddle for an example demonstrating the sequence in which rangeChanging and rangeChanged event handler is fired.

Furthermore, the “rangeChanged” event.type would seem to be over firing. I would have expected the “rangeChanging” event to fire during “onmousemove” as the user is dragging the slider and then the “rangeChanged” event.type would fire “onmouseup” as the user releases the slider. This would allow us to avoid unnecessary updates as the user is selecting their date range or update immediately depending on which event.type is fired.

You can set dynamicUpdate property of navigator to false to fire rangeChanged or rangeChanging event on mouseup in order to stop unneccessary updates while changing the range on mousemove. Please take a look at this updated JSFiddle for an example on the same.

@coolon,

Glad that you figured it out. You can use connectNullData to connect adjacent non-null data with a straight line.

@coolon,

Can you kindly create JSFiddle reproducing the issue you are facing & share it with us so that we can look into the code / chart-options being used, understand the scenario better and help you out?

@sprawl,

Please take a look at this documentation page for step by step instruction for rendering multiple chart in a single page.

If you are still facing the issue, kindly create a sample project reproducing the issue you are facing and share it with us over Google-Drive or OneDrive so that we can look into the code, run it locally at our end to understand the scenario better and help you out.

@keval-panchal,

You can create a custom DOM for tooltip and show it on click of the dataPoint as shown in the code snippet below.

function showToolTipOnClick(e) {
    isDataPointClicked = true;
    if(dataPointShown !== e.dataPoint) {
      clicked = true;
      dataPointShown = e.dataPoint;
    } else {
      clicked = !clicked;	
    }

    if(customToolTipDOM === null) {
      customToolTipDOM = document.createElement("div");
      e.chart.container.appendChild(customToolTipDOM);
      customToolTipDOM.style.display = "none";
      customToolTipDOM.style.position = "absolute";
      customToolTipDOM.style.background = "#fff";
      customToolTipDOM.style.border = "1px solid #dedede";
      customToolTipDOM.style.borderRadius = "4px";
      customToolTipDOM.style.padding = "8px";
      customToolTipDOM.style.top = "0px";
      customToolTipDOM.style.left = "0px";
    }

    if(clicked) {
      left = Math.round(e.chart.axisX[0].convertValueToPixel(e.dataPoint.x)) + 30;
      customToolTipDOM.style.left =   "0px";
      customToolTipDOM.style.top =  Math.round(e.chart.axisY[0].convertValueToPixel(e.dataPoint.y)) + "px";
      customToolTipDOM.innerHTML = e.dataPoint.toolTipData;    
      customToolTipDOM.style.display = "block";
      

      if(left + customToolTipDOM.offsetWidth + 30 > e.chart.container.offsetWidth) {
        left = left - customToolTipDOM.offsetWidth - 30;
      }
      customToolTipDOM.style.left =  left + "px";
      
    } else {
      customToolTipDOM.style.display = "none";
    }

  }
  chart.container.addEventListener("click", function() {
    if(!isDataPointClicked && customToolTipDOM) {
      customToolTipDOM.style.display = "none";
      clicked = false;
    }
    isDataPointClicked = false;
  });

Also, check out this updated JSFiddle for showing toolTip on click of the dataPoint.

@sprawl,

You can convert your laptime format string to milliseconds and pass it as y-values in the dataSeries. For axis labels, you format the milliseconds passed to your desired format (minutes:seconds:milliseconds) using labelFormatter & contentFormatter for tooltip. Please find the code-snippet below.

var dps = [
    { x: 1, y: "1:57:420" },
    { x: 2, y: "1:57:340" }, 
    { x: 3, y: "1:56:587" }, 
    { x: 4, y: "1:56:225" }, 
    { x: 5, y: "2:0:110" }, 
    { x: 6, y: "2:2:102" }
  ]

  dps.forEach(dp => {
    var splitString = dp.y.split(":");
    dp.y = parseInt(splitString[0]) * 60 * 1000 + parseInt(splitString[1]) * 1000 + parseInt(splitString[2]);
  })

  function formatMilliSeconds(val) {
    var minutes = parseInt(val / (60 * 1000));
    var seconds = parseInt(val % (60 * 1000) / 1000);
    var ms = parseInt(val % (60 * 1000) % 1000);
    return minutes + ":" + seconds + ":" + ms;
  }

  var chart = new CanvasJS.Chart("chartContainer", {
    .
    .
    .
    axisY: {
      labelFormatter: function(e) {
        return formatMilliSeconds(e.value)
      }
    },
    toolTip: {
    	contentFormatter: function(e) {
      	toolTipContent = "";
      	e.entries.forEach( (entry) => {
        	toolTipContent += "x -> " + entry.dataPoint.x + "<br/>y -> " + formatMilliSeconds(entry.dataPoint.y) + "<br/>"
        })
      	return toolTipContent;
      }
    },
    .
    .
    .
  });
