@scompliance,

Datapoint click event is not getting fired as image placed on top of datapoint captures the event. Bypassing pointer-events & toggling display property between “none” and “block” on datapoint click should work fine in this case.

Please take a look at this updated JSFiddle for a working example of the same.

@scompliance,

You can get the axis properties like minimum, maximum, etc. in useEffect hook as show in the code-snippet below.

useEffect(() => {
  chart.axisX[0].addTo('stripLines', {
    startValue: chart.axisX[0].get('minimum'),
    endValue: chart.axisX[0].get('maximum'),
    color: 'rgba(221, 160, 221, 0.1)',
  });
}, []);

You can add stripline as plotarea background once you have access to axis range properties. Please take a look at this Stackblitz for an example of the same.

@scompliance,

Please take a look at this Stackblitz link for an example on adding tooltip to Stripline in React, same as JSFiddle shared earlier.

@scompliance,

Legends for striplines are not available as of now. However, you can add a dummy dataseries to show legend for stripline as shown in this updated JSFiddle.

If you are looking for something else, can you kindly fork the JSFiddle and share it with us so that we understand your scenario better & help you out?

@scompliance,

Showing tooltip to stripline is not available as an inbuilt feature as of now. However, you can show tooltip with few lines of code by adding a div on mouse-move as shown in the code-snippet below.

chart.container.addEventListener("mousemove", function(e) {
  var xPos = e.pageX - this.offsetLeft, 
      yPos = e.pageY - this.offsetTop,
      bounds = stripLine.bounds,
      index = stripLine._index;

  if((bounds.x1 <= xPos && xPos <= bounds.x2) && (bounds.y1 <= yPos && yPos <= bounds.y2)) {
    if(document.getElementById("striplineTooltip" + index)) {
      document.getElementById("striplineTooltip" + index).style.display = "block";
      document.getElementById("striplineTooltip" + index).style.left = xPos + "px";
      document.getElementById("striplineTooltip" + index).style.top = yPos + "px";
    }
    else {
      var tooltip = document.createElement("div");
      tooltip.setAttribute("id", "striplineTooltip" + index);
      tooltip.setAttribute("class", "tooltip");
      tooltip.innerHTML = "<div class='tooltiptext'>" + toolTipContent + "</div>";
      this.appendChild(tooltip);
    }
  }
  else {
    if(document.getElementById("striplineTooltip" + index)) {
      document.getElementById("striplineTooltip" + index).style.display = "none";
    }
  }
});

Please take a look at this JSFiddle for a working example on the same.

@diano4ka,

To ensure axis grids are displayed, you need to pass an empty dataseries & specify the chart type (like “line” or “column”, defaults to “column”) along with grid-options. You need to explicitly pass empty dataseries as axis is not present in chart-types like pie, doughnut, funnel & pyramid. Hence, the axis elements passed in options are not considered when chart-type is unknown – when data is an empty array. Changing data:[] to data:[{}] should work fine in your case. Please take a look at this JSFiddle for an example of the same.

@sujeet,

You are getting this warning because angular-charts package uses CommonJS/AMD modules. You can suppress the warning by adding it to allowedCommonJsDependencies under build options in your angular.json file, as shown below:

"build": {
    "options": {
        "allowedCommonJsDependencies": [
            "@canvasjs/angular-charts"
        ],
        ...
    },
    ...
}

Please refer to this angular documentation for more information.

@scompliance,

Looks like brave is blocking getImageData() function which is used for hit detection. Hide / Unhide Dataseries on Legend click should work fine when you disable “Block Fingerprinting” in Brave Shields. Please refer the below links for more information.

@fatemk,

Re-rendering the chart on resizing the grid should work fine in this case. You can re-render the chart either on resize or resizestop events. Please find the code-snippet below.

grid.on("resizestop", function(resizestop) {
    chart.render();
});

Please take a look at this updated pen for complete code.

Also, you seem to be using third-party CanvasJS React Charts package. We recommend you to use Official CanvasJS React Charts package.

Max Fey,

Adding commonjsOptions: { transformMixedEsModules: true } to the build option of Vite config should fix this issue. Please refer to this Stack Overflow thread for more information about the same. Please take a look at this link for a working sample that’s deployed in vercel and checkout this Github repository for the project.

Max Fey,

We tried deploying a React app with CanvasJS Chart in vercel, it seems to be working fine. Please take a look at this link for a working sample that’s deployed in vercel and checkout this Github repository for the project.

If you are still facing issue, kindly share your project with us over Google-Drive or Onedrive (or in Github) so that we can try deploying it from our side to understand the scenario better and help you out.

@sameer89,

You can import CanvasJS from angular-charts package to add custom colorset as shown in the code-snippet below.

import { CanvasJS } from '@canvasjs/angular-charts';
CanvasJS.addColorSet('customColorSet', ['#4661EE', '#EC5657', '#1BCDD1', '#8FAABB', '#B08BEB', '#3EA0DD', '#F5A52A', '#23BFAA', '#FAA586', '#EB8CC6']);

Please take a look at this Stackblitz for an example of the same.

@kpandey017,

Labels are displayed at regular intervals on the axis. Additionally, to enhance readability and prevent overlapping, the chart omits alternate labels, in some cases. However, if you prefer to display all labels, you can achieve this by setting the interval to 1.

axisX: {
  interval: 1
}

Please take a look at this updated JSFiddle for the working code.

@codetonight,

You can update the chart title dynamically to reflect the name of the selected datapoint upon clicking. Please find the code-snippet below:

click: function(e) {
  e.chart.title.set("text", e.dataPoint.name);
}

Please take a look a this JSFiddle for an example of the same.
