@ashu-sharma,

In the link that you have shared, there are couple of issues because of which image is not being shown. Please find them addressed below.

1. Image for the 1st datapoint is not shown as markerImageUrl is not passed to it. Passing markerImageUrl works fine.
{"y":"","label":125, "markerImageUrl":"https:\/\/soundoflife.in\/audiology\/images\/less-than.png"}

2. Images are not being shown in 2nd chart as imageUrl property is being stored in 2nd dataseries of the chart but while passing it as src, you are trying to read it from 1st dataseries. Reading it from 2nd dataseries works fine in this case. Please find the code-snippet below.

function addMarkerImages1(chart1) {
  for (var i = 0; i < chart1.data[1].dataPoints.length; i++) {
    Markers.push($("<img>").attr("src",chart1.data[1].dataPoints[i].ImageUrl)
      .css("display", "none")
      .css("height", 20)
      .css("width", 20)
    
      .appendTo($("#chartContainer1>.canvasjs-chart-container"))
    );
    positionMarkerImage1(Markers[i], i);
  }
}

If you are still facing issue, kindly create JSFiddle reproducing the issue you are facing and share it with us so that we can look into the code, understand the scenario better and help you out.

Considering this as duplicate of markerimage, hence closing the same.

@agaur,

Label are shown at a value which is multiple of interval. To show label at the bottom of y-axis, you can add a stripline & set it’s label-placement to outside. Below is the code snippet showing the same.

var axisY = chart.axisY;
axisY.addTo("stripLines", {
  value: axisY.viewportMinimum,
  label: axisY.viewportMinimum,
  labelPlacement: "outside",
  labelFontColor: axisY.labelFontColor,
  color: axisY.tickColor,
  labelBackgroundColor: chart.backgroundColor,
  thickness: 0
});

Please take a look at this JSFiddle for complete code.

@wellhys,

When x-values are not passed, it takes numeric values 0,1,2,3,… In case of numeric axis, intervalType will be number. To set 12 hours interval, you will have to use date-time axis with interval: 12, intervalType:"hours". Else if you like to go with numeric-data, you can set the interval: 12 if it’s hourly data.

@zenoechozz,

You can pass dataPoints to the chart as [{x: 1, y: 10}, {x: 2, y: 20},...}. Please refer this documentation page for more information on the data format accepted by CanvasJS.

Also please refer to the code available in the Gallery page for an example on reading data for multiple charts from single JSON file.

@wellhys,

React samples are working fine. Please follow the below steps to add CanvasJS StockChart to your app.
1. Save canvasjs.stock.react.js and canvasjs.stock.min.js within source-folder of your React application ( src or src/assets or src/lib )
2. Import the StockChart component to your app.
import CanvasJSReact from './canvasjs.stock.react';
Please refer to this documentation page for step-to-step tutorial on integrating CanvasJS in react app. Also checkout this Stackblitz demo for working code.

If you are still facing issue, kindly share the sample project with us over Google-Drive or Onedrive so that we can look into the code, understand the scenario better and help you out.

@wellhys,

StockCharts comes with synchronizing tooltip & crosshair as an inbuild feature. You can use our react-component to add StockCharts to your react app. Please refer to React Gallery Section for examples on React StockCharts. Also refer to this demo page for an example on adding multiple charts with date-time axis in React StockChart.

@gaurav-sharma6,

You can zoom individual chart by rotating mouse-wheel by binding wheel event to the container of individual charts of StockChart. Please find the code snippet for the same below.

function addWheelZoom(stockChart) {
  stockChart.charts[0].container.addEventListener("wheel", function(e){
    e.preventDefault();

    var slider = stockChart.navigator.slider;
    var sliderMinimum = slider.get("minimum"),
        sliderMaximum = slider.get("maximum");
    
    var interval = (slider.get("maximum") - slider.get("minimum"))/50; // change interval based on the range of slider
    var newMin, newMax;

    if (e.deltaY < 0) {
      newMin = sliderMinimum + interval;
      newMax = sliderMaximum - interval;
    }
    else if (e.deltaY > 0) {
      newMin = sliderMinimum - interval;
      newMax = sliderMaximum + interval;
    }

    if(newMax < stockChart.navigator.axisX[0].get("maximum") || newMin > stockChart.navigator.axisX[0].get("minimum")) { 
      stockChart.navigator.slider.set("minimum", newMin, false);
      stockChart.navigator.slider.set("maximum", newMax);
    }
  });
}

Please take a look at this JSFiddle for a working example on zooming StockChart using mouse-wheel.

Considering this thread as duplicate of zoomin/zoomout on wheel movement. Hence Closing the same.

@hmike0878,

Datapoints supports both numeric and date-time for x-values. You can either pass date-time values as date object or timestamp. If you are passing x-values as timestamp, you will have to set xValueType to ‘dateTime’ – xValueType: "dateTime". Please take a look at this documentation page for tutorial on using date-time values in chart along with examples that you can try out or download from the editor.

@jeonkook,

The issue seems to be happening as you are returning the value as such in labelFormatter without formatting it. You can format the number to fix the number of decimal values by using formatNumber method.
CanvasJS.formatNumber(e.value, "#,##0.##")
Please take a look at this updated JSFiddle for working sample.

Also, please refer to valueFormatString which lets you format the value that appears in axis / parameter that you pass in formatNumber method.

@frawolf,

We observed that the react wrapper that you are using is not official wrapper but a 3rd-party one. Using official wrapper seems to be working fine. You can download CanvasJS charting library along with wrapper from our download page and refer to our documentation for step-to-step tutorial on integration. Please download the working sample (official react wrapper) from here.

@kinokatsu,

Adding dummy series to secondary x-axis also works in your case. Glad that you were able to fulfill your requirements :)
