@aunni,

As of now, the tooltip is shown based on nearest x-values irrespective of y-values. In order to show tooltip based on y-values in a vertical line chart, you can create line chart and rotate it as shown in this JSFiddle.

@mm,

[UPDATE]

We have just released v3.12.5 with the above bug fix. Please refer the release blog for more information. Do download the latest version from our download page and let us know your feedback.

Thanks for reporting the use-case. It seems like there is an issue with axis labeling when scalebreak is used along with labelAngle and we will fix it in the future releases. Meanwhile, setting labelMaxWidth seems to fix the issue in this scenario. Please take a look at this updated JSFiddle in which labelMaxWidth is set to 100.

Greg,

We tried creating chart with the sample JSON used by you and it seems to be working fine. Please take a look at the screenshot below where date in tooltip is shown as per the JSON data i.e. for 1st Jan 2019, closing value as 130.53.

Also, check out this updated JSFiddle for the same.

@greg-aharonian,

JavaScript dates may display an incorrect day when passed in ISO format (YYYY-MM-DD), depending on the user’s time zone. According to MDN, date-only formats are interpreted as UTC time, and date-time formats are interpreted as local time when the time zone offset is absent. To avoid this problem, you can use date-time format or use a different date format along with time-zone. Please take a look at this JSFiddle for an example on the same.

Also, refer to this Stack Overflow thread for more information.

@maksuda,

CanvasJS is a JavaScript Charting Library and provides API to create & customize charts in the applications. With the help of API, you can build interactive dashboard. Please take a look at these dashboard samples built using CanvasJS.

@klauskobald,

CanvasJS is a client-side library that requires browser environment and APIs to run. You should prevent running CanvasJS in the server environment. To do so in Nuxt app, you can use .client suffix to your component containing CanvasJS Chart. Please checkout this StackBlitz example for an example on integrating CanvasJS Charts in Nuxt app.

Also, check out this documentation page of nuxt to know more about client side component.

@dbrtechnopharma,

In this example, we are reading data from /static/btc-usd-weekly-2021.json file. In your case, you can store the Nifty 200 data in a JSON format and pass it as datapoints to the chart.

@jtr,

Please take a look at this Gallery Page for an example on rendering chart with data from JSON in PHP. If you are still facing issue, kindly create a sample project reproducing the issue you are facing & share it with us so that we can look into the code, understand the scenario better and help you out.

@nydia,

You can use rangeChanged event to get to know the datapoint with maximum value within viewport on zooming/panning. Please take a look at this JSFiddle for an example on showing maximum datapoint within viewport using stripline.

@joshuasosa,

You can show axis labels in exponential form with the help of unicode characters as mentioned in this thread. Please take a look at this JSFiddle for an example.

@harishv,

You can create a websocket service in Angular app which establishes connection with your C-program and receives data. The received data should be parsed to the format accepted by CanvasJS to update the chart. Please check the code-snippet below that shows how to parse the data received from the websocket.

.
ngOnInit(): void {
  this.websocketService.connect();
  this.websocketService.messageReceived.subscribe((message: string) => {
    // message passed from the socket is in format { "value": 10 }. Parse to dataPoint format as per value returned from the socket service.
    let data = JSON.parse(message);
    this.dataPoints.push({
      y: data.value
    });
    this.chart.render();
  })
}
.

You can download the working sample from here. Also, refer to this article for more information on creating websocket service in Angular.
