JohnSnowGum,

Please refer this documentation page for step-to-step tutorial on rendering chart with data from JSON source.

Please take a look into this JSFiddle for an example on chart with date here the data is served from an external JSON source.

@gussmarcaro,

Thanks for reporting this issue. It happens when you try to format tooltip content using {#percent%} for the dataPoints that has y value 0 and tooltip is shared. We will reconsider this issue and fix it in our future releases.

JohnSnowGum,

You can calculate the frequency the date-occurrences in the data & build a set of datapoints. Please refer the code-snippet below.

function calculateFrequency(dateArray) {
  dateArray.sort();
  var currentXValue = null;
  var count = 0;

  for (var i = 0; i < dateArray.length; i++) {
    if (dateArray[i] != currentXValue) {
      if (count > 0)
        dps.push({x: new Date(currentXValue), y: count});
      currentXValue = dateArray[i];
      count = 1;
    } else {
      count++;
    }
  }
  if (count > 0)
    dps.push({x: new Date(currentXValue), y: count});
}

Please take a look at this JSFiddle for complete code. This example reads data from an array instead of database.

@taszta,

Please take a look at this sample project for integrating CanvasJS in Spring MVC web-project that uses Thymeleaf template engine as view layer.

@raktimprat,

Please take a look at this jsfiddle. Here, the chart gets dynamically updated according to the external JSON source provided. Similarly, you can use a different data source that updates dynamically to plot a dynamic chart.

@adirgapalit,

Trial Version is for evaluation purposes for up to 30 days. To use charts without ‘Trial Version’ and ‘CanvasJS’ Credit Link you will need to have a Commercial Version of CanvasJS. Please contact sales@canvasjs.com for sales related queries.

@ethicalsector,

Padding is considered at the time of rendering and it varies from element to element. Padding applied to the elements are dependent on each other, hence it is not possible to control padding for one element externally and expect the other elements to be aligned properly.

We will reconsider this behavior in our future releases.

@mhdajmalik,

Zoom in and Zoom out is not working

Please take a look at this jsfiddle. Setting appropriate minimum and maximum values should work fine.

Line Marker:- I don’t want the whole line, I need a line like what we marked in image 1 (see image-1, marked as option 1)

This feature is not available as of now. However, you can place stripLines at the values you need, as shown in this jsfiddle.

Can I handle zoom in and zoom out by an event (see image-1, marked as option 2)

This feature is not available as of now. However, you can achieve this by changing viewportMinimum and viewportMaximum every time zoom in / zoom out is clicked.
