@reshu,

Please refer to this gallery example to create a dynamic chart in JSP. Also, you can render the chart based on the different data sources such as JSON, XML, CSV and database in JSP.

@sepetar,

From the CanvasJS v1.8 to CanvasJS v2.3.1 we have added many new features to the library because of which the performance may vary by only a few milliseconds.

However, if you can create a JSFiddle reproducing the issue you are facing and share it with us we will look into the code, understand the scenario better and help you out.

@cristi-istrate,

You can achieve the above requirement by setting the maximum and minimum of secondary Axis-Y same as that of the primary Axis-Y using the set method as shown in this JSFiddle.

@artinrezaee,

This behavior is designed such that zooming is limited up to a certain region, so the user doesn’t end up zooming into a blank-region (a region with no dataPoints). To zoom into a certain region, there should be a minimum of 3-4 dataPoints.

In your case, the zoom doesn’t work as there are less than 3-4 dataPoints over the Axis Y but by changing the zoomType to “x” it would work as there are more than 3-4 dataPoints over the Axis X.

@viiartz,

jQuery.getJSON is asynchronous method due to which your chart gets rendered before the array arr_data gets populated. Hence by performing jQuery.getJSON() method inside jQuery.when() method and then calling chart.render() inside the .then() method will work fine in your case as shown in this JSFiddle.

@makasu,

CanvasJS can be integrated with Spring MVC irrespective of the view layer being used in the project. When it comes to the view layer in Spring MVC, it gives you a variety of choices like JSP or template engines like Thymeleaf, Velocity, FreeMarker, etc.

The Spring MVC sample that you can download from our download page uses JSP as view, whereas CanvasJS works smoothly without any issue with any template engines – as CanvasJS is just a JavaScript library, it works fine as the browser supports JavaScript irrespective of any template engine being used.

Here is a sample project of integrating CanvasJS in Spring MVC web-project that uses Thymeleaf template engine as view layer.

@ramtin_vedved,

Can you please let us know which specific component of the chart you would like to be draggable such as dataPoints, chart container(div) etc. so that we can understand your exact use case and help you out with an appropriate solution.

@jfranco30,

CanvasJS just renders charts based on the data that you pass in the chart-options. You can modify your MySQL query to get data based on weeks and pass it to chart to show weekly data.

@afreay,

You can create a drilldown chart by changing the dataPoints of the chart when a dataSeries is clicked. Please take a look at this JSFiddle for an example on the same.

@mdrobinson0124,

We have added this feature in our wishlist but there is no definite timeline yet regarding its release.

@mdrobinson0124,

The occurrence of the above-mentioned scenario is due to the fact that there is no space available on the top of the DataPoints to display the indexLabel. To overcome this you can increase the Axis Y maximum to a certain value so that there is enough space available at the top for the indexLabel to be displayed as shown in this updated JSFiddle.

I don’t see a property that allows you to center align the dataPoints labels along the X axis. Is this possible?

Sorry, this feature is not available as of now.
