@shibsankar-jana,

Please refer this article for executing JavaScript inside cron job (where you can render and export chart as image). In order to save chart as image on the server, you would require a headless browser like PhantomJS. Please refer this article for the same.

@jason1028,

Adding exploded property to dataPoints after reading it from the database and parsing it should work fine in this case.

If you are still facing the issue, kindly share a sample project along with sample database over Google-Drive or Onedrive so that we can run it locally at our end, understand the scenario better and help you out.

@khanhle,

Sorry, this feature is not available as of now. However, you can change the color of all the legend text using fontColor property of legend.

@akilesh1,

Sorry, range for x-values is not supported as of now. However, you can take a look at range charts like range-column, range area, range spline area that accepts range of y-values.

@dillon,

Please take a look at the following examples to create a chart from database using:

1. PHP
2. ASP.NET MVC
3. JSP
4. Spring MVC

To auto-refresh the chart every 3 seconds, you can use setInterval() method to call an AJAX request whose response can be parsed to update the chart dataPoints accordingly. Please take a look at this documentation page for updating chart dynamically using an AJAX request.

In case the above resource doesn’t help, can you kindly let us know the Server Side technology you are using so that we can help you out with an appropriate solution?

@b_juarez,

Please take a look at this Gallery Example for rendering chart with data from the database. You can also download PHP sample from our download page.

If this doesn’t help you resolve the issue you are facing, kindly share sample project along with sample database over Google Drive / One Drive so that we can run it locally at our end, understand the scenario better and help you resolve it.

@gargprateek526,

You are passing Column as chart-type in the code shared above which is not a valid chart-type. Changing chart-type from Column to column should work fine in your case. Please take a look at this updated sample.

Please refer to this documentation page for more information about chart-types available in CanvasJS.

@fluid,

Whenever you move finger/pointer on the chart, the chart has to know if you are trying to scroll the page or interact with the chart. Hence we have implemented a behavior where if you hold the finger for a while on the chart, it captures the event and doesn’t scroll the page. On the other hand, if you move pointer/finger quickly without pausing, it allows you to scroll the webpage. Kindly check the behavior and let us know if it works as briefed here!
