Hello,
Can any one provide a snipped to develop charts component with scout framework.
It will be interesting to get an example of a working charting project.
In future release will those component be introduced by default in the framework ?
Kind Regards

Hi there,

that's a question I also have for a very long time now.

The only solution I stumbled across so far, was using JFreeChart or something similar and display the output within a SVG control.

Are there any better solutions?

Peter

Hi,

there is no official chart widget provided by Scout, but it shouldn't be a big deal to use one of the many charting libraries in the internet. You basically have to create a custom field which acts as wrapper for the library. An example can be found here: https://scout.bsi-software.com/widgets/?dl=widget-heatmapfield. This field uses a library called leafletjs to visualize maps (https://leafletjs.com/). Maybe you want to start a GitHub project to share your results? ;-)

Using a server side library and creating an SVG is definitely an option as well, but the result is rather static. JavaScript based charts are probably more interactive and visually appealing (animations etc.).

Good luck
Claudio

It's hard to tell from just this error message. Somewhere, you are calling the method appendDiv() on an object that is undefined. Here is an example of a call that would cause this error:

this.$doesNotExist.appendDiv('myclass');


I suggest you add a break point in the F12 developer tools at the error location and inspect the stack trace and the object properties. Can you post the code of your widget or at least a strack trace?

Regards,
Beat
