JSPLUMB how to fetch records from database

I need some help please how can I fetch records from database and display it in jsplumb in hierarchical chart…I am not familiar with this plugin , I tried to read the docs but it didn’t show some example on how to display records from database.

Thank you in avdance

How can I use jsplumb to create dynamic hierarchical chart ,does anyone tried this before ?

Thank you in advance.

I don’t think JSPlumb has any concept of your database.
You’ll most likely have to fetch everything you need via AJAX (or just echo it to the page on load) before initializing the plugin.

Hi @James_Hibbard,

Thank you for the quick reply…yes I know how to fetch records from database via ajax,but I am confuse about the plugin how can I put the return json in the jsplumb,…I look at in there api and docs there is no example on how to handle json object to draw hierarchical chart dynamically.

Thank you in advance.

Well JSON is just a data format.
What data is JSPlumb expecting (a simple example of a chart would be nice) and what does your JSON look like?


I want to create like this


but I am confuse how to do tha,there is no example code.

Thank you in advance.

Come on jemz, just open your sample page, inspect the source and put the pieces together from there.

Here is the source code of the page you linked to with all of the unnecessary elements removed.

As you can see, the JS for drawing the chart itself is reasonably well commented, so hopefully this should give you something to go on.
