How to pass data from PHP to JS charting?

Hello, my question is, how EASY it is to construct graphs from given values that are in the database. Data then I can easily from the database to pull out, but in the JS file with graphs to convey in any way.. there is only one method via window['var1'] = '<?php echo $var1?>';
but each variable to throw very expensive, and in the graph data and 10-20 3-5 graphs on the page.
As you can easily pass values from PHP to JS charting?

data: [18, 16, 19, 19, 18, 14, 14, 20, 15, 16, 18, 19, 14, 20, 19, 15, 16, 18, 12, 14, 20, 19, 15, 16, 18 ]


P. S JS file with the charts is in a separate file.

Knock via JS to the server, get your data and then render graphics.

Search in Google (with quotes): "REX Tiny templater"
Then, you need to create a json object and pass it to PHP and use.
Example:
str = "When <?=$var['m1']?> came from <?=$var['m2']?>, weather <?=$var['m3']?>.";
vars={'m1':'we','m2':'Park','m3':'began to deteriorate'};

console.log(getvars(rex,str)); //Array[3] => ["m1", "m2", "m3"]
console.log(setvars(rex,str,vars)); //When we emerged from the Park, the weather began to deteriorate.

Read about AJAX.
The point is that JS "knocking" to PHP, asking him for data.
He says, it is called rest api.
I would advise you to start with get post requests - kavon.Deckow commented on April 4th 20 at 13:12
@kavon.Deckow, get and post requests and there is a REST API. - Destany_Bradt commented on April 4th 20 at 13:15
@Destany_Bradt, you know, I mean that the author should study first what is get/post and then to the rest API. And then Google for the rest API gives immediately about how to build rest about the missing database queries - kavon.Deckow commented on April 4th 20 at 13:18
