How to make a graph using PHP from oracle

Question

I want to create a graph that the data are from oracle by using php. I did not found example that use oracle as a database. Mostly are from mysql. The data is like this

Answer 1

Since the data is this:

 [{"0":"8","QUANTITY":"8","1":"Set A","PACKAGENAME":"Set A"},{"0":"5","QUANTITY":"5","1":"Set B","PACKAGENAME":"Set B"}]

You have a case sensitivity problem, which makes the array var packagename and quantity empty/undifined.

You need to change:

    for(var i in data) {
        packagename.push("Packagename " + data[i].packagename);
        quantity.push(data[i].quantity);
    }

... to ...

    for(var i in data) {
        packagename.push("Packagename " + data[i].PACKAGENAME);
        quantity.push(data[i].QUANTITY);
    }

I am not familiar with Chart.js but fixing this so that you are not trying to graph undefined variables is a first step.
