How can i write javascript functions inside configurations using python

1

Hi, @Team quick chart below is my code, I want to convert my point’s background color according to the y-axis scale.
Please help me with this

js_point_color_formatter = """
    function(context) {
        var yValue = context.dataset.data[context.dataIndex];
        if (yValue <= 10) {
            return 'green';
        } else if (yValue > 10 && yValue <= 20) {
            return 'red';
        } else {
            return 'blue';
        }
    }
"""
options = {
    "devicePixelRatio": 2,
    "format": "png",
    "backgroundColor": "#ffffff",
    'chart':{
    'type': 'line',
    'data': {
        'labels': ['January', 'February', 'March', 'April', 'May'],
        'datasets': [{

            'borderColor': 'rgba(255, 99, 132, 1)',
            'borderWidth': 1
        }]
    },

Hi @pranuu91,

The easiest way is to use the quickchart-io python package.

One option is to define the configuration as a string, and substitute your function: code example

Another option is to use QuickChartFunction to define your function: code example

Hope this helps!
