chartjs-plugin-colorschemes not working.

[shashwat4348]

Hi, I am new at programming and I just started a Flask project related to Stock Market. In the chart under "function Stock_Performance_Chart2()" I am using the plugin but it doesn't seem to work (All the different lines of the chart posses the same color i.e. Grey). Can you please help me regarding this. I will be very thankful if you do so.

`function initialize(){
var active = "Active";
$.ajax({ url : '/api/initialize/user_check?JsStatus=' + active,
success: function (data) {
var user = data['user'];
var firsttime = "yes";
var olduser = "no";
var modified = "error";
if (user == firsttime){
window.location.replace("http://127.0.0.1:5000/First_Login");
}else if (user == olduser){
window.location.replace("http://127.0.0.1:5000/Scratch_start_1");
}
}

});

}

$('#quickstart').click(function() {
