Can we disable the signal emitted by the triggering of the Timer?

Parvati

A sine wave was plotted using a timer with the help of values written in a text file.On every triggering(on opening the page containing the sine wave), the time period of the sine wave decreases resulting in a frequency increased sine wave.

On observation,it is understood that on each triggering ,a new signal is emitted in addition to the existing signal. Can this be avoided ? can anyone suggest a solution so that the time period doesn't decrease and remain constant.

//        Timer {
//            id:mytimer
//            interval: 100
//            repeat: true
//            running: true

//            onTriggered: {
//                timeStep++;
//                var k = classA.floatarray[0];   
//                classA.readtext(); /*function that reads sinewave values from the file*/
//                series1.append(timeStep,k);
//            }
//        }
