Data is not distributed through out the whole x axis

[arslan437]

I am loading data from the file that contain the time stamp and temperature reading.

Difference between two data point can be same or some time it can be a month or so.

Can we update the x axis scale so it min and max value matches the data received.

call back function of the zoom plug in is

        let timer;
        function update_chart({ chart }) {
            clearTimeout(timer);
            timer = setTimeout(() => {
                var { min, max } = chart.scales.x;
                // console.log(min);
                // console.log(max);
                console.log("Min Location: ", chart.scales.x2.min);
                console.log("Max Location: ", chart.scales.x2.max);

                
                var file_min = chart.scales.x2.min;
                var file_max = chart.scales.x2.max;

                file_min = makeCorrection(file_min);
                file_max = makeCorrection(file_max);

                console.log("Zoom level", chart.getZoomLevel());

                var total_sample = (file_max - file_min) / 116;
                console.log("Totoal samples: ", total_sample);
                var offset = (total_sample / 50) * 116;
                offset = makeCorrection(offset);
                console.log("Offfset: ", offset);

                var xhttp = new XMLHttpRequest();
                xhttp.onreadystatechange = function () {

                        if (tex[0] == ">") {
                            window.alert(tex);
                        }
                        else {
                            dataray = tex.split('\n');
                            //console.log(dataray);
                            dataray.forEach(element => {
                                dat = element.split(';');
