getImage for dates returns blank graph

[PinnacleBot]

var dates = ['2020-05-09T17:48:49.000+00:00', '2020-05-06T17:48:49.000+00:00']
var members = [16, 9]

var trace = {
                x: [dates],
                y: [members],
                type: "scatter"
            };
        var figure = {'data': [trace]};

        var imgOpts = {
            format: 'jpeg',
            width: 700,
            height: 500
        };
        plotly.getImage(figure, imgOpts, function (error, imageStream) {
            if (error) return console.log (error);
        
            var fileStream = fs.createWriteStream('../../Bots/Pinnacle/graphs/1.jpeg');
            imageStream.pipe(fileStream);
            fileStream.on('error', err => console.log(err))
        })

This code returns a jpeg file that is a blank graph. If any more info is needed just say so
