可以通过Emscripten对GNOUPUPT进行代码转换，以在浏览器中以Java脚本的形式运行。请参见现场演示站点gnuplot + emscripten。作为结果的javascrip变体目前不受gnplot项目的支持，但是原理证明演示令人印象深刻。

Js将允许您将数据数据适合任意函数。

<script type="module">

    var f = function(a_n, x){
        return a_n[3]*Math.pow(x, 3)+a_n[2]*Math.pow(x, 2)+a_n[1]*Math.pow(x, 1)+a_n[0];

    let data = [[-3, 8], [1,3], [5,3], [9,8], [10,16]]
    var fn1 = function(a){
        let sum = 0
        for (let i = 0; i < data.length; ++i) {
            sum = sum + Math.pow(data[i][1] - f(a, data[i][0]), 2)
        }
        let sse = Math.sqrt(sum)
        return sse
    }

    let solver = new Alglib()
    solver.add_function(fn1) //Add the first equation to the solver.

    solver.promise.then(function(result) { 
        var x_guess = [1,1,1,1] //Guess the initial values of the solution.
        var s = solver.solve("min", x_guess) //Solve the equation
        let x = solver.get_report()
        solver.remove() //required to free the memory in C++
    })
