可以用jsxgraph制作波特图

如何解决可以用jsxgraph制作波特图

我正拼命寻找如何将图放在jsxgraph下以绘制具有x轴且以对数形式演化的图。像这样https://en.wikipedia.org/wiki/Bode_plot

感谢您的帮助，

解决方法

这里是一个如何使用对数垂直轴进行绘图的示例。它改编自Murray Bourne的示例，请参见convert_bert_original_tf_checkpoint_to_pytorch.py。代码如下：

const board = JXG.JSXGraph.initBoard('jxgbox',{ 
    boundingbox: [-5,6,5,-4],axis:false
});

// Vertical axis with logarithmic scale
var attr = JXG.Options.board.defaultAxes.x;
attr.ticks.drawZero = false;
var xAxis = board.create('axis',[[0,0],[1,0]],attr);

attr = JXG.Options.axis;
var yAxis = board.create('line',[0,1]],attr);

attr = JXG.Options.board.defaultAxes.y.ticks;
attr.drawLabels = true;
attr.drawZero = false;
attr.generateLabelText = function (tick,zero) {
    return (Math.pow(10,Math.round(tick.usrCoords[2] - zero.usrCoords[2]))).toString();
}

var ticksY = board.create('ticks',[yAxis,1],attr);   

// Plot two functions
var post = (x) => JXG.Math.log10(x); 
var f1 = (x) => x*x;
var f2 = (x) => Math.exp(x);

board.create('functiongraph',[(x) => post(f1(x))],{
  name: 'x^2',withLabel: true
});

board.create('functiongraph',[(x) => post(f2(x))],{
  name: 'e^x',withLabel: true,strokeColor: 'red'
});
