使用chart-js lib绘制折线图时遇到问题。
这是codepen:https://codepen.io/bhupendra1011/pen/gObEpJQ,在这里我将min Y值设置如下:
Python 3.8.1 (tags/v3.8.1:1b293b6,Dec 18 2019,22:39:24) [MSC v.1916 32 bit (Intel)] on win32

Function i/p (in numpy notation): (667.38/x)*(1-np.exp((-0.146843)*x))-40
Function is: (667.38/x)*(1-np.exp((-0.146843)*x))-40
Precision: 5
Refer to the graph of the function for the start value

但是,如果小于minY的值是不可能的,则绘制的值是不可能的,如果我删除minY option,则所有折线图都是可见的,但是在我的情况下,我希望图形具有一些初始值。
我还尝试使用以下代码代替设置minY:
yAxes: [{
ticks: {
min: minY,maxTicksLimit:5
},gridLines: {
display:false
}
}]
虽然所有绘制的线都是可见的,但是图形的初始位置在选择不同的系列选项时会发生变化。以下是相同的代码笔:https://codepen.io/bhupendra1011/pen/bGNJNBw
我希望图表从某个初始值开始,还应绘制小于初始值的值,并且在更新图表时,图表的初始位置不应更改。
谢谢
