Check for NaN

[andrewgoz]

I've been working on an integration of ApexCharts (which uses this library) with TiddlyWiki and noticed some exceptions in the console. I've tracked them down to the code below that has issues where the size of the chart has been set to 0 during code that is disposing of dynamically-generated charts.

svg.resize.js/src/svg.resize.js

Line 461 in b62a7b8

var aspectRatio = this.parameters.box.width / this.parameters.box.height;

Needs the following after it:

if (Number.isNaN(aspectRatio)) {
  aspectRatio = 1;
}

and

svg.resize.js/src/svg.resize.js

Line 464 in b62a7b8

var newAspectRatio = newW / newH;

needs the following after it:

if (Number.isNaN(newAspectRatio)) {
  newAspectRatio = 1;
}

Edit: It has occurred to me that this could also be done like:

if (this.parameters.box.width == 0 || this.parameters.box.height == 0) {
  aspectRatio = 1;
}

and

if (newW == 0 || newH == 0) {
  aspectRatio = 1;
}
