Infinite loop when parent offsetWidth is invalid

[gpfunk]

Expected Behaviour

The code to gracefully handle invalid parent offsetWidth

Actual Behaviour

The code ends up infinitely looping looking for a valid number

Steps to Reproduce:

• change this
  

  charts/docs/index.html

  Line 34 in 68906af

  <div id="chart-composite-1" class="border"><svg height=225></svg></div>

  
  to

<div id="chart-composite-1" class="border" style="width: 0;"><svg height=225></svg></div>

Frappé Charts version: Tested on latest, but existed prior as well

This is an extreme example (explicitly setting a width to 0), but its just an illustration for when a parent offsetWidth is invalid (<= 0). Not sure if this should be handled by the lib though, or whether the user should be required to making sure the container is setup correctly.

A fix that I'm using is switching:

charts/src/js/charts/AxisChart.js

Line 164 in 68906af

if(this.is_series) {

to:

if(this.is_series && allowed_space > 0) {
