Its a bit of a silly setting from Google Prior to version 45 there was no issue as long as you set the width correctly.
eg: 'width':$('.tab-container').width()
Now even when you manually specify the height and width of the chart Google cant calculate it correctly- but it only affects the labels, not the rest of the chart.
Drawing the chart on tab load is a bit of a pain, as another recent change made it more important to use google.charts.setOnLoadCallback() - otherwise some charts will fail to draw in some browsers due Google load timing.
Manually setting to version 45 seems the best solution for legacy charts without re-writing all the code.
