[Solved]-Does HighCharts have a fundamental minimum height before it's rendering behaviour changes?-Highcharts

Here: http://jsfiddle.net/BlackLabel/e9Lp3xvu/ I have reproduced the issue without Angular.

The problem is caused by the default value of tickPixelInterval for y-axis (72). As a solution you can reduce the value.

    yAxis: {
        visible: false,
        tickPixelInterval: 1
    },
