When using the following chart options a large "NaN" is displayed in place of the bar when the data in the series array is 0. The "NaN" disappears when the stackType option is removed so potentially a divide by 0 error.
{
height: 450,
type: 'bar',
stacked: true,
stackType: '100%'
}"
Can you please create a simple codepen demo (without Angular integration)?
Sure thing, with a bit more investigation it seems to be caused by having the dropShadow property enabled on the dataLabels.
Thanks for the codepen. Will fix soon.
