Add minPointLength for CLOSE to zero values but not for value exactly 0
We have bar and column charts with data of very distant values. Like 0.5 next to 8000000. So highcharts scales itself in the way that this small values are invisible without zooming.
There is an attribute minPointLength (http://api.highcharts.com/highcharts#plotOptions.column.minPointLength) that makes such samll values visible. But the problem is that value 0 is also rendered then. So we would like to have. minPointLenght behavior for close to zero values but NOT for value 0.
For us distinction between null and zero is important (null - lack of measurement; zero - measurement of 0 value)
If you don't want to render 0 values, perhaps you should add null values instead?
