Highcharts / Highstock stepline with integer values drawing halfsteps?

Question

How can this be possible? All the values are integers and that vertical tick is set as increments of 1.

When I zoom into such halfstep period, the halfstep is not happening.

Answer 1

In general it is not supported, only what you can do is catch setExtrems() event (zoom) and load new data with new steps.
