I have constructed a gant type chart using nan values to create the gaps. It works well but if my 'bar length' is very short and I zoom out I reach the point where my data is not drawn.

That is all behaving as it should but I am looking for a way to set perhaps a minimum line length of x pixels. I appreciate it will not be a true representation of the data but it would show me where I need to zoom in to find the interesting data.

Is there a better to way to 'show' 'hidden' data?
