Timeline graph - how to handle "time gaps"?

I've been working with Google chart API and annotated timeline. Drawing graphs is fine. I have no problem.

However, I need to draw a timeline graph for share prices. And as you may know, share prices are meaningful only between certain times (e.g. from 10AM to 4PM, when the mar开发者_如何学Cket opens and closes).

How do I change the Google timeline graph so that on X-Axis, the range is from 10AM-4PM? Right now, it just draws a long constant line between 4PM till 10AM next day before prices start to move again.

Man, I hope that makes sens. (Google finance chart seems to do it).

Thank you SO much for whoever can answer. You are a CHAMPION!

It is apparently now possible if you use the new AnnotationChart API: https://code.google.com/p/google-visualization-api-issues/issues/detail?id=25#c43

You could also use other, similar solutions, like dygraphs for example.

I had the same problem. After giving it a little though I found workaround. Just fill the missing values with 0 (or null) values. It will do the job
