I have a time-series (x-axis is Date format) which has consistent periods regularly empty, such as evenings and weekends. I am wondering whether it is possible to automatically collapse/hide a period of time on the x-axis in Dygraphs so that gaps do not appear in my plotted data? (e.g. the x-axis doesn't plot Saturday and Sundays, thus allowing Friday to run directly onto Monday).
Given that I doubt this functionality is available natively, does anyone have any suggestions on how to achieve this more manually?
As you surmised, there's no support direct for this sort of thing in dygraphs. This has been discussed on the mailing in the past.
The gist is that the dygraphs x-axis is always continuous. You'll need to map your time dimension onto something that is continuous, e.g. "market open minutes". Then you'll have to update the tickers and axis/value formatters to reflect this.
It's a fair bit of work but the necessary hooks do all exist. Please do share your solution if you go down this path!
