An error occurred while saving the comment This is what happens if I just simply add your data to a line chart today: http://jsfiddle.net/highcharts/etda3g4t/
Can you elaborate on what you expected? Maybe with a sketch to make it clearer.

Thanks for your suggestion! You can wrap the showNoData and hideNoData functions to add your custom code: http://jsfiddle.net/highcharts/3u2crb53/
An error occurred while saving the comment It's not currently documented. What we're doing is to override the internal functions, so that we can run our own code before or after the default functionality. The principle is explained at http://www.highcharts.com/docs/extending-highcharts/extending-highcharts.

Could a polygon series work for you? http://jsfiddle.net/highcharts/n43L0a2x/
An error occurred while saving the comment Yes, that's right. Just loop over your data points.
An error occurred while saving the comment One way or another you need to feed those Y values to Highcharts. So if you don't know them, you need to compute them. For example, you could loop over the data set programmatically and find the minimum and maximum values within the given time stamp, then use those values for the polygon.

An error occurred while saving the comment Would the itemWidth option work for you? It will align the items nicely, especially when combined with the same styles.width.

For the records, it would not be seconds specifically, but X values in general.
Here’s a snippet that makes the gapSize apply to absolute X values (meaning milliseconds in our case): http://jsfiddle.net/highcharts/wado3rku/
If we implement this in the core, it should probably be called gapValues or gapSizeAbsolute, but we need to check how it works with an ordinal axis.
An error occurred while saving the comment Okay, maybe you should use axis breaks instead? http://api.highcharts.com/highstock#xAxis.breaks.
Since you'r analyzing and preprocessing your data anyway, you can look for full-hour gaps in the data and add breaks there.

Making backends for data bases is complex, as it covers a wide range of different databases and languages. A project like this would have to start with only a few of the most popular backends. We are currently considering a “connectivity” project that will do some of this.
An error occurred while saving the comment Yes, I agree with all of this, but it all comes down to Pawel's question in the beginning of this thread. Which database, and which language. There's a huge diversity out there.
We have just released a beta for a Highcharts .NET wrapper, see http://www.highcharts.com/component/content/article/2-news/197-highcharts-net-wrapper.
Our plan is to continue building on this idea. Java and PHP would be obvious next steps, but again there are diversities.
You seem to have gathered a team to upvote this feature. What particular database/serverside integration are you looking for?

An error occurred while saving the comment Nice work Grzegorz!
For better separation from the configuration, and to make it more pluggable, you could wrap the ColumnSeries.translate method and set the new x attributes on the point.shapeArgs object. Then you'll get animation for free, and you can get rid of the event handlers inside the config.

An error occurred while saving the comment Do you mean you are missing separate maps for each region of South Africa? Currently we only have the country-level map: http://www.highcharts.com/maps/demo/all-maps#countries/za/za-all
An error occurred while saving the comment Do you mean like clicks in one chart will result in changing data in another? Though we don't have a declarative API for it, it is still easy to set up using click handlers and methods like Series.update, Chart.addSeries etc.

An error occurred while saving the comment Thanks for your feedback.
1. Does your comments apply to both approaches? (table => chart and chart => table)?
2. By structuring the data differently, do you mean simply swapping rows and columns? In that case the reader would read the table row by row, and each row will hold the data for one series.
An error occurred while saving the comment Hi Ted, have you seen http://www.highcharts.com/docs/chart-concepts/accessibility? How do these different options work with your screen reader?
I'm not sure how such a scale should be implemented in practice. What tick would be next to 0?
For example, we could have ticks for -100, -10, -1, 0, 1, 10, 100. But this means two discontinuous scales, because the true logarithmic scale doesn't reach 0 at all. It could just as well be -100, -1, -0.01, 0, 0.01, 1, 100. So should we add options for where to cut off close to 0?
