    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?

    You can just impose a bubble series on top of the heatmap: http://jsfiddle.net/803f4txt/

    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.

    This is probably possible, but what label do you mean? Can you show us a code example or screenshot?

    So you're looking to display multiple tooltips at the same time? Or will http://api.highcharts.com/highcharts#tooltip.shared help you?

    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.

    Do you have a code example where the data labels fall outside the box?

    Yes, that's right. Just loop over your data points.

    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.

    Would the itemWidth option work for you? It will align the items nicely, especially when combined with the same styles.width.

    Check out the scaling options, for example http://api.highcharts.com/highcharts#exporting.sourceWidth.

    It that is not what you expected, please provide a live demo or a screenshot of your on-screen image and its exported version.

    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.

    AdminTorstein Hønsi (CPO, Founder, Highcharts JS) commented  · 

    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?

    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.

    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

    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.

    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.

    Hi Ted, have you seen http://www.highcharts.com/docs/chart-concepts/accessibility? How do these different options work with your screen reader?
