  3. Hi
    New pattern need to be created from the parent circle patterns for intersected data .
    Example: If one of the parent circle has vertical line pattern and other parent circle has horizontal line pattern, the intersected part should have pattern that must be the result of both parent circle. In this case it should look like square box (combination of vertical and horizontal circles).

  5. This would allow SVG paths to be shorter in many cases, which would reduce data size, and make the page load faster.

    For example, SVG path for a rectangle could be
    "M400 400h32v28h-32Z"
    instead of
    "M400 400L432 400 432 428 400 428Z"
    See http://forum.highcharts.com/highmaps-usage-f14/use-of-relative-commands-in-svg-paths-for-map-t31720/

  7. I am using solid gauge, shape 'arc'. I am trying to show round edges, on both sides. Seems like it only rounded the edge on the left, but not right.

    Basically, also round the gray edge, too

  9. It would be great if we can add an extra UI (any UI shape , triangle or arrow shape) on Angular or Solid gauge chart to indicate extra value(probably a target value or goal value) other than the current value.

    I know I can put a label anywhere (with x,y pixel values) but this is not dependant on the location of the value on graph. It would be awesome if I can put "marker" (one or more?) with a series data value to insert a shape or something similar.

  11. I have a requirement for heatmaps which involves applying a patternObject as a color for zones applied to the x-axis, but I also need the pattern fill to respect the color applied by the colorAxis.dataClasses. Is there currently a way to do this that doesn't involve applying classNames in styled mode?

  13. Most things in HighCharts have smart defaults, so unset options will do something reasonable. But plotLines is not this way: if the user does not explicitly specify a width and color, no line will be drawn (and sometimes a JS error will happen).

    Example which works but includes comments on how to easily break it: http://jsfiddle.net/LKayp/

    I think plotLines (and addPlotLines) should default to a reasonable width and color, just as regular series lines do.

  15. For a StockChart every time the user adds, removes or modifies an annotation or an indicator, either over the annotation-/indicator-popup or by dragging an annotation-control-point directly, an event on the chart instance should be fired, so that you can e.g. automatically save the chart-state every time something has changed.

    Maybe something like:
    Highcharts.Chart#events:annotationChanged
    Highcharts.Chart#events:indicatorChanged

    Hi,

    Thank you for submitting the idea.

    Basic events are already here: on chart level we have addSeries (https://api.highcharts.com/highcharts/chart.events.addSeries) and series remove – implemented, but not a part of documented API (demo: http://jsfiddle.net/BlackLabel/0cosmk2g/) or similar series destroy (the same situation).

    For series update you could use series render event (not a part of documented API).

    Events for annotation update are not yet implemented.

    How to resolve:
    Generally, this could be implemented through extending Highcharts. Related functions that create, update and destroy annotations could be wrapped to fire additional events. I’ll try to provide a POC later this week.

  16. many people don't have the idea to move the mouse over the apple watch solid gauge at the first impression, is there anyway to show one tooltip to pretend it's selected by default? or show series around the circle ?

  19. A marker like a tooltip but which will stay all the time and can be moved around on a line series chart. This marker should not disappear even if the line series data is updated.

  20. It would be very useful to calculate the speed of change in the y axis at every point in the time series. Something like this:
    chart.series[0].points[0].y.speed(year)

    speed(Year) would calculate the rate of change per year, or month or day of the Yaxis variable,

    you could also implement acceleration
    chart.series[0].points[0].y.acceleration(year)
