  1. I would like to be able to configure a non-shared tooltip so that the tooltip only appears to the left or right of the point. I was able to modify the highcharts code for a custom positioner, by forcing it to swap() at the end of the routine.

    [code]
    tooltipPositioner = function (labelWidth, labelHeight, point) {
    var chart = this.chart,
    distance = this.distance,
    ret = {},
    swapped,
    first = ['y', chart.chartHeight, labelHeight, point.plotY + chart.plotTop],
    second = ['x', chart.chartWidth, labelWidth, point.plotX + chart.plotLeft],
    // The far side is right or bottom
    preferFarSide = point.ttBelow || (chart.inverted && !point.negative) || (!chart.inverted…

  2. I think the current zoom-in by mousewheel is way too fast and should be slower or controllable by the creator of the chart.

  3. Hi, I've used Highcharts in the past and love it! But right now I am looking for a charting framework that can let users explore the data by filtering it across the entire page.

    An example of what I am looking for can be found on the dc.js main page, under the Examples section:
    http://dc-js.github.io/dc.js/

    When you click on a year's bubble, the rest of the charts on the page show only that year's data.

    I would love to have this capability in Highcharts, is there any way to make this happen?

  5. Can you please add fireEvent to the list of global variables that you currently expose? This would be helpful for firing events within functions that I need to wrap such as Point.drop which uses fireEvent

    Below is from highcharts.src.js at around line 17648, see my comment below:

    [code]
    // global variables
    extend(Highcharts, {

  6. I'm trying to get the callout portion of a tooltip for a bubble chart to touch the outside perimeter of the bubble (needed because of overlapping bubbles and how the tooltips behave). I tried using the tooltip positioner but there is no information about the point (bubble) radius, so I have no idea how far to position the tooltip.

  8. I would like change the min and the max, ie for a category A I have values ​​from 0 to 200 and for another category B from 0 to 1. Currently, category B, I do not see very well because the scale is 0 to 200.

  9. We can place html formatted on the chart. But on export the ability is lost. In this example I have tried to use the subtitle for export, but HTML is lost there to and so it goes from a nice formatted paragraph with list items to a one line text on export.

  12. This is a fallout of the other request "Set timezone", which has been completed in Apr 2014.

    However, in that request, timezone was supported as a fixed offset (e.g. 300 minutes), but in human society, timezone is a geographical concept (e.g. "America/New_York") and many of them have two offsets -- due to the use of Daylight-saving time.

    IANA maintains a database of timezone (TZ) that is based on a geographical ID (e.g. "America/New_York")

    c.f. http://en.wikipedia.org/wiki/Tz_database

    GWT already has some limited support of the IANA TZ databases. The data is contained in a file called TimeZoneConstants.properties.

  14. Have the ability to pan and zoom. To do this, I suggest panning works by holding down the shift key while you drag the mouse. This way the normal zooming method of dragging the mouse will still work.

  15. We want to adjust the Bubble-Size of the Bubble Charts manually as we have 6 different bubble charts for 6 different countries which should be comparable, but not within one chart. We want to display 6 different charts but at the moment the bubble size of the biggest values of each chart is set to a maximum size, without regards to the absolute value. So the biggest bubble from chart 1 e.g with value 20 is double the size of the biggest bubble in chart 1 with value 10 if we do not arrange the maximum size for each chart…

  16. Enable overscrolling - scrolling a fixed amount of pixels (customizable, like say 20% of chart.plotWidth) to the right, so that we show an "empty" space that is waiting for new chart data.

  17. As I learned from Sebastian, it seems the BETA version of HighMaps supports GeoJSON for rendering, but does not have a function to convert a given lat/lon point to a point on the map.
    This feature would be extremely useful for visualizations related to Maps.

  20. i have time series based on persian dates, which is behind 1970 (now, we are 1392).
    setting xAxis.type= 'datetime' collapse all data as it except datetimes > 1970. tweaking xAxis.labels.format will not help because the provided {value} is collapsed before

    what can i do?
    what is the best practice to having international (and non gregorian) dates inside highcharts?
