  1. The chart calculates the tick intervals for yAxis.
    It is possible to set tickPositioner function or add custom tick positions, but what if I only want to add a single tick? Is it ok to override the entire native tick calculation function?

  2. Hi,

    We want to add stacks in reverse order without touching legends order. I tried to dig into code and found that while (i--) unconditional
    you can add new property so that generic solution can be applied


    Code as in 3.0.7

       /**
       * Build the stacks from top down
       */
       buildStacks: function () {
              var series = this.series,
                     i = series.length;
              if (!this.isXAxis) {
                     while (i--) {
                           series[i].setStackedPoints();
                     }
                     // Loop up again to compute percent stack
                     if (this.usePercentage) {
                           for (i = 0; i < series.length; i++) {
                                  series[i].setPercentStacks();
                           }
                     }
              }
       },
    

    Proposed code with new property

    buildStacks:…

  3. I was able to draw only technical indicators like Linear,SMA,EMA,MACD in highcharts. But is there any js like technical-indicators.src.js is avilable in highcharts to draw fibonacci retracement in highcharts?

  4. Please provide some configuration function to specify space after the last data point. In real time charts, last point updates at edges of the chart, which is inconvenient for the viewers to continuous watching. Particularly for stock market real time chart.

    My Idea is not new it is followed in all the standard Charting programs in the market. It will have some space between the last point and edges of the chart. it makes viewing comfortable.

  5. When clicking on a legend item, the behavior is to hide/unhide the selected point or series. I'd like to be able to change this behavior to generate a click event on the corresponding point or series. For instance, I had to write a custom click handler to drill down when clicking on the legend item.

  7. Would it be possible to add a performance 'bar' for charts like bar and column charts. This 'bar' is really just a line, with arrows on the top and bottom, that indicates the higher and lower performers (assuming you passed in a sorted list of data). This 'bar' would sit beside the chart (for bar charts) or underneath the chart (for column charts).

    You can see an image of this enhancement request next to the bar chart in this link https://github.com/highslide-software/highcharts.com/issues/2539 (sorry for posting an enhancement request on GitHub)

  9. I'm aware that a similar idea has been completed (http://highcharts.uservoice.com/forums/55896-general/suggestions/1813731-hiding-of-y-axis), but what I'm asking for is different:

    There are a LOT of users asking for how to hide an axis completely:
    http://stackoverflow.com/questions/10877927/hide-axis-and-gridlines-highcharts
    http://stackoverflow.com/questions/15277405/highchart-show-hide-an-y-axis-without-hiding-the-series
    http://stackoverflow.com/questions/17409041/highcharts-hide-xaxis
    etc.

    Can we just have a property called "visible" on the Axis object that would show/hide the axis?

  10. When you have a lot of charts running and calling web services if you export one it will kill those web service calls. If you allow the user to set a target on the form then the export can post for example to a hidden iframe.

  11. It would be a nice feature (especially for highstock) if we could change the height of a pane (yAxis) by clicking on its horizontal boundary and dragging it (simultaneously changing the height of the adjoining pane)

  13. Default highstock tooltip formatter use color of chart in series name. But OHLC/candlestick has two kind of point colors - color & upColor and tooltip can show one of them for differnet points.

  14. When the gauge y-axis range is set from -50 to 50 and the actual value is 60, then the needle stops at 50.

    However, it would be preferred that the needle is put slightly BEYOND the 50 to indicate that the value is actually outside the y-axis range.

    this will prevent the user from accidentally thinking the value is 50.

  15. When I create a stacked bar or column chart with the stacking set to "Percent", the negative percentages should be shown in a negative axis.

    As shown here in Excel: http://i.imgur.com/R3RboAe.png

  16. I will even provide sample code. If I have a chart with automatic y-axis labels: 3 minutes 8 minutes, 14 minutes, it looks stupid. It should be 5, 10, 15 minutes and similar adjustments should be made for other increments as well. Adjust for irregular points by raising the max slightly and / or dropping a label.

    Sample Code (works well enough):

    var FitTimeAxis =
    {
    getAxisData: function (max,intervals)
    {
    var data = {};
    data.max = this.getMaxValue(max,true);
    data.interval = this.getMaxValue(data.max/intervals, true);
    return data;
    },
    getIncrementsArray: function(levels)
    {
    levels = isTrue(levels);
    var arr = [];
    arr.push(15);
    arr.push(30);
    for (var i=1;i<=15;i++)
    arr.push(60…

  17. I would like to add vertical line markers to mark for events which happened during the time-series data (like device reboot). Like flags from Highstock, just without any label associated and line going from top to bottom. With axis flags it is hard to precisely see when the event occurred when having multiple series plotted. And because the event is for multiple series all together, it is not reasonable to put them onto a particular series.

  18. Take the editor interface from the cloud product and provide it as an optional library for privately hosted charts. Therefore, we can allow our users to dynamically format a chart (according to what we want to allow) with hooks so that we can privately save their changes.

    For example, I want to allow users to customize the series color, marker size, style, etc. I can build my own web interface to collect/store these settings, but it would be great if there was a canned one that I can just plug in and capture the changes.

  20. Currently the error bar does not show up in legend. Error bars can be used to show various data (e.g. blood pressures) and we need a way to show it in the legend.
