  1. Currently, I can use a step line to draw non-continuous data. However, the rendering of the first or last data points in a series does not show the leading or following horizontal data line.

    For example, the last data point in the first series represents the data from Apr to May. However, the rendering makes it seem like it's only data for Apr and that there's a gap in data between Apr and May.

  4. Support background textures on solid color UI elements like Pie and Bar charts.

    Ideal solution would be angled lines in the charts for example http://www.inetsoft.com/images/screenshots/controllingtextureinabar_chart.gif

  5. Allow percentage value for option dataLabels.distance (percentage of the pie radius). That way I can make sure that the labels fit inside their slice for every label length and pie size.
    http://jsfiddle.net/kzoon/ntDX9/ shows what I mean. If you use distance -30 longer datalabels go outside their slide. If you use -50 they fit, but that will mess up small pies (100px).

  6. Hi All,

    I'm making a dashboard using Activity Gauge (http://www.highcharts.com/demo/gauge-activity) to show data.
    I need to make it with gradient effect like darker to lighter which seems not possible with linear or radial gradient logically it seems not possible.
    some how I have written an script with the help of support guy but seems not perfect solution as it do not have good visualisation and performance on browsers (very slower to load) see my samples -
    http://jsfiddle.net/td2v4u4z/47/
    http://jsfiddle.net/td2v4u4z/48/
    http://jsfiddle.net/td2v4u4z/52/

    I need charts with more sharp lines and clean curves like http://www.highcharts.com/demo/gauge-activity

    Can any one suggest me the perfect…

  7. On plotting multiple y Axis-es that are not opposite to each other.

    There would be a need to scroll down to see the common X Axis and the navigator

    This would provide a feel of floating X Axis and the navigator

    Below is the example of my JS fiddle

    https://jsfiddle.net/ynfbcxzo/

    Detailed discussion on the same could be found in the below thread:

  9. Problems:
    1. Highcharts is awesome, but consumes too much of resources on less performant systems
    2. jQMobi is fast, building Apps with jQUI a joy, but getting it to live in harmony with Highcharts + jQuery on the same page can become quite a hassle and re-introduces the (comparably slow) jQuery into your app.

    Having a jqmobi adapter would be great.

    See https://github.com/01org/appframework for jqmobi reference and code.

  10. I would love to see interactive histogram charts. Ideally I would pass a single series of data to the chart, along with a default number of bins. Then the user would be able to change the number of bins and the data would be re-binned and the chart re-drawn. Bin labels would be need to be regenerated automatically as well, either from the range of each bin, or its center-point.

    An example:

    Series: { data: [1,2,1,2,1,2,3,3,4,4,4,4,4] }
    Histogram: { defaultBins: 2}

    would become:

    xAxis: { Categories: [ "1-2", "3-4"] }
    Series: { Date: [6, 7]}

    Then if the user changed…

  14. I would like to have an approximation function in which we can access all the information from the points instead of just the y values. This allows me to not only decide how to group but also an ability to capture information from all the points into the grouped point.

  15. It would be nice if it is possible to create a bar chart with labels like the pie chart. I need to be able to create the labels outside the column and create that line to them. Just like the pie chart does here:
    http://www.highcharts.com/demo/pie-basic

    I have a Stacked Bar Chart that shows percentages and the labels wont be visible if the value is too small. or if I make them visible they will be overlapping.
    Here is an Example Fiddle to show the problem

  16. I have four series of data, and each series only has one data point. I would like to render these data with x-dimension zoom ability as good as 4 data points in one series. If this is a duplicate topic, I am really sorry, because I could not find a similar one.

    Here is the fiddle: http://jsfiddle.net/yMSCZ/8/

    I was trying to approach it by adding dummy x value to each data point from each series: http://jsfiddle.net/yMSCZ/9/ But it did not work out.

    I understand in the first fiddle, HC will treat all the four points with the same x index,…

  17. The candlestick stock chart requires data in the format of OHLC. For intraday candlesticks, it would be easier to feed the raw tick by tick data and have the chart figure out the candles based on the current data grouping.

  18. I would like to have all axis labels rendered with the same number of decimals. Currently, I can fix the number of decimals using the format string, but when zooming in, more decimals are often necessary.

    In statistics, it is a general consensus to have axis labels with the same numebr of decimal places to indicate the precision level, so I suggest Highcharts to support this, too, without reverting to custom code.

    Currently, it can apparently only be done using custom event code, see this Highcharts Forum entry:
    https://forum.highcharts.com/highcharts-usage/how-to-have-all-yaxis-labels-show-same-number-of-decimals-t40826/

    Thanks for your consideration!
    J.

  19. If I tend to display huge volume of data, chart GUI is not stretching to accomodate all contents, instead it reduces their dimensions to incorporate them within given area. This makes chart unreadable, also leads to overlapping of data during display. It will be great if chart length grows horizontally on more data and provides a scroll bar

  20. It would be most useful to restore the "target" option in the "credits" configuration so that when the user clicks on the credit text (usually in the lower right angle of the graph), the link can be opened in a new page instead of the current one.
