Highcharts Javascript API

  1. make a demo which puts multiple lat/lon based Pie-charts on map

    Basically it's like the demo maps "Highmaps lat/lon" or "Map-Bubble", but then, instead of single data bubble puts multiple data pie-charts in an area.

  2. highstock

    HighStock chart is not reflects the data related to type column. Like it is reflecting for highcharts for type column, by doing addseries() method.

  3. Positive color

    Since the release of Highcharts 3.0 we have the threshold option and negativecolor. It would be nice to be able to have a positivecolor also and color anything above the threshold instead of only values below the threshold.

    For example right now i have a different color for each serie. And i want to use the threshold to change the color if above a certain threshold. Right now this means the color for each serie becomes the same for anything below the threshold.

  4. Time axis in common increments

    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*i); …

  5. Can you provide a 3-D pie chart

    Can you provide a 3-D chart option such that
    1) The size of each slice (angular radians) is determined by numerical data in one column
    2) The height of each slice is determined by numerical data in a 2nd column
    3) The color of each slice is determined by numerical or categorical data in a 3rd column
    4) The radius of the slice (extension of the edge from the center) is determined by numerical data in a 4th column.

    In this way, one pie chart can show 4 sets of data with the axes being radians, height, radius and color.

  6. tooltip to support customization of value (rather than just point.y)

    If point.y is "1024000", I will like to easily customize the tooltip to show something like: 1024K, 1Mbps, 1.023e6, etc. instead of "1,024,000".

    At this moment, I can only create a whole brand new "formatter" function. It would be much better if we can have a value_formatter just to craft the format for point.y.

  7. Allow mean/average on Column Range Charts

    It would be great if you could add mean/averages or another range to each column range entry. i.e. similar to stockchart candlesticks but for categories instead of date ranges. Or is this already available?

  9. Draw an area between two line-charts...

    ... without stagging. That means showing the real datapoints of the top line.

  12. Create Guide Line Option That Follows Mouse

    It would be nice if the charts support having a guide line that follows the mouse cursor, similiar to Campaign Monitor. Also the ability to make it dashed would be great. Currently I could plot a line manually but it does not work currently with alternating row colors.

    Something like:
    HoverGuide: 1 >>> etc.

  13. non Gregorian datetime

    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?

  14. Add config setting so as to force tooltip left or right of point

    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…

  16. Add an option to disable tooltip animation

    It would be nice to have an option to disable tooltip animation. On IE8 and less (we are still required to support these browsers!), the javascript engine is so slow that the tooltips don't animation nicely anyway. Also, there are bugs that can cause IE render problems when the tooltips animate. See http://www.tehuber.com/article.php?story=20120424082911788 for more information.

  17. Allow to complete xAxis Labels values across the axis for one data point

    https://www.dropbox.com/s/tt98crsl90av8sw/2015-07-21_17-45-02.png?dl=0

    In a case of one datapoint, a single axis label is presented, and it is quite ugly.
    Please supply an indicator to complete at least two 'bogus' labels with automatic relative values (in the stated example - 750 and 2250).

  19. Add Step Property for X-Axis Grid Lines

    For example if I use the "step" attribute to only show labels for the first day of each week, the chart still draws x-axis gridlines for each datapoint instead of where the labels occur. It would be nice to have separate step property specifically for the x-axis gridlines. This is useful if you want to break up the data into weeks or months and allow the gridlines to serve as indicators of where these blocks occur (i.e. a grid line only at the start of the week or month, etc.).

    Example:
    xAxisGridLineStep = 7

  20. allow override of automatic adjustment of datetime axis

    I have a datetime x-axis. Right now, my graph is automatically turning it into a weekly view, but it only shows the dates on the x-axis every 7 days. It would be great if I could force it to 'day' instead of 'week' view so that I can see every date on the axis, or change it so that every day of the week shows up.
