  1. Basically to capture the inbound and outbound bandwidth values not by overwriting on each like the ones which we already have... but to have a graph which is just one below the other

  4. For example, we currently have a plot that has three layers of groupings
    eg. We have a series of data that each point has a sample type, disease state, probe and gene associated with it. We want to move onto highcharts but would need to be able to show the sample type in the label/colour but show the breakdown for the disease state, probe and gene. See below for our current implementation in flot.

    https://docs.google.com/open?id=0B0Nu-R_YNfgIb0Fidmt1TFd1TU0

    I apologise if I can actually already do this - I thought I would ask first before I tried implementing it - I didn't see…

  5. Export should include all visible elements of the current chart, this should include all post-added elements, like plot lines and bands. Series do appear to be included if added after-the-fact, but plot lines and bands are not.

  6. You added the new feature 'between' for pointPlacement for column charts. This is exactly what I missed before, except that I need the placement of the columns between the ticks to the left, and not to the right. Could you add an option like e.g. 'between-left'?

    We plot a temperature value and a precipitation sum together in a chart. If the temperature value is measured at the beginning of the time period, the actual behavior of 'between' would be ok. But in our case, the temperature value is measured at the end of the time period...

    E.g. http://meteonews.ch/en/Weather/G2657896/Zurich

  7. If we have a series that over time is always increasing like this one: http://plus.tehk.org it would be nice to be able to ask highstock to plot a dotted line of future growth based on the average of all data for the period of data displayed. For instance, I would like to know when my count of G+ users will hit 1 billion. I could add this projected point to HighStock js and it would plot out the estimated growth out to this date.

  10. I have a need to display an area above (or below for reversed y-axis) a line. I can certainly specify a threshold above the highest value in the series, however this breaks the yAxis ability to dynamically pick the maximum end of the range based on the data. So I suggest either (a) have an option for the yAxis to ignore the threshold when dynamically choosing the min/max of the range, or (b) having special "positive infinity" and "negative infinity" values for the threshold that would of course be ignored by the yAxis ranging.

    Thanks!

  11. Reading a pie chart is like reading a clock. It's most effective to place the largest segment at 12 o'clock (as it does now). The best way to order the rest of the segments is to place the second biggest slice at 12 o'clock on the left; the rest would follow counterclockwise.

  13. when the %a is used for a dateFormat, the first three letters of the corresponding weekday defined in lang is used.
    This is a reasonable default.

    However there are languages, as German, where the usage is to shorten weekdays with 2 letters only

    Could the entries for short days be added to lang

    Of course directly using shortened day names works as well

  15. 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…

  16. Is possible to display a chart in the tooltips ?

    Like a drilldown chart which is shown at tooltips.

    I have try a few simple solution with it :
    1. I'm set useHTML option to TRUE, and applying <iframe> syntax. So basically, i make 2 chart.
    2. I'm set useHTML option to TRUE, and applying <img> syntax. So i have 1 Chart & 1 Image.

    What I dislike from my method :

    Method 1. I cannot customize tooltips size.
    Method 2. I will have a chart image, not an interactive chart

  18. I suggest you a new feature for "donut charts" (with 2 or more circles, like "browser" and "version" in your example).
    I have a real need in this feature. What is it?
    When user click on one label at the legend (which has 2 labels: "browser" and "version") this label and circle at the chart display none.
    The other data at the chart (i mean the next circles, more outlying) must regroup.
    So, if there are 2 same "1.1" version, with "5%" and "7%" at the second circle, after the regroup it must display "12%" in one sector.
    I realy…
