  1. 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.

  2. 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

  5. I have the following in a legend:

    labelFormatter: function () { return this.name + " - " + this.value; }

    That looks fine, except, I want to remove the " - " and have all the values aligned to the right in their line.

  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. Sometimes we want to see more information in one data series, so a single Y value isn't enough. For example, I want plot a stock series where Y represents price and color/brightness represents the volume.

    I started a discussion on this topic in the support forum:
    http://highslide.com/forum/viewtopic.php?f=12&t=22326&p=87651#p87651
    and people suggested I post here.

  9. Have a simple 3 bar graph. The containing DIV has no height defined Graph ends up rather tall with THICK bars. Ugly. If I try to control the bars by setting the plotOptions.groupPadding to .1 and pointPadding to 0 and the series I set pointWidth to 20, end up with lots of white space but graph is STILL taller than it needs to be.

  12. Most things in HighCharts have smart defaults, so unset options will do something reasonable. But plotLines is not this way: if the user does not explicitly specify a width and color, no line will be drawn (and sometimes a JS error will happen).

    Example which works but includes comments on how to easily break it: http://jsfiddle.net/LKayp/

    I think plotLines (and addPlotLines) should default to a reasonable width and color, just as regular series lines do.

  16. add margin setting between top of chart area and zoom / data range row. currently one has to set top variable for all axis to move them all uniformly, also offset for axis labels and axis title not uniform, they should all take into account the opposite value of axis and move as group, also spacing between labels and axis title not dynamic, the width of the labels can leave to much space or to little, even overlap. comments specific to highstock, not sure if highcharts works same way

  19. Currently, when clicking < or > of scrollbar, the time line moves.
    But when pressing < or > of scrollbar, the time line doesn't move.

    Our users want to be able to move the time line continuously by pressing the button of scrollbar. Can you enhance it?

  20. We are using a touchscreen.
    At highchart there are two small buttons over the scrollbarbutton.

    http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/stock/scrollbar/height/

    I am not able to change the dimensions of this small buttons which are used to change the timeselection.
    This property can also be combined with the dimension of the scrollbar { height: XX, width: XX}
