1. 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(60i);
   arr.push(3060);
   arr.push(4560);
   for (var i=1;i<=48;i++)
   {
   arr.push(i3600);
   if (levels)
   arr.push(i3600 + 3060);
   }
   },
   getMaxValue: function (number,levels)
   {
   var arr = this.getIncrementsArray(levels);
   for (var i in arr)
   {
   if (arr[i] > number)
   {
   return arr[i];
   }
   }
   return number; // if too large
   }
   }

   FitTimeAxis.getXAxisLabels(29*60,3);

   Yes, no problem. You just need to remove titles, legends, axis labels et cetera that don’t fit into the small space.

4. Add a Performance indicating 'bar'

   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)

6. Add a custom tick to yAxis

   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?

   Use `tickPositioner`. In the callback, you have access to `this.tickPositions` so modify this array (e.g. by adding one tick) as you wish.

7. Absolute Size Value of Bubble Charts

   We want to adjust the Bubble-Size of the Bubble Charts manually as we have 6 different bubble charts for 6 different countries which should be comparable, but not within one chart. We want to display 6 different charts but at the moment the bubble size of the biggest values of each chart is set to a maximum size, without regards to the absolute value. So the biggest bubble from chart 1 e.g with value 20 is double the size of the biggest bubble in chart 1 with value 10 if we do not arrange the maximum size for each chart individually.

   BUT: As these options are relative and not absolut, i think there should be a necessary option, to just set the radius of e.g. 100% or 1000 units, so that the bubble size doesn't depend on the very special data.

   E.g if numbers change over time, this would mean earlier values would be different in size than new values. This doesn't make sense.

   We arranged to use an extra Javascript now, which checks the highest value in all used .csv documents and sets the radius for each chart individually, so they will be comparable… not nice, but it works and even better if it would be an option within highcharts!

   That’s a good idea, and I think a much needed feature. I implemented it now as two new options on the bubble series, zMin and zMax. See http://jsfiddle.net/highcharts/MGqEp/. Please report back if this solves the problem for your case.

9. Add ability to export charts with HTML formatted text.

   We can place html formatted on the chart. But on export the ability is lost. In this example I have tried to use the subtitle for export, but HTML is lost there to and so it goes from a nice formatted paragraph with list items to a one line text on export.

15. Float Legend and Reset Button

    add the capability for the legend and the reset button to float when you scroll vertically? That way it is always within view when scrolling. I see a ‘float’ property for the legend, but it doesn’t behave as I thought it would.

    Since Highcharts 5 there is support for scrollbars on any axis, so the legend will stay.
