Possible to use Highcharts Scatter Plot with categ

Question

Highcharts v3.01

I'm trying to use a scatter plot to draw points within named categories (these are actually numeric, but out of series and I don't want gaps).

Using line graph types would work, but I'd rather not as I have potentially hundreds of series and scatter points are clearer.

The closest I have come is this:

EDIT - I would post a descriptive image, but apparently I need reputation points. Sigh.

Please see here: http://i117.photobucket.com/albums/o63/Harry_Flashman/close_zpsfe6d3ea2.png

This is using points referencing an x and y,

data: [{x:108432,test:100,y:0}, {x:109802,test:100,y:51}, etc. ]

I want to do exactly as above, but without the gaps.

The only way I can see to have a non-linear gap-free axis is with categories, which I've used before on other line-type graphs, but never with a Scatter Plot.

If I use the x-axis type "category" with a category array instead, it only assigns one scatter value to each and the remainder to ascending numeric categories (i.e. it doesn't group them if I use the point "name" option).

xAxis: {
  type: category,
  categories: ['108432','109802','110240', etc. ]
}

with datapoints that look like this:

data: [{name:'108432',test:100,y:0}, {name:'109802',test:100,y:51}, etc. ]

Ends up like this. Each scatter point gets its own category.

Any help appreciated, this would be great if I could get it to work.

Thanks!

PS. Added entire chart script (minus large amounts of data) below. This is the "almost works" version.

Ok, fixed it via a workaround,

Essentially in Javascript I've added a position to the point arrays relating to which of the categories the point belongs to (generated via PHP, the categories are sorted ascending). Relevant bits are as follows:

xAxis:    {
  categories: ['r101831', 'r101849', 'r101850']
}   

plotOptions: {
  tooltip: {
    headerFormat: '<b></b>',
    pointFormat: '
      <b>Test {point.test}</b><br/>
      r{point.revision}<br/>
      {point.y}% change<br/>
      {series.name}'
  }
}

series: [{
  name: 'PRd',
  data: [
  {x:3,revision:101831,test:267,y:0},
  {x:4,revision:101849,test:267,y:-1},
  {x:5,revision:101850,test:267,y:-0}
  ]}
]

End result looks gorgeous, I love HighCharts.
