Highchart configure appearance when x-axis has many categories - highcharts

Question

I choose bar chart, because my graph has many categories, so I think it's a better aproach than a column chart.
I choose the following source code for making a start:
http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/bar-stacked/
However, when I put many categories, the category labels get overlapped one each other. I firstly solved it making the container higher.
However the result is not as I expect, because I got a lot of "padding" between the beginning of the graph and the first category label, also between the last label and the end of the graph:
See fiddle:
http://jsfiddle.net/Ra6Mc/20/
The code below:
$(function () {
var categories = ["ANALOGO","ANALOGO KLORNER","AÑADIR UNA PIEZA ","AÑADIR RESTO PIEZAS","ARANDELA DE ORO","ARANDELA ZOCALO","CAJITA","CALCINABLE","CALCINABLE DIAMETRO 4","CALCINABLE KLORNER","CARILLA EMPRES","COMPLETA DEFINITIVA","COMPLETA PROVISIONAL ","COMPOSTURA","COMPOSTURA PROTESIS","COMPOSTURA SIMPLE","CORONA CIRCONIO","CORONA CIRCONIO SOBRE IMPLANTE","CORONA EMPRESS SIN METAL","CORONA JACKET CERAMICA","CORONA METAL CERAMICA","CORONA PROVISIONAL CEMENTADA","CORONA SOBRE IMPLANTE","CUBETA DE RESINA","ESQUELETICO BILATERAL 1-3 PZAS","ESQUELETICO BILATERAL 3-5 PZAS","ESQUELETICO BILATERAL 5-8 PZAS","ESQUELETICO BILATERAL 8-14 PZAS","ESQUELETICO UNILATERAL 1-3 PZAS","FERULA DE BLANQUEAMIENTO","FERULA DESCARGA","GANCHO UNIDAD","IMPLANTE PROVISIONAL ATORNILLADO","MERYLAND PIEZA","PARCIAL ACRILICO 10 PZAS O MUÑON","PARCIAL ACRILICO DE 1-3 PZAS","PARCIAL ACRILICO DE 4 PZAS","PARCIAL ACRILICO DE 5 PZAS","PARCIAL ACRILICO DE 6 PZAS","PARCIAL ACRILICO DE 7 PZAS","PARCIAL ACRILICO DE 8 PZAS","PARCIAL ACRILICO DE 9 PZAS","PARCIAL ACRILICO PROV. 10 PZAS O MUÑÓN","PARCIAL ACRILICO PROV.

});
});
Just to know:
- On my navigator I can see all the category labels, however with jsfiddle I only get some of them.
- Not all my series have all the data, thats why I put the data in the series with the expression categories.indexOf().
