    <p>I am trying to edit stacked-column chart by adding/removing data and categories from highcharts stacked/column chart. But there are inconsistencies on chart as category names/value/count.</p> <p>My add function /param:data/:</p> <pre><code> //setting category names var categories = this.obj.xAxis[0].categories; categories.push(data.name); this.obj.xAxis[0].setCategories(categories); //adding new points getting the series by name this.obj.get("a").addPoint(data); this.obj.redraw(); </code></pre> <p>My remove function/param:name/:</p> <pre><code> var self = this; var cat; var data_series = []; $.each(self.obj.series, function(sKey, sVal){ var j = sVal.data.length - 1; var isRemoved = false; var dt; while(!isRemoved &amp;&amp; j &gt;= 0) { var dVal = sVal.data[j]; if (dVal.category === name) { dVal.remove(); isRemoved = true; } j--; } }); var categories = self.obj.xAxis[0].categories; categories.splice( $.inArray(name, categories), 1 ); self.obj.xAxis[0].setCategories(categories); self.obj.redraw(); </code></pre> <p>The result is like this: I can add new categories/points, stacks and columns properly. I can remove the latest categories properly, it shifts to left and they are rendered fine. But when I remove category A from the categories [A,B,C,D] the result is rendered as [C,D,3]. However, it should be [B,C,D]. And whenever I add any new category after this it increases the last number instead of the string I give.</p> <p>I am wondering what would be wrong the code above and what the proper way to add/remove categories,points,data to/from stacked column chart is.</p> <p>Here you can try it out: <a href="http://jsfiddle.net/gencay/UP55k/" rel="nofollow">http://jsfiddle.net/gencay/UP55k/</a> </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
