As you can see bellow you use the same code with just different type of chart.
For the first group (area, bar, column, line) you can set stacking – “none”, “normal” and “percent” and charts will look differently:
none = all series have minimum together on yAxis minimum
normal = every point on xAxis shows sumary of values of all series from yAxis – values are serialized so you see how big part belongs to every series
percent = sumary of all values in given xAxis point is taken as 100% and you can see how many % was fulfilled by every series (can be little confusing – you always see 100% regardless total sum)
I would say that stacking can sometimes be confusing and can make chart interpretation harder.Therefore I recommend to use it only when you are sure that it will help to read data from the chart.
Note about chart type “line”: although you can use also stacking type “normal” and “percent” with this chart I think in this case it really does not make sense.Because probability of error judgement of results based on such chart is really big.
The same code as by “pie” chart. Only different type “pyramid” and I added marginRight to narrow picture.If you fiddle with chart.type.marginRight value pyramid will becomme narrower or wider.Also title is different.
