Alternative to Box Plots for large datasets?

[dwqlik82]

Hi,

Was just wondering if people had a good alternative that would generate something similar to a box plot but would work for large-ish data sets (from my testing the dreaded *showing a limited dataset appears about 31000 rows ish depending).

I've built a stacked bar combo chart using something like the default Tukey rules (used combo so i could create a transparent offset) but it seems a bit clunky (and hides outliers):

currently have both within a container with conditional hide/show depending on the rows in the current selection, was just wondering if other people had hit similar issues and other ways people had handled it (also if anyone has a decent idea on the actual row limits for the limited data set appearing that would be great)

thanks

Dale

Alternatives may be not to use a single object else several ones which are placed side by side and/or overlapping each other. Adjusting all needed layout-features and trying to synchronize multiple objects to each other is not always easy and some disadvantages may remain - in regard to show/hide, exports/prints and/or using any popup-features and/or direct selecting within the objects ... Also thinkable is to use a straight-table with mini-charts and/or colored numbers of ascii chars ... or maybe using line-charts ...

More helpful may be to re-consider the entire approach regarding to the most important information which should be provided with the chart and if there may other and more suitable views.

Cheers, i'd guessed as much but hoped I'd missed something,  I found the box and whisker chart good for comparing median and spread of across multiple dimensions and presenting it in a relatively easy to understand view (in my case looking at the time between occurrences of X then splitting it either by Department, Date, Weekday etc to try and let people investigate if wider variability is focused in certain areas). I may see if just expanding out my pseudo box plot based on a combo chart and making it a bit more readable may work.  Nuclear option is building an extension to do it but that is usually far more effort than its worth 🙂

Thanks again
