Wrong Calculation in the Box Plot

[dewaputrabs]

Hi Chris,

I use your boxplot graph to create a report view and the things i want to analyse is the download speed per region.

i show all region in pie chart and give the download data in boxplot chart.

but some how the view is getting wrong. when i show all the region the result will not the same with when i filter only one region.

please find the attach for the sample, i hope you got what i mean.

thanks any way :)

Hi, You can see that it does change but the number of cities on the x axis it too much for the space designated and there is too much to do layoutwise to accommodate it using d3. Instead I will be switching to High Charts for the box plot. I will respond back here. Until then, please limit the number of dim values to be just the top 10 or something that works with your layout.

Hi Chris, i know its change, but what i mean is not city boxplot, my point is in the region boxplot part. you see i only have 8 regions. and the information is miss match. when i show all 8 regions and only one region.

thanks.

I am confused, sorry. In the screenshot i see you made a selection on West Java and in the Region box plot displays only that region for West Java. What happens when you cancel or clear the selection(s)?

Hi Chris,

you seen my first screenshot ?

its show all regions ( 8 regions there and west java is one of them with 4th graph ) with value Q1= 92; Median = 151 ; Q3= 221

but in my second screenshot. i chose only one region ( west java region ) and the value is change.
as you can see when i choose only west java region Q1=269 ; Median = 586 ; Q3 = 1084.

and recently i found every time i load the dashboard the data view is some how keep changing :(

may be you should look again for the Quartal calculation.

I found the same problem. I believe the package takes only the unique values for the second dimension. I uploaded a dataset that makes it clear the boxplot is not working properly (the median should be 1 for variable y).

Hi Chris! First of all thank you for this extension. As mentioned in the previous posts. The Boxplot seems to have a Problem if there are entries with the same value in a table. I attached a screen showing my basetable, a table with the calculations (Fractile, Median) and your Boxplot. The Boxplots for A and C are correct as there are now duplicate values. B on the other hand is wrong.

It would be great if you could check on that again! Thanks in advance!
