Over on Twitter, I got here across this fascinating chart, aptly titled – Joyplot. it is the type of chart that makes you all curious and awed. So I did what any Excel nerd would do. Recreated it in Excel of direction. This submit takes you via the method.
top time for activities and amusement #dataviz. About time for a joyplot; might do a write-up on them. #rstats code at https://t.co/Q2AgW068Wa pic.twitter.com/SVT6pkB2hB

First let me share the final outcomes.
Joyplot in Excel – peak time of the day for activities and leisure
right here is the final overlapped area chart with just a little of formatting thrown in. it is an attractive close imitation of Henrik’s customary chart. click on it to amplify.
creating Joyplot in Excel – Tutorial
As that you may wager, the chart is a simply an overlapped area chart (ie each and every area sits behind another, in contrast to stacked enviornment chart where they are umm, neatly, stacked!)
Let’s delivery with a glance at facts. Henrik’s original statistics has 10,656 rows, every row containing recreation identify, time and p value – how a whole lot survey respondents enjoyed [@activity] at the moment.
here's a photo of first few rows.
Scrubbing and re-arranging the records
As you can see, whereas this structure is brilliant for storing, it is very tedious if we wish to make one chart with all sequence. So let’s scrub.
We need to determine if an endeavor may still be included or now not. i am using the equal standards as Henrik’s. Exclude actions with p value less than 0.003 or endeavor title “taking part in activities n.e.c. *” (no longer in different places categorised)
To do this, we first pivot the information on pastime and max(p). Then filter this pivot two ways – max(p) >=0.003 and label no longer equal enjoying sports n.e.c. * Tip: You may wish to allow dissimilar filters per field within the box settings of row labels.
we will emerge as with 28 actions.
Then add a helper column to common desk that looks up the pivot and tells if an undertaking should still be protected or no longer
Add two more columns to fashioned table to tell height time and modified time. this can support us in rearranging and sorting the facts. Modified time just strikes time by means of three hours (Henrik’s chart is plotted from 3AM to 3AM). At this stage our facts feels like this:
Now, pivot the facts once once again. This time,
exclude activities by using record filter on consist of? column.
set up top and endeavor in row labels enviornment, modified time in column labels enviornment and p in values enviornment.
organize the report in tabular structure, flip off sub-totals.
We get this:
Calculate normalized values by means of dividing every p price with maximum p value for that pastime. we are able to use a further latitude of 28×288 cells to do this. We get this:
The next 2 steps can also look puzzling. it will turn into clear once you appear at the charts.
outline an offset price. beginning with 0.5. which you can alternate this later. In a separate 28×288 phone range, calculate gaps by way of multiplying offset with place of an recreation. some thing like this:
Now, at last calculate activity + hole values by way of adding up respective cells in every of the 28×288 tiers. We get this:
At this stage, our statistics is a shape ready for visualizing.
creating and formatting overlapped enviornment chart
The chart creation process has 5 steps.
choose the 28×288 latitude of cells created in step 7 and insert an overlapped enviornment chart.
Now, reproduction the gaps latitude (created in step 6 above) and paste them on to enviornment chart as new collection (just ctrl+c your statistics and select the chart, press ctrl+v)
alter the order of sequence so that every pastime is sandwiched by accurately named hole sequence
Tip: adjusting fifty six series is painful with the chart select records > stream sequence up/down buttons. in its place, simply select the collection, analyze system bar. The series formulation has final parameter as order. alternate this number. it is handy to determine the number once you try a couple of.
exchange all gap collection fill colour to white. This straight creates the floating enviornment chart impact.
alternate the colorations of undertaking sequence. follow white / off-white border to those sequence. Your joyplot is equipped.
short overview of the chart advent manner:
Let’s assess the outcome of every these 5 steps with a smaller dataset so that you can see how everything matches collectively. right here is the records for this example:
Create an overlapped enviornment chart with activity+gaps information. We get this:
Add gaps as new series to chart. You get this:
movement the hole series in order that they sandwich undertaking sequence. Use Chart records > movement sequence up/down buttons or collection components
observe white color fill formatting for gap sequence. This creates floating area chart effect as below:
finally, format the chart by way of practice some colours and border formatting and so on.
So there you go. The final outcomes does appear happy.
alternate options to Joyplot
while joyplot is remarkable, it is not handy to make. happily, there are a number of less complicated alternatives that we can whip up in Excel as quickly as you've got both the pivot or normalized values. under I even have shown two such examples. read about sparklines or conditional formatting heatmaps for more.
Joyplot choice – the usage of sparklines:
Tip: to get axis for your sparkline, simply class the instances separated by a single house. Then go to layout phone (ctrl+1) and set horizontal alignment to dispensed. Viola, Excel will fill the cell by adjusting areas.

download Joyplot Workbook
click here to download Joyplot Excel workbook. determine the records scrubbing formulas, pivot and chart settings to learn how here is created.
if you're typical with R, then go thru Henrik’s R code. it's much shorter than the Excel gymnastics we did with circular pivot table referencing. That noted, one of the most statistics re-association may well be executed with same ease in vigour query too.
Your ideas on Joyplot?
The best step we missed in Excel implementation is relocating typical smoothing of the enviornment charts. It will also be without problems delivered as a step between 3 and four in statistics stage.
