Axis category ordering - adds feature #189 #419

monfera · 2016-04-13T09:07:19Z

Original PR within downstream repo, with comments and historical commits: monfera#1

Implement axis attributes categorymode and categorylist to allow control of axis tick ordering independent of the trace order. See the attribute documentation, added Jasmine test cases and image tests for the API addition.

src/plots/cartesian/layout_attributes.js

+    categorymode: {
+        valType: 'enumerated',
+        values: [
+            'trace', 'category ascending', 'category descending', 'array'


@cldougl @chriddyp does ⏫ look ok to you?

👍 for me

Maybe we should include truncated versions of those values as well e.g. 'cat asc', 'cat des' ?

I'd suggest avoiding muti-word strings. Maybe just ascending and descending?

for me just ascending`descendingdoesn't have a clear relation to _alpha_numeric ordering. I definitely understand the aversion to multi-word strings, but I would vote for more description thanascending\descending`

plus if 'value ascending' \ 'value descending' are going to be implemented eventually

but I gotta say, catergoryorder doesn't sound bad at all.

You can add them as labels to the axes (currently described as ticktext) or use them as data (currently described as x). Given that the axis.type is category, one might think that categories is how you would add data to that axis.

and maybe categoryarray instead of categorylist

@chriddyp we're already using the value 'array' for tickmode.

You can add them as labels to the axes

More like: categories are added automatically. Categories have no effect on ticktext.

Given that the axis.type is category, one might think that categories is how you would add data to that axis.

Great point 👍

That's why I'm thinking that categoryorder might be the winner here.

@monfera we should also add one scatter3d test (similar to http://codepen.io/etpinard/pen/VaXmPx) showcasing one categorymode setting.

etpinard · 2016-04-14T20:17:45Z

@monfera

@chriddyp and I settled on categoryorder in place of categorymode and categoryarray in place of categorylist,

@monfera @cldougl @mdtusz any objections?

cldougl · 2016-04-14T20:18:46Z

👍 all good for me

monfera · 2016-04-15T03:20:11Z

@etpinard @chriddyp categoryorder and categoryarray are fine.

etpinard · 2016-04-18T20:29:38Z

@monfera Awesome work. 🍻

bmcole · 2016-06-13T21:17:54Z

Can someone provide an example (or point me to one) on how to use categoryorder = 'array' and categoryarray in order to manually specify the ordering of a categorical feature for plotting purposes with plotly? I can't find any online and all of my attempts in R have not worked. Any help would be appreciated

monfera · 2016-06-13T21:28:44Z

@bmcole I suppose you looked into the examples in the PR, but on the off chance not yet, just search for 'test' here, below the images: https://github.com/plotly/plotly.js/pull/419/files

bmcole · 2016-06-13T21:38:04Z

I found the test examples with json code, but am still unsure of how to
implement in R. here's my code that isn't working (it plots the order as
Friday, Monday, Saturday, Sunday, Thursday, Tuesday, Wednesday which is
undesired.

xform <- list(title = "Weekday",
               b = 150,
               tickangle=270,
               ticklen = 5,
               tickwidth = 2,
               categoryorder = "array",
               categoryarray = c("Sunday" , "Monday",

"Tuesday","Wednesday","Thursday", "Friday", "Saturday"))

yform <- list( title = "Number of Crimes",
               ticklen = 5,
               tickwidth = 2)

# line + scatter plot
plot_ly(weekdata, x = DayOfWeek, y = totalCrimes, type = "scatter",
        mode = "markers+lines", color = Category)  %>%

layout(xaxis=xform, yaxis=yform)

@bmcole I wonder if it's a date type related mismatch. Have you had any success with simple (non-date) strings or e.g. integer values? I don't have R in front of me right now but it may be a thing to try.

@bmcole categoryorder was added in v1.10.2 of plotly.js and the R package is currently using v1.10.1. I'll update our plotly.js version ASAP.
