Code for formatting axes in graphs

[Sarah Haynes]

Hello,

I have a neat little graph showing each day for each participant in my study. I have created this graph using the following code (you can run using dataex data below). I am having trouble doing something simple: limiting the x axis to 180, and including tick marks on the x axis for every 10 days. I can easily do this in the graph editor by setting the range from 0 to 180 and the delta to 10 but can't figure out how to add this in the code. I tried (as you can see below) to include the code xsc(range(0 180)) but the x axis is still showing 0-200. Hopefully I'm just missing something small?

Thank you!

Sarah

The data example doesn't extend beyond day == 100 and you don't show your graph. So I have to guess at the problem here.. The help for axis scale options explains that

range() never narrows the scale of an axis or causes data to be omitted from the plot.

and this is the usual explanation for why it is ignored. So, what is the maximum value for day? xscale() will never obey a range() suboption call that includes a maximum less than the observed maximum.

On the other hand

xla(0(10)180)

should give labelled tick marks every 10 from 0 to 180. I would be more likely to go

xla(0(20)180) xtick(10(20)170)

Hi Nick! Sorry about that. Here is my graph - the maximum value is 180 so it's not a matter of omitting data.

[Sarah Haynes]

Oops I see the graph that I copied didn't come through- I attached it here.

[Sarah Haynes]

Sorry that line of code you sent worked- apologies for all of the posts!

[Nick Cox]

The graph helps -- but please note the request to show .png not .gph (FAQ Advice #12).

Knowing that the maximum value of day is 180 permits a better story. There is no connection between xsc() and xla() and you needed to tune xlabel() directly to get different labels.

I would

use scheme(s1color) or some other scheme or otherwise lose the blue backdrop

plot deceased by no colour at all, not a funereal black

use yla(1 5 10 15, ang(h)) unless naturally you do have patient 0
