Graph options for connected line graph (two y-variables) only apply to one y-variable

[Pierre Kind]

Hello,

First time using datex. Hope this output is fine for you.

I'm trying to create a twoway connected graph with with two y variables (lower_limit and bigger_limit) and one x variable (bin). The two y variables where created by using:

gen lower_limit = change if bin < 4750 & bin > 2000
gen bigger_limit =  change if bin > 5250

The question I have now is, I want the connect points for both y variables to have the "diamond-style". But whenever I use

twoway connected lower_limit bigger_limit bin if bin != 5000 & bin > 2000, msymbol(D) xlabel(2500(500)7500) xtitle("") xlabel(3000 "3000" 4000 "4000" 5000 "5000" 6000 "6000" 7000 "7000") ylabel(.30(.10)0.7) ytitle("") xline(5000) color(red) title("") || lfit lower_limit bin, lcolor(red) lpattern(dash) || lfit bigger_limit bin, lcolor(brown) lpattern(dash)

msymbol(D), it always applies the diamonds only to lower_limit connection points not for the connection points from bigger_limit. Also same problem applies to color(red). It only colors the lower_limit. I cannot figure out how to apply for both. Couldnt find anything about in the options.

Hope someone can help.

I have also complained about this not being documented in the past, but to no avail. With such graphs, you want to repeat the options (or specify each option independently).

twoway connected lower_limit bigger_limit bin if bin != 5000 & bin > 2000, msymbol(DD)

[Pierre Kind]

Hello,

thank you for your answer. Trying msymbol(DD) gave me unfortunately this error message though:
"(note: named style DD not found in class symbol, default attributes used)"

Sidenote: Im using Jupyter Notebooks with Stata Kernels. I wouldnt see why this would matter, Im just giving this information in case it's necessary.

[Andrew Musau]

Can you post the data in #1 again. Make sure to preview before posting so that everything is not on one line.

[Pierre Kind]

Hope it works now for you

The example is of limited use as lower_limit bigger_limit are always missing. But the issue is easy to explain.

You can run this code in your Stata, unless you are behind a very strict firewall. Even if you can't run it, it explains.

* you should be read this in as a sandbox 
. webuse grunfeld, clear

* the default symbol for connect is a solid or filled circle 

. twoway connect invest mvalue year if company == 1

* specify D and the first named variable is plotted with a diamond; the second is plotted with the default 

. twoway connect invest mvalue year if company == 1, ms(D)

* specify D D and the first and second named variables are plotted with diamonds 

. twoway connect invest mvalue year if company == 1, ms(D D)

* Andrew forgot briefly about the need for a space 

. twoway connect invest mvalue year if company == 1, ms(DD)
(note:  named style DD not found in class symbol, default attributes used)

* ms(D) does not mean "all variables should be plotted with diamonds"; there is a syntax for that 
. twoway connect invest mvalue year if company == 1, ms(D ..)

For once I disagree with Andrew Musau. This is documented, at

help stylelists

[Pierre Kind]

It worked. Using (D D) made both variables have diamonds. Thank you Mr. Musau and Mr. Cox

[Andrew Musau]

Thanks Nick Cox for the correction and the reference. I completely missed that entry in the documentation.

[Nick Cox]

The ideal manual is one paragraph long and includes just the information you need at this particular instant.
