sgplot template

Hi, when I tried to generate a sgplot using the macro below, here I separated the plot to 3 different areas.  When the lower band (lower) locate in both middle and bottom areas (across the -15 on y axis), on the top of area3 (<-15) also showed a red line as pasted below even if the real Y values are not located in that area. Is any way to correct this display to show the red line plot as it is?

 

Thank you!

Re: sgplot template

That's next to impossible to debug.  First off, can't see any data.

 

As a suggestion I would read up on proc template and dynamic variables. The macro here is not needed an obfuscates the code a lot, for instance;

 

goptions reset=all;

ods graphics/ imagemap=on width=7in Height=6in ;

proc template;
  define statgraph sgplot1;
  begingraph;

  dynamic biasarea biaw;

  layout lattice / rows=biasarea rowweights=(biaw) rowdatarange=union rowgutter=2 columndatarange=unionall;
...

run;

proc sgrender...;
  dynamic biasarea=3 biaw=".2 .6 .2";
run; 



Note also the use of the code window (its the {i} above post area) which retains formatting and such like and makes code easier to read.

Re: sgplot template

Thank you very much for your quick reply and apologize the code is not listed as formatted. The issue is when the area selected to be 3, the bottom area would display the curve that would be not expected. If I follow your dynamic setting, probably I still could not resolve this issue?

Re: sgplot template

Provide some sample of your data. Makes it much easier to test your code and help you Smiley Happy

Re: sgplot template

Hi Draycut,

 

Thank you. I just created a data as attached. And I also used my lengthy code to run it, surprisingly, I got the plot as expected. However, the same data in the enterprise guild would give the plot. So it must be the running environment cause the display difference? 

 

Thank you!

When running in the enterprise guide previously the disply looks (the bottom red line is not as expected):

Re: sgplot template

Hi draycut,

 

Please ignore my previous post. It may be not worthy to look at this long code and compare between the sas pc and enterprise guide. So please do not spend time on this and ignore this posted issue.

 

Thanks again!

Re: sgplot template

As noted in my previous post, there are some things to do with your code which will make your life a lot easier, and people who have to look at you code:

First don't code all in mixed case - it sounds like shouting and makes the code hard to read.

Use indentations to show where blocks start/end.

In the datastep, you can use a select () clause to simplify that datastep

Thirdly, use macro variables only when needed.  In your example they are not needed, refer to the code I posted with dynamic variables, this again will halve the size of your proc template code by removing all the macro nonsense.
