NEED HELP about Swimmer Plot

Hi, I'm having trouble when I output Swimmer plot.

First question, I'd like to understand how to adjust the size of y-axis value or the line-width (x-axis is Week and y-axis is Subject No.) because it would not show all subject no. when the number bars is too many.

Second, there's an uneven color of each bar under option transparency=0.X when one subject has two or more events. I'd like to know how to resolve that issue if I still have to adjust the transparency of bars.

 

This is my first time to share questions here, please feel free to give me advice when you can.

 

proc sgplot data=final nocycleattrs;
highlow y=ptno low=low high=line_end / group=stage attrid=A type=bar fill nooutline transparency=0.5
        name='stage' barwidth=0.3;
highlow y=ptno low=crstart1 high=crend1 / group=Duration lineattrs=(thickness=2 pattern=solid)
  		lineattrs=(color=red) name='Duration' nomissinggroup attrid=Duration;

Hi John,

 

There are at least two solutions to help you to view each subject id.

 

One of them is to change the dimensions of the image, so that it is portrait instead of landscape. This will give you more space on the yaxis I can be done by simply changing the options within ods graphics (I modified Sanjay's earlier example):

 

ods graphics / reset imagename='Swimmer_portrait' height=6.67in width = 5in;

Another option, as Sanjay also said is to get rid of the labels on the y-axis and add the subjects labels at the end of the bar chart.

 

Swimmer_label.png

 

The following code, can help you achieve that: Basically the dataset has been updated to include the position where the subject labels should go, and then this label has been added to the end of the barchart using a new highlow statement - just because some of the start values, where after the end values.

 


* Make labels on bars;
data test2;
set test;
max_end = max(line_end, end1, end2, end3, start1, start2, start3);
label_x_axis = max_end + 0.1;
run;

ods listing gpath='C:\Users\yex7977\Communities\Image' image_dpi=200;
ods graphics / reset imagename='Swimmer_label';
title h=1 'Figure 1 : Summary Horizontal Bar Chart of Severity';
proc sgplot data=test2 nocycleattrs;
* label;
highlow y=No_ low=low high=label_x_axis / attrid=A type=bar lineattrs=(color=white) nofill outline transparency=0.5
name='drug' highlabel=No_;
highlow y=No_ low=low high=line_end / group=drug attrid=A type=bar fill nooutline transparency=0.5
name='drug';
highlow y=No_ low=start1 high=end1 / group=Duration lineattrs=(thickness=2 pattern=solid)

It is easier to help if you share everything needed to run your program, including data.  What release of SAS are you running?

Re: NEED HELP about Swimmer Plot

I got your program running.  In future it is better to attach SAS code for data too.

All your start values are zero.  So, if a subject has multiple events, they will overlap.  Either they need different start value, or you need to separate them into separate ids (113, 113A, 113B)..

You can use LabelPos=Top for putting y-axis label on top.

Re: NEED HELP about Swimmer Plot

Thank you, Sanjay. It is really helpful for me.

 

I set all start values as zero since this is my first time to generate Swimmer plot and also PROC SGPLOT.

In my point of view, 

highlow y=No_ low=low high=line_end / group=drug attrid=A type=bar fill nooutline transparency=0.5
        name='drug';

this code is to determine the starting point and the end of swimmer lane. And the "scatter" code is to mark the points on the lane.

So, it will become complicated by setting different start values. Although, separating ids (113, 113A, 113B).. is the way to resolve the overlapping, I need to show one person by one swimmer lane even if there're multiple events of him/ her. Is it possible?

Re: NEED HELP about Swimmer Plot

Sure.  Each lane is defined by a specific unique id.  For ids with multiple events, create unique ids like 113a, 113b, 113c, to get different lanes.  The label for each lane can be from another column, 'SubjId'.  The displayed label can be 113 for each of the 3 lanes.

 

So, you need a unique column, say ID.  Then you need another column say 'SubjId' which will contain the same value for all 3 values (113).  Then display the SubjId using "LowLabel" option in the Highlow plot.  Turn off the Y axis tick values.

 

highlow y=Id low=low high=line_end / group=drug attrid=A type=bar fill nooutline 
transparency=0.5 name='drug' lowlabel=SubjId; yaxis display=(novalues nolabel);

Re: NEED HELP about Swimmer Plot

Hi Sanjay,

 

Sorry for the late reply. I got the heavy workload recently.

Well, I've just tried the code you provided, but it cannot work and popped-out the error message as follows. Could you please help to resolve, thank you.

 

When I'm using "fitpolicy=none labelpos=top" at the same time:

未命名.png

 

If I'm using only "labelpos=top" to show the label of y-axis:

Besides, can I ask about the function of "nocycleattrs". Thank you very much.

Re: NEED HELP about Swimmer Plot

For the first question, I got the Note that FITPOLICY option has no effect if used with the vertical (Y or Y2) axes; only the THIN fit policy is used for vertical axes under SAS 9.3.
So...is there any better way to show every tick mark value on the y-axis?

Re: NEED HELP about Swimmer Plot

Hi djrisks,

Thanks for your answer! The first one is the better for me. Maybe the graphs would look like landscape if I larger the width!
However, another issue is unsolved due to an older release of SAS as Sanjay said. So, the "label pos=" option cannot work.
Besides, I use SAS 9.3.

Re: NEED HELP about Swimmer Plot

If some options are not compiling for you, that means you have an older release of SAS.

NOCYCLEATTRS means the colors (and other attributes) will not continue to use increasing group indexes into the attribute list.  For a graph that is built using multiple layers of "grouped" plots, it is better to explicitly control the colors using the Discrete Attributes Map.

Re: NEED HELP about Swimmer Plot

Okay, thanks for all your great help!
May I ask one more question? Is it possible to change the color of bars?
