Highest and lowest axis ticks not meeting axis line

[martyvd]

The highest and lowest y-axis ticks on my graph are not meeting the axis line properly. See my yaxis code and pictures below. I am using SGPLOT.

yaxis label='Percent of all admissions aged 12 years and older' VALUES = (0 TO 50 BY 10) tickvalueformat=data labelattrs=(family=Arial size=8) offsetmax=0 offsetmin=0 
thresholdmin=1 thresholdmax=1 valueattrs=(family=Arial size=8);

It is a good idea to share some data that will recreate the issue and show the entire procedure code.

Instructions here: https://communities.sas.com/t5/SAS-Communities-Library/How-to-create-a-data-step-version-of-your-dat... will show how to turn an existing SAS data set into data step code that can be pasted into a forum code box using the </> icon or attached as text to show exactly what you have and that we can test code against.

Provide all ODS graphics options that are also in effect when the program is run.

Since this is an appearance issue which ODS destination are you sending the output to?

In some cases some resolution of monitor/graphic file type and DPI settings can cause things not to appear to align at some viewing resolutions.

The output destination is PDF. See my full code below. I've also attached my data.

It could be that antialiassing has been turned off. This happens when there are more than 4000 elements to draw in a plot. You can ask for a higher limit in the ODS GRAPHICS statement with option

ANTIALIASMAX= 100000

[martyvd]

Adding this option does not seem to make any difference.

Either suppress the tickmarks or use the accepted solution (inside ticks), both shown here

If you do keep the status quo, I don't believe anybody will even notice the tick lines not matching at the joint
