半对数图请指教

先讲下数据结构。纵坐标为药物浓度concn[0-250]，横坐标为时间days[0-100]。
要画半对数图，其中纵坐标浓度要用4 40 400（三者之间是等距的）。
小弟尝试用sgplot画。
yaxis type=log logbase=10 logstyle=logexpand
日志报错，查帮助选项只用于xaxis。
于是换sgpanel。生成的纵坐标是10 50 100，跟预期不符，不知怎么设置参数。
请大神帮忙解答，小弟感激不尽！

1. proc sgpanel data=tmp;
   
2.         panelby drugid /noborder novarname onepanel  START=BOTTOMLEFT;
   
3.         rowaxis type=log logbase=10 logstyle=logexpand ;
   
4.         series y=concn x=days/ markers lineattrs=(thickness=2 color=blue)
   
5.         markerattrs=(symbol=circlefilled color=blue);
   
6.         keylegend  / noborder DOWN=2 TITLE='Conc vs days'  position=right;
   
7. run;

I usually use gplot. In this case I'd try the following axis definition:

Axis logbase=10 order=(4 40 400).

Proc gplot .... ;
Plot .... / yaxis =axis1;
Run;

sgplot中yaxis可以用type=log等选项，但是纵坐标仍然是10 50 100

Thanks for your suggestion.

Actually, there is no 4*10E(0 1 2 3). SAS support logbase=10 just as (1 10 100 1000).

I try to use max=1000 in yaxis while it works.

Now here is another problem .

A graph has more than eighty group.I plot such many series but there if no space to export so many legends. Which option can solve this problem ?
