How to control the increment of the labels from psscale

  

Dear all 

I am attaching a map showing a logarithmic scale. 

I
had to lower the font size because the labels overlapped. 

I had tried,
for example, 2.3 = log(200), but psscale accepts integer values only.


Is there an option of psscale to control the increment of labels on a
logarithmic scale, please ? 

Thanks for your help
