Use greek letter in graph legend

[xxz3231]

Hello,everyone,

I want to build  a simple scatter plot, I need to including greek letter in the legend,for instance,

X    Y     Treatment

1     11       T1

2     12       T1

3     13      T1

4     14      T1

5      15     T1

1     21       T2

2     22       T2

3     23      T2

4     24      T2

5      25     T2

1     31       T3

2     32       T3

3     33      T3

4     34      T3

5      35     T3

What I need is for each treatment's lengend ----TRT 'delta'Quantity ('mu' ('plus/minus')90% confidence interval)

Would you please give me some ideas about how to generate "delta" "mu" and 'plus/minus' in the legend?

Thank you very much!

Read this article about using Unicode by Dan Heath. The last example shows how to use Greek letters in an inset, which is similar to a legend.  The GTL doc has information about how to specify UNICODE strings and also includes a table of common unicode values such as Greek letters.
