I have this file I've made in 2007, which doesn't display correctly the format of y axis labels. The format should be exponents.
Comment 1 Andreas J. Guelzow 2012-10-19 18:56:20 UTC 
The format #.00EE0 is no longer recognized. Apparently one now has
#.00EE00 or #.00EE+0
Note that the former incorrectly renders as 3.14x10^0 ie. with only a single digit in the exponent.
Comment 2 Morten Welinder 2012-10-20 00:26:28 UTC 
Looking at #.00EE00 first.

We're compiling it wrong.  We generate this for #.00EE00

...
OP_NUM_PRINTF_F 0
OP_NUM_SIGN
OP_NUM_EXPONENT_SIGN 0
OP_NUM_MOVETO_ONES
OP_NUM_STORE_POS
OP_NUM_DIGIT_1 '0'                       <-- One only
OP_NUM_REST_WHOLE
OP_NUM_APPEND_MODE
OP_NUM_SIMPLIFY_MARKUP_MANTISSA

whereas for #.00E+00 (single-E) we generate

...
OP_NUM_PRINTF_F 0
OP_NUM_SIGN
OP_NUM_EXPONENT_SIGN 1
OP_NUM_MOVETO_ONES
OP_NUM_STORE_POS
OP_NUM_DIGIT_1 '0'                       <-- Two!
OP_NUM_DIGIT_1 '0'
OP_NUM_REST_WHOLE
OP_NUM_APPEND_MODE

Tentative patch

We need some kind of tests for this.
