Hi,
I see two possible things that would get wrong, both linked to the style
of color/pattern applied to your graduated classes :
1) Check what is the other values color (from the style button). Is your
other color black ? If it is, then change it to another color. If it
changes and take the new color, then some of your values are out of range
or aren't read correctly, they aren't recognized as numbers (check what
character you are using as separators for decimal points or for
thousands). Solution : correct the data in your table.
2) Check the style applied to the different ranges of values : did you
use plain and solid colors ? or did you use front and background colors ?
in some cases, if the front color used as pattern is too dense your
screen or printer may display everything black. Solution : change your
pattern..
I hope this help.

Objet : MI-L Graduated and colour range - Previous different sized
symbols
Hi Listers,
I am trying to map a group of 97 points, by individual value (colour) and
value range (size). The application is mapping the cost of a healthy food
basket by median household weekly income by locality.
I have tried to implement Stuart Morrison's solution (message # 15885 in
archive) to Christine Ronning's problem, namely to do two thematic maps on
the one dataset to achieve symbols that vary by colour and size.
I have followed Stuart's instructions and have constructed an individual
thematic on my dataset prior to and below the graduated thematic, but find
that many of my points, with different variable values, are appearing
coloured in as Black. To add to the curiosity, there is no black cohort in
the individual value legend.
I have ensured that I have the size option selected instead of all
attributes in the 'apply' box in the bottom right hand corner of the
ranged theme>modify thematic map>styles dialogue (as opposed to all
attributes).
I am using MI7.0 on WinXP.
In the words of an Australian political non-luminary "Please explain".
If you can see what i'm doing wrong, please let me know.
Cheers,
Alistair.
