Yes, I showed those in my last e-mail. As far as I know 
this part seems to work fine.
they are as follows:

  [displayActions createActionTo: distGraph           message: M(reset)];
  [displayActions createActionTo: distGraph           message: M(update)];
  [displayActions createActionTo: distGraph           message: M(output)];

Is this why the bars seem to be out of alignment from the 
bins in the x-axis?

I'm aware of this. I hadn't realised setting it too large 
would upset EZBin !!! 


My main problem is the colour of the bars!!!
It occurs to me the bars on my graphs may be white (same as 
the background colour) and so appear invisible.
Looking at the source for EZBin I don't see a setColor 
method. If this is the reason why the bars are 'invisible', 
is there a way round this i.e. to set the colour some other 
way ?
