311116 - Pie and Bar Chart Templates should have standardized dclrs parameter like Line template

The report.line.png.tmpl has the dclrs parameter that clues GD to use more than
the 7 default colors when creating plots with more than 7 datasets.

This should also be done for Pie and Bar charts.

In addition, the team should consider using a standard colorset that lends
itself to all Chart Types for consistency.

The colors used for the line chart is OK:
dclrs             => ["lred", "lgreen", "lblue", "lyellow",
                                  "lpurple", "lorange", "black", "green",
                                  "blue", "dpink", "lbrown", "gray",
                                  "red", "dpurple", "gold", "marine"])

However, using the same colors for Pie and Bar Charts won't work since black 
will be a fill color and blot out the labels.

Perhaps, replace black with cyan?

Attachment: Dashboard view and example of consistent colors across chart types

Folks,
To satisfy management types, I have a cron job that produces these charts
that's displayed on the home page of our Issue-Tracker.

As you can see, having consistent colors across chart types is really helpful.

Sounds sensible.

this is close to bug 311129 but it seems like you would need to pick one way or the other. Is there any way one of these could be targetted to 2.24?
