All,
I am sorry to bother you again about this, but I really need some help...=20
Is there any other place where I can look for help ? like a bug reporting=20
or a list where I can talk to the reportlab developers ?
Thanks a lot,
Marcus

This code actually generates the chart with the black lines I told... I
don't know how to fix it !!!<br><br>
The data list is a list of lists... this was the only way I found to
change the color of each bar instead of having the bars in only one
color... If I use data with just one list then I receive an error telling
me that there was just one data in the data series but was expecting
14... And then, I have to make the labs list as a list containing another
list and this one with the 14 labels regarding to the data series... and
this generates an equal chart, but this chart has just one color, and if
I try to change the color for each bar, all bars will have the same color
of the last bar I have changed its color...<br><br>
I am trying to attach the actual jpg of the problem so you can better
understand the problem I am telling.<br><br>
I would appreciate any help !<br><br>
Thanks,<br><br>
Marcus<br><br>
