problems in displaying reports of tickets

Hi,
I am trying to display reports of ticket.At the time of displaying reports for opened tickets i am not getting the chart based on colors,it is dividing with thin white line.If I removed priority and urgency for some tickets I am able to see only one color in chart. Can you please suggest how to display data separated with all colors in report based on give value.

The below attachment shows if I select few values for tickets only one color is displaying. Suggest me for all colors for all data.

Iam using 6.3.1 version of projeqtor, I have added so much of data in this version of projeqtor.Is it possible to modify any code for colors in chart?.

I dont find any option in tool to upgrade to 6.3.3. Is it possible to upgrade from front end.Or do i need to install new version again and use old database while installing.

When i installed new version of projeqtor by using old database(i have imported old data into new version database),I found something like this regarding reports not getting same colors what i mentioned in list of values.For some values getting same color.For example below urgency iam getting same blue color for "blocking and Not urgent" although I didnot mentioned blue color for both of them.
