hi i have a problem with the graphic, i need to have different color for every differet vector in the code of bar graphic that i wrote.

the color are:

R_all=[Rrum=red,R2rum=yellow,R3rum=black,R4rum=green,R5rum=blue,R6rum=cyan,R7rum=magenta,R8rum=white]

Answer 1

Hi, it seems that you are trying to get different color for every different vector (e.g., Rrum=red, R2rum=yellow, R3rum=black, etc.) in a bar graph.

I have made some changes in your code to make it display different color for different vector. (Refer the attached script)
