Root Color Wheel visualization problem


I hope I have posted in correct forum, kindly correct me if I am wrong. I am using root version ‘ROOT 5.34/32’ in Ubuntu ‘14.04 LTS’. Suddenly I got a problem in visualizing root color wheel. Kindly have a look at the attachment.

I have tried to change root version also as I do not know whether it is related to root or something else. But it is not working still. Kindly suggest me what to do.

Thanks in advance,

Ha yes … the color wheel is not a wheel any more in your case … :slight_smile:

Which commands are you typing exactly ?
