TProfile2D strange output

ROOT
#1

Dear All

I have created TProfile2D and filled it, but output is so unexpected.

Please tell me what should I do to delete this big orange “triangles”.
The profile have been created by below source code

[code]double diff;
FILE *file;
TProfile2D *profil=new TProfile2D(“diffAVR profil”,“diffAvr profil”,84,.0,105.,64,.0,64.);
// not important
for(int i=0;i<84;i++){

	for(int j=0;j<64;j++){
		for(int k=j*32+2;k<(j+1)*32;k++){
			// not important 
		if(i<42){
			profil->Fill(i,j,diff);
			fprintf(file,"i<42=%d\tj=%d\tdiff=%lf\n",i,j,diff);
			
		}else{
			profil->Fill(i+22,j,diff);
			fprintf(file,"i=%d\tj=%d\tdiff=%lf\n",i+22,j,diff);
		}
		
	}
	
}[/code]

Can you try to plot your histogram using COLZ ?
