Here, color clrCyan has index "0", clrRed has index "1", and so on.

Management of histogram colors is implemented by assigning an individual color index to each index of the HistogramColors buffer:

switch(STime.day_of_week)
        {
         case  0:
            HistogramBuffer[i]=0;
            HistogramColors[i]=0;
            break;
         case  1:
            HistogramBuffer[i]=1;
            HistogramColors[i]=1;
            break;
         case  2:
            HistogramBuffer[i]=2;
            HistogramColors[i]=2;
            break;
         case  3:
            HistogramBuffer[i]=3;
            HistogramColors[i]=3;
            break;
         case  4:
            HistogramBuffer[i]=4;
            HistogramColors[i]=4;
            break;
         case  5:
            HistogramBuffer[i]=5;
            HistogramColors[i]=5;
            break;
         case  6:
            HistogramBuffer[i]=6;
            HistogramColors[i]=6;
            break;
