Draw line of chart and collect information

Hello guys,

I need your help on 2 separate scripts:

1.     On a plain chart, I have color vertical line. I want to collect time and date for each vertical line (bar 0) and 3 bar prior to it (bar -1,-2.-3)

The output file in scv should be:

Bar 0_date        Bar0_time         Bar0_Color_code                    bar -1               bar -2 bar-3

There are 6 colors of the vertical line and I should be able to assign code (in output file) for each color.

---------------------

2.     I have a scv file the following setting:

Date                     Time                              Long_Short        Color

2012.05.06         12:00                                 1                      2

.....

..... 

 Long_short has 2 possible value: 1/0 (1 Long and 0 short)

Color have value: 1,2,3,4,5,6

I want to draw a vertical line on charts for each time and date.

I should be able to choose whether line draw for only a supset of the data based on Long_short and color. For example, draw only Long (code 1) and color code 2. 

I should be able to assign color to each value.

That's all.

Thank you,

 HHC
