Hi All,
I have a problem to manipulate the data list. Here are example of data in csv format:
1 1
2 -
3 -
4 -
5 4
6 5
7 6
8 -
9 7
10 8
11 -
12 -
13 10
From the data list, i suppose to draw line according to data by row. For better understanding, I attached the roughly drawing to describe my need. If refer to data square1 connect to circle1, square5 to circle4, square6 to circle5... But the problem here is the circles with "-" value in csv file. Example square2, square3 and square4 which connect to 3 different points between circle1 and circle4. How to get the different points refer to the total of "-" at the time? (3 points between circle1 and circle4, 1 point between circle6 and circle7, 2 points between circle8 and circle10). Then the line should be drawn from square to point according to data in row. Thanks.
