column1    column2
data1    data1

data3    data3
data4    data4
data5    data5
data6    data6
data7    data7
data8    data8

so the problem is how to create chart which for x axis has column1 (but the number of rows in column one is variable)and the number of lines is the number of tables(data in the tables).

hope this brightens the problem.
