What is the expected interpretation of
09276215;0;;;;;;;;
3943927;-3
Your column 1 is all 0 until row 1264, and column 2 has leading digits that are increasing up to that point. Then at row 1264 column 1 becomes 1 and the leading digit of column 2 goes back to 0. It looks to me as if column 1 and column 2 together form a number.
Question: has this been produced on a system that uses comma as a decimal separator, and semicolon as the field separator?

S = fileread('myData.csv');
S(S==',') = '.';
data = cell2mat( textscan(S, repmat('%f', 1, 11), 'Delimiter', ';', 'headerlines', 1));
plot(data(:,2), data(:,3));
