I would like to draw a graph with the import of the date in abscisse

Hello everyone, I would like to draw a graph with abscisse the date. I have a file that is composed like this: column 1 line number, column 2 day, column 3 months, column 4 years, column 5 hours, column 6 minutes, column 7 seconds, column 8 point number, column 9 coordinates EST, column 10 coordinates North and column 11 coordinates altitude. I would already like to draw a graph with the GNSS1 number for example and the east coordinates according to the dates. And I don't know how to import the dates into Matlab

Hi,

You can use import tool to import the data. Import it as a table. You can set the column names while importing.

You can extract the data from the table as follows.

indices=table.VarName8=='GNSS1'  % getting the row numbers of the table with 8th column as 'GNSS1'

X=table.VarName1(indices);       % extracting 1st column to a variable X
Y=table.VarName2(indices);       % extracting 2nd column to a variable Y

You can use plot function to plot the data.

plot(X,Y);              % plotting 2nd column data against the first column data

Hope this helps.
