I want to plot data from .xlsx (or .csv) file. I have used the following code. earlier I had also used round braces in line 2 and 3 but that didn't work as well. It gave the error message "Tables and timetables do not have a plot method. To plot a table or a timetable, use the stackedplot function. As an alternative, extract table or timetable variables using dot or brace subscripting, and then pass the variables as input arguments to the plot function." After using curly braces now the error message is "Error using plot Invalid data argument." The data file has around 2 Million *22 enteries. Any function that converts it into a matrix would be helpful. Thanks in advance
T =readtable('PuneAQMNew_22.xlsx');
Time=T{:,16};
AirQuality= T{:,2};
plot(AirQuality,Time,'r')
legend('Airquality')

I have csv and xlsx files for the same data. If I use the csv file the script runs fine whereas it shows the errors mentioned above for the xlsx files. The class type of Air Quality is double and time is duration in the csv file.

Please attach a short extract of the file, including any headers that are present.
