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')
