How do I remove NaN's from my data?

I was given a csv file and I used this code below to read it:
clear;
fclose all;
fileID = fopen('accidents_2017.csv');
text1 = textscan(fileID,'%s%s%s%s%s%s%d%d%s%d%d%d%d%f%f','HeaderLines',1,'Delimiter',{','},'EmptyValue',NaN);
fclose(fileID);
How do I plot this data? My teacher never gave a function of how to plot with data values. I already converted all the data into numbers using str2double(text1). What should I do?

If your numeric vector is called "x", then
x(isnan(x)) = [];
will remove the NaN values.

As this is roughly the 4th or 5th posting on the same topic:
as far as I have been able to determined, this is an assignment and the poster is required to use textscan() with the format indicated, even though it is not the best tool.

Don't use
str2double(text1)
Use
str2double(text1{1})
replacing the 1 with 2, 3, 4, 5, 6, or 9 as needed (the column number to extract.)
