hold on

or

set(gca, 'NextPlot', 'add')

in between your calls to plot or however you are plotting.

thanks Tommy, if the number of each column to much(about 1.300.000 row) how can i draw it?

[Tommy]

Can you provide all of your code? I'm thinking a bit more context could be useful.

Thank Tommy, here is my code, can you help me! newdata is about 1 column and 1.300.000 rows

[clearData,outlierIndices]=rmoutliers(Databbase);

Newdata=table2array(clearData)

A=Newdata(:,1);

plot(A,'m-')

[Tommy]

Ok thank you. What are you hoping the plot will look like? Your vector is so long that it is impossible to see any of the background which would make it easier to see the actual values being plotted. Similar to the following:

plot(rand(1000000,1))

Do you no longer have two columns to plot?
