# Transform table values into variable

Hello!
I have a 4x33 table (4 participants and 33 variables). Now I want to:
• make plots/histgram for just one participant at a time
• for the x-axis, take 3 values (from 3 different variables, although they all measure RT (reaction time)
• for the y-axis, take 3 values (from 3 different variable, they all measure true positives in task).
I extracted two subtables:
T1 = LNBtableS1(1:1,[21 24 27])
T2 = LNBtableS1(1:1,[19 22 25])
How can I combine them in either one table that I then can plot a histogram from, OR convert the three values of T1 and T2 into two variables that I can then combine in a histogram?
Many thanks!
Marianne

Hi Marianne ,
You can solve using the JOIN function as Sai Sri mentioned in answer or you can also do this
var = LNBtableS1.Variables;
x = var(1,[21 24 27]);%x will contain values needed for x axis
y = var(1,[19 22 25]);%y will contain the values needed for y axis
plot(x,y);
This create plot for first participant and similarly you can do this for all participant.

You may use join function to combine two tables.
Here is the link to documentation of join function: https://in.mathworks.com/help/matlab/ref/table.join.html
