I have the suspicion that you might be attempting to plot variables in a table() object. No currently released version of MATLAB supports that directly; you would need to instead
plot(data.signalTime, data.signalNoise, '.')

The easiest way to specify the tick labels as strings is to use the xticklabels function. For example, plot five points. Change the ticks to only five values by calling the xticks function. Then change the x-axis tick labels to “x1”, “x2”, “x3”, “x4”, and “x5”. 
plot(1:5) 
xticks(1:5) 
xticklabels(["x1", "x2", "x3", "x4", "x5"]) 
Another way to combine a character with a sequence of numbers is to use the xtickformat function. 
plot(1:5) 
xticks(1:5) 
xtickformat("x %g ") 
Alternatively, you can plot categorical values. Specify the second argument when you call the “categorical” function to ensure that the data is in the expected order. 
x = categorical(["Red", "Yellow", "Blue"],["Red", "Yellow", "Blue"]);
plot(x,1:3)

What if we have large number of data points..say 70?
How can I then obtain a plot in matlab?
