Plotting a portion of a graph

If i have a vector of 200 values and I want to plot the values between 50 and 70, how to do so?

Very ambiguous so I guess I'll have to answer several potential cases.

To plot indexes between 50 and 70:

plot(vector(50:70), 'b*-');

To plot values of vector between 50 and 70 (i.e. the y values rather than the indexes):

indexesInRange = vector >= 50 & vector <= 70;
subVector = vector(indexesInRange);
plot(subVector, 'b*-');

If you have another vector x that is different than the indexes, for example you have a 100 indexes but x ranges from 0 to 5000, then

indexesInRange = x >= 50 & x <= 70;
subVector = vector(indexesInRange);
plot(subVector, 'b*-');

@Image Analyst, thank you, I mean the second case you mentioned i.e. (To plot values of vector between 50 and 70).

You're welcome. If we're done then could you mark the Answer as "Accepted"?

plot(vector(50:70))
