No. It is independent of both.
See the link.
Notice in the definitions, for both the population and sample versions of the coefficient, that the numerator involves subtracting both means and the denominator provides for dividing by both standard deviations. This makes both coefficients location and scale invariant.

Is Coefficient of correlation is independent of change of origin and scale?
The Coeffecient of corelation is definitely independent of origina and scale. If r(x,y)= cof or cor b/w X and Y let W=aX+b and Z=cY+d then r(x,y)=r( W,Z) Note that adding or subtracting a constant in all values of a random variable changes its scale. While multiplication or division change scale. The Form W=aX+b, caters the change both in origin and scale.
What are the characteristics of proportional relationships?
Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
How Translating the point of origin?
Origin is at points (0, 0) in coordinate geometry. If you are shifting/translating the origin, you have to add the respective x and y coordinates of the new origin with respect to the old origin to get the coordinates of the new origin.
What are the coordinate of the origin?
(0,0) are the coordinate of the origin.
How do you rotate a figure about the origin?
The x,y origin is 0,0
How change of origin or scale effect value of co-efficient of co-relation?
The correlation coefficient is unaffected by change of origin or scale unless one of the sets of variables is multiplied by a negative term, in which case the correlation coefficient will become negative.
What Are The Properties Of Regression Coefficient?
(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity. (c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, provided r > 0. (d) Regression coefficients are independent of the changes of origin but not of scale.
Properties of regression coefficient-statistics?
8.7.4 Properties of Regression Coefficients:(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity.(c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, providedr > 0.(d) Regression coefficients are independent of the changes of origin but not of scale.

The production of Independent Movies goes back to the early years of film history. The first independent films were first considered American Independent films.
What is change of origin and change of scale?
Translation and dilation.
Is genetics a Latin word?
No, genetics is not a Latin word. It comes from the Ancient Greek word γενετικός genetikos, meaning 'genitive,' itself from the word γένεσις genesis, meaning 'origin.' The correlation between that and the Latin word gens, meaning 'tribe,' is independent of our English derivation.
