When describing changes of the E-field with distance, is it the 'Distribution of', 'Repartition of', 'Variation of' (or, simply) the Electric field?

–Unsure if this is a question for Physics or for language/English stackexchange, asking this in Physics as I assume more people here are familiar with these notions in scientific talk–

I have a 2D figure (labeled ‘Figure 1’) that represents the discrete values of the Electric field E (on the ordinate) at different points along the x-axis (the abscissa) between, say, 0 and 0.6 mm (representing the thickness of a sample).

I want to describe this figure. How should I go about it?

1. Figure 1 presents the distribution of the Electric field with the depth of the sample
2. Figure 1 presents the repartition of the Electric field with the depth of the sample
3. Figure 1 presents the variation of the Electric field with the depth of the sample
4. Figure 1 presents the Electric field with the depth of the sample

So far, I’ve received feedback that:

• Distribution is more about statistics, and how often a value appears in a set data (like histogram plots)
• Variation is more about the changes of the values from a known initial value (and not changes of a variable with distance)

Yet I’ve found both the first and the second in scientific papers (for example, ‘the distribution of temperature T(x) with x…’ or ‘the variation of the Electric field E(r) with r …’) . I also found the ‘repartition of the Electric field E(x) with x, but it has only a fraction of the results I found for the other two.

How is most common to describe the changes of the Electric field with the distance/depth in that Figure 1 presented above?
