FR: Avoid manual update for the caption of time profile plot

[IndrajeetPatil]

It's not clear to me as to why, but, the caption for tlf::plotTimeProfile() output needs to be manually updated using setLegendCaption(). This is quite tricky and error-prone.

Is there any way that this is internally handled by the plotting function itself?

It is a bit surprising that the caption is not automatically updated to the chosen mappings for the plot, and needs to be updated manually.

Agreed.

@IndrajeetPatil
Not sure I understand what you mean there, can you add an example ?

[IndrajeetPatil]

Sure.

Not sure if you remember, but we had this issue where instead of each group getting its own color, the same colors were being recycled. This is why we added this function that updates caption legend data frame.

Here are outputs from this test that illustrate the point.

(Note that there are only 3 unique colors which are used twice in the caption and the plot when there are 6 groups)
