Consider the following two images. Both use the same code, but are rendered differently. The first is the image that appears in the Plots panel in RStudio, and the second one is the image that appears in the corresponding knitted HTML document.
Observe the difference in the legends for the 'Below 0.1' label. Why has knitr rendered the document differently and replaced the black colour with the grey background colour of the plot in this legend label? (I realise there are no values below 0.1 hence they are 'missing', but I specifically want the legend label to still appear even when such values are missing.)
My code is at: https://github.com/a-s-russo/austemp In particular, see the weather_graphs.html file in the pipeline branch which produces the knitr image above. The RStudio image above can be reproduced by installing the package as per the instructions on the main branch page (or see first three code lines below). Both images are created using the following call to plot_temperatures():
> devtools::install_github("a-s-russo/austemp")
> library(austemp)
> data('Sydney')
> plot_temperatures(data = Sydney, season = 'winter')
(NB: ignore the image size differences. That's simply because of how I resized and saved them for the purpose of creating this question.)
