plot min/max values on legend

[mitchTwoTimes]

Hello,

It seems like plotEmbedding() is a wrapper to generate a ggplot. If I want to colorBy my GeneExpressionMatrix, how would I manipulate this object to only plot the minimum and maximum values in the legend? I would like to do something like this but am not sure how to interact with the values.

Thank you

I believe you are looking for the colorLimits parameter. You would have to determine the min and max values from the matrix and then pass them to colorLimits

colorLimits	A numeric vector of two values indicating the lower and upper bounds of colors if numeric. Values beyond these limits are thresholded.
