I am having the same problem, I am working with a heatmap and I want to put some annotations, those annotations should be located in a specific position relative to a cell or column of my chart, the question is how can I do that? I saw some examples but they are so simple, there is no one that resolves something similar to what I have intended to do, and there is no documentation about this neither, I want to know the full syntax to use the macros for example, if I have $dataset.0.set.2.x I want to know what means the "0" and the "2" in the expression.
Does"$dataset" something to do with the "dataset" in the chart structure ?
Please respond.
Thank you.
