I am talking about adding the values of a qualitative variable, e.g. country codes, as labels. As an example from my megacity research, imagine a scatter plot of carbon footprint (y-axis) vs city population (x-axis). In such a plot, it would be very useful if the data points were labeled with the megacity name. So I am suggesting that two separate improvements be considered for gretl: (1) Add the capability of handling qualitative (i.e. text) variables, something that is sorely missing right now. I have to manually delete columns containing text from Excel files that I want to open in gretl, which is inconvenient. If anything else, gretl could ignore such columns, not give an error and refuse to open such a file. (2) Add the capability of adding a qualitative variable as labels of the points of a scatter plot. Many thanks to all for your thoughts, John On Wed, Jun 1, 2022 at 1:00 AM <gretl-users-request(a)gretlml.univpm.it&gt; wrote:
