Created attachment 176272 [details] screencast This is an enhancement report, however, I think it is a major one. To deal with data one must all the time have a closer look (outliers, poles, error bars etc.. Therefore it is crucial to - hover with the mouse over a data point and see the coordinates of the point - zoom in to a region of interest (and zoom back out) At least for me the feature has become so normal that this is a major struggle for me with LabPlot. As example attached is one of my favorite implementations (PlotlyJS: https://plotly.com/javascript/error-bars/). I also noticed that many plot libraries offer this feature meanwhile. (for example I use FreePascal because of its nice Lazarus IDE for my custom laboratory software as it allows this feature too) Maybe the library LabPlot uses can offer this feature too.
