Created attachment 176891 [details] Image "Function Values - LabPlot" and Project File Description ============ For example, it is not possible to calculate the current age from the date of birth and the current date, as the date is apparently regarded as non-numerical. My use case is simple: continuous measurement of infant weight and visualisation of weight development in the WHO Child Growth Standards Charts. Steps to Reproduce =================== 1. Start LabPlot 2. Open project LB_Is05.lml 3. Select spreadsheet column “Age_days” 4. Context menu/Generate Data/ Function Values 5. Try to select “Date” for variable “x” (see image "LPIS05_01_FuncVals.jpg") Actual Result ============ Selecting "Date" is not possible. Expected Result ============== Allow calculations with Datetime values My System ========= Win10 Pro 64 bit, German LabPlot V 2.11.1, Language=English
