ThingSpeak data tips Matlab Visualization Plot

I want to create a ThingSpeak Matlab Visualization Plot with data tips (similar to the defaut ThingSpeak plot visualization). When I enable this with after tge plot with: dcm = datacursormode; dcm.enable = "on"; I get data tips that say how long ago the plot was updated ("seconds ago"). So I tried to define an update function (from an example). But that did not help. Seeing the Matlab code that generates the default ThingSpeak plot would likely answer my question...but I could not find it. dcm.UpdateFcn = @displayCoordinates; function txt = displayCoordinates(~, info) txt = {sprintf('X: %.5f', info.Position(1)), sprintf('Y: %.5f', info.Position(2))}; end
