After much discussion (and request), we have added the ability to show lines that connect your glucose log entries on Log for Life's main glucose graph.
One of our biggest hang ups with adding lines to the graph has been that it can portray an incorrect representation of the data. A casual observation of two glucose data points connected via a straight line could lead one to infer that glucose is moving linearly between two readings or that the line is an estimation of glucose levels between the two points. Neither of these situations necessarily reflects the actual glucose levels for an individual, and we wanted to be careful to avoid this misrepresentation.
Graph readability is something that we care a lot about, and we decided that having the lines is a huge win for readability, particularly for graphs with a lot of glucose data points. However, to encourage correct representation of the data, we decided not to connect the points completely but to leave a space between the lines and the dots. We also made the lines slightly transparent in order to emphasize the entry points and not the lines.
To show or hide the lines, we've added two buttons to the bottom left of the graph:
Whichever setting you choose will be saved so that you don't have to change it every time you view your graph.
Enjoy!
