Better representation of changes on graphs


  • The default setting for loggint is "when point value changes". I understand this is for saving database space, a good reason. However, consider this scenario: I am counting the number of clicks of a switch from a device. Let's say it is at 10 from 7:00 until 7:59, and at 8:00 it reaches 11. In the current setup (at least on my version) if I select "when point value changes" then on the graph in mango there would be a straight line from 7:00 until 8:00. This is not really accurate however, as there really should be a line from 7:00 to 7:59 and a line from 7:59 to 8:00, which which show the jump, rather than a only slightly inclined line. This can be accomplished by saving every data point, but in the interest of saving space it could probably be optimized.

    To sum it up, my wish is: if "when point value changed" is selected, then draw a line from the first data point to the point BEFORE the value changes, and then connect this point to the changed value.

    Thanks.
