Question #199322 on Graphite changed: https://answers.launchpad.net/graphite/+question/199322
Michael Leinartas proposed the following answer: During rendering, Graphite calculates the space between each point-draw to properly line up the values to the graph width. Once the space between the points gets below the line width (default 1.2 pixels) they start to 'smoosh' together, so at this point Graphite reduces the number of drawn points by consolidating them with an average() function. You can change this to a sum() function instead by wrapping the series in the cumulative() function (http://readthedocs.org/docs/graphite/en/0.9.10/functions.html#graphite.render.functions.cumulative) but note that it may not be what you expect as you'll be displaying the sum of the points which went into that drawn point (which may not line up with an actual value in the data). If you're already using summarize, you can get the real values displayed by summarizing to a longer interval (thus reducing the number of points displayed). You can also fiddle with the threshold used before point consolidation occurs, minXStep: http://readthedocs.org/docs/graphite/en/0.9.10/render_api.html#minxstep and tweak the line width if the lines get too messy http://readthedocs.org/docs/graphite/en/0.9.10/render_api.html#linewidth -- You received this question notification because you are a member of graphite-dev, which is an answer contact for Graphite. _______________________________________________ Mailing list: https://launchpad.net/~graphite-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~graphite-dev More help : https://help.launchpad.net/ListHelp
