ResultsViewer-saved graphs: poor image quality

asked 2015-09-10 06:16:09 -0500

When saving graphs in ResultsViewer to png image format, I have noticed that the ResultsViewer shipped with OpenStudio 1.8.0 produces much poorer quality than in previous release(s). See an example:

Here the legend is missing and the text descriptions are poorly legible. Compare this with a screenshot of the same graph:

Have I perhaps overlooked some (new) user or system settings to avoid this or is this a software glitch ?

My operating system is Windows7 32bit with OpenStudio 1.8.0 + separately installed EnergyPlus 8.3.0 (because bundled EnergyPlus crashes; cf. issue reported. ).

This was likely caused when we updated to Qwt 6.1.2 (which is still the most current version). I added this issue. However, our current focus is on reporting measures leveraging html plotting features. Have you played around with any of those yet?

Well, using ResultsViewer is very easy and convenient. I have not tried (standard) reporting measures yet, but then the question arises, how flexible and easy-to-use it is to define specific graphs or plots without having to write own measures...?
