Configurable graph resolution setting

[timukas]

Hi,

Graph resolution setting (minute, hour, day, week) could be configurable.
Currently "minute" is default and when you have a lot of search results (several millions) then browser feels bad when drawing graphs.

Investigated a bit slowness of broswer (Firefox 29 on Windows 7 64bit), while displaying several million search results.

If resolution is default (minutes), then you have a looooot of "rect" drawings on page. This drastically slows down the performance of PC where i use graylog2 webinterface.

<div id="result-graph" class="rickshaw_graph">
<svg width="1206" height="175">
<rect x="0" y="174.63332226829877" width="4.339772727272727" height="0.36667773170123896" transform="matrix(1,0,0,1,0,0)" fill="#26ADE4"></rect>
.......
.......

When setting resulution to hours, days or months, then number of "rect" lines goes much smaller and there're no performance issues with the browser anymore.

Would be nice to have default resolutions settings globally or per-user configurable.

As a first step, when displaying graphs on a dashboard we should not draw more rects than the resolution of the graph. And if we do not draw them, there is no reason to transfer them from the server, which might also result in a performance improvement.
