history plot grid lines are invisible (too light?)

[dd1]

On several computers in the detector lab, I cannot see the grid lines on history plots. At first I thought they are not plotted (we had bugs like this), but now I think they use a colour that is too light and cannot be seen on the display. The computers involved are bog standard PCs running CentOS and Ubuntu linux with bog standard LCD monitors. On my laptop at home, the grid lines are on the light side, but just about visible.

K.O.

The color is controlled at line mhistory.js:88

grid: “#F0F0F0”,

I changed it now from #F0F0F0 to #D0D0D0. Looks much darker on my LCD screen, please test it on yours. Committed to develop.
