Highlighting the decrease in red

[jurga]

Looking at the Airport Guides list I see the decrease of -26% is highlighted in red, but the decrease of -23% is not highlighted at all. Was wondering if it might be useful to highlight the decrease in red for all - if there is a decrease of course?

Same would go for the increase (green).

Just an idea. Otherwise at one glance it looks alright, nothing to worry about. Red would be a bit more shouty?

WDYT?

Right, so what I've done is set certain points. e.g. change over 25% is light red and over 50% is bright red. Same for green ones and everything else.

These values are just my own atm, but woud be good to get some input on this. @paulmaunders

The settings are as follows atm:

server response warning (light red) >= 1 server response serious (bright red) >= 2

page load warning (light red) >= 6 page load serious (bright red) >= 10

negative change warning (light red) <= -25% negative change serious (bright red) <= -50% positive change (light green) >= 25% positive change (bright green) >= 50%

How about you specify the 'color' CSS attribute as #XX0000 where XX ranges from "00" when 'safe' to "FF" at 'maximum danger'? Same goes for positive change but with #00XX00.

I was thinking about it last night, and if we assume that the only 'bad' decrease is the one that's let's say more than -15% or -20%, then gradual week-on-week decrease of 12% would still not be highlighted even though at the end of that month we'd have a total massive decrease that we should've watched anyway.

We will have a monthly summary report that should highlight such issues.

Thanks Ben. That does actually solve having to come up with values.

[jurga]

Looking forward to seeing what it looks like on the report. Thanks!

Great idea Ben - should look cool :)

Perhaps we could tweak Ben's idea slightly so that it goes through hues from yellow to orange to red, rather than from white to pink to red?

Have a look at the HSV comment on here: http://stackoverflow.com/questions/1455094/how-can-i-cycle-through-hex-color-codes-in-php

[paulmaunders]

Maybe we could combine both together - so the colour and intensity changes - although not sure how hard that is to do!

It's funny you should say this, Paul, but one of the very first functions I wrote in JavaScript for my very first website was a function called 'rainbowify' that took in a text string and returned a coloured version where the colours of the characters faded through the colours of the rainbow (red->orange->yellow->green->blue->indigo->violet) - this was before I knew any server-side scripting. I guess something like this could be used here.. depends on whether u like the output of my first suggestion. :-)

I see what you mean Paul about the hues - personally I think having two shades (green and red) and white as neutral (no change) is quite self-explanatory, as if there were more colours in between (i.e. orange) we'd need to have a legend / list of what each colour means.
