[HOWTO] Sexy Traffic Graphs

Ok - Maybe not "Sexy", but better looking...

I've not used Cacti for very long, so perhaps this is a common thing people do that I've not seen, but I thought I'd let everyone else know anyhow.

Personally, I didn't like the default Traffic Graphs in Cacti. I just upgraded to version 0.8.7a, and found that I had the new opacity features, so I played around with them for quite some time, but just couldn't come up with two areas that looked decent when they overlapped. Finally, I came upon a graph on (of all things) a political website that looked great and gave me an idea...

Graph the same data twice - Once as a 100% opaque line, and again as an area with 10% opacity. This would (at least in theory) give a nice solid edge to the lightly colored area, and the areas would blend together fairly well. (I first did this on a different graph and used red and blue - Makes a nice purple!) The Green and Blue don't blend quite as nicely, but it still looks very good.

Thank you for your contribution. But you definitively should turn green into deep red to make it more sexy

Can someone who has implemented this export a graph template for it please. I seem to have goofed. (or some other change I made recently borked everything.) Trying to narrow down which :p

Oh finaly found it. I forgot to add a color to the traffic_out line added :p

Great looking graphs! Thanks for the tip.

How did you get the legend to line up so well ?

Thanks.

This is handy to know, but i'm interested if this increases processing load on the box as it has to render two lines instead of just the one line/area?

I always need to consider this with a large number of datasources.
