Odd looking graph

[lahrcm]

Hello, Anyone have any guesses why my graph has all that white space? It should be a continuous color on the background. (see the "wind speed/direction" graph)

I may not have the cdefs set up correctly to draw the infinity AREA colors for the wind direction, with trial and error I copied some cdefs someone else posted for the 'smokeping' type graphs.

At first I figured it was because there wasn't any data in the rrd, I don't think that's the case, see the other graph that is just graphing wind direction doesn't have the same look.... both graphs get the wind direction data from the same rrd.

Something else to further confuse me... If I zoom in on that graph the white lines don't show up.

I'm sure I just don't understand the cdef's but if anyone has ideas please let me know. Thanks!

Oh here's the rrdtool graph command so you can see the cdefs...

Ok I figured it out I think.

I removed the --slope mode option and now it looks like I expect. Does anyone know if you can disable that on a per graph basis within cacti?
