Gradient Graphs for Cacti

[kinghaye]

Greetings everyone am new to this Cacti software so forgive me for asking dumb question but when i log in through SSH and browse to nano /path/to/cacti/lib/rrd.php the file is blank. should i just add the code or the graph template ?

[kinghaye]

How can download and install the rrd.php file in the correct directory since mine is blank.

[kinghaye]

found the location of the file however when i apply the code all my graphs are gone. any idea what might cause that?
/usr/share/cacti/site/lib

What Cacti version are you using ?

Hello
How to make that color grading was only in the area, and did not fill line?

Someone should do a pull request against the Github release for this.

I just backed up the original rrd.php and dropped this in place. All my graphs look sexy now! Nice add on

Dragging this back to the top to see if this might be updated to work with the new 1.x version? Very cool...

Thank you!! Love it!! Did forget about the fact that transparency goes away - but I'll adjust my graphs to make those work. Thank you so much!!

You can change this line:

Code: Select all

// We don't use alpha blending for the area right now
$alpha = 'ff';

to this, to get transparency working ( it may look ugly though ... ? there was a reason why i disabled this ... )

Code: Select all

// We don't use alpha blending for the area right now
//$alpha = 'ff';

Was also just checking out an odd behavior with the autoscaling of using the Area graph item type. With the gradient applied, the "auto scale options" don't seem to be working.

Just curious if it's a bug or just the nature of getting the gradients to work...

Thanks!

Ha! Yeah - now I can see what transparency isn't a real good option here... At least with the type of graph I'm using... Even with everything at 10% it's still very hard to see...

Thanks for the details though - still may be able to design the graph in a way to make it work!!
