The "Gradient Support" option does not work correctly on aggregate graphs #5267
Comments
I looked at making it work with AREA:STACK and it did not look good. So, I reverted it. It's an open issue though. |
It's more of a technical issue as the method that the contributor used basically renders several quadrants over one another with varying colors. Each area renders from the bottom of the Y-Axis upto the path. So, the final gradient becomes all washed out, and it also does not work well with AREA's on top of AREA's due to the fact the design does not allow for Alpha Transparency. It's all technical, might be able to be fixed, but it was beyond the 1.2.x scope. Maybe we can do something in 1.3.x. |
Can you test out this rrd.php file ? replace the original lib/rrd.php with it, make a backup first. It should suport Stack and Aggregate graphs. Some graphs seem to have very light lines in them (mainly seen when using red with transparency) This is for testing purposes, please make screenshots of any issues you are seeing. It uses a light theme, so gradient is going to a lighter color. |
To be clear for going forward:

Yeah. Unfortunaltey this seems to be a rrdtool bug. If you disable "slopemode" on the graphs, it looks better, but rrdtool seems to slightly overlap the different areas, resulting in these lines. It doesn't show when no transparency is being used as it is a solid color then. I'm looking into finding a fix for that, but it's going to take a while. |
@ISekan It looks like the version breaks the "Thumbnails". Can you confirm ? |
@ISekan you do not happen to have the possibility to compile rrdtool yourself ? |
Opened a bug report with rrdtool: |

Hi, Not sure, but I don't see any gradient there, do I miss something ? |
Cacti 1.2.24
It works properly only for first item.
Is this a bug or a feature?
