Faded values on y-axis

[alextep2]

Hello,

I've been struggling with graphs scaling since I deployed Cacti some time ago. The y axis shows faded values for all interfaces, I've been joggling between scaling options, graph templates, data source parameters but with no luck. I'm using Cacti Version 1.2.24 on Windows.

I've attached here an example of an affected interface graph, also below you can find the graphs properties:

Hello Group,

I've attached another example. I mention that all interface graphs show the same, some of them show almost completely faded values on y-axis

To me it almost looks like an RRDtool error. You might want to choose some other font sizes. There is a file in the theme's directory that controls font sizes. rrdtheme.php I think it' what it's called.

Hello,

Appreciate your suggestion, I've changed axis font and color, also unchecked auto-scale option and now everything looks perfect, no more faded values on the y-scale. I'm not quite sure which of them was the culprit, but I won't change anything now, I'm gonna leave the current settings like this.

Thank you for the help, hope this will help other people who's struggling with the same issue.
