Suppress Vertical Scale Values?

SpeedyZ · Post by **SpeedyZ** » Mon Sep 21, 2009 11:03 pm

Is there a way to suppress the vertical scale up the left side of a graph?

I'm logging a device that outputs a 0 for normal conditions and 1 for alarm conditions. I paint the graph green with using constant area of 1, then overlay a red a red area if a 1 is received. So the entire graph is either green for Normal, or Red for an Alarm, so I need no numbers displayed on the left. Now I currently get 0.0, 0.2, 0.4, 0.6, 0.8, and 1.0 up the left side which is a little confusing.

Thanks,

We are restricted to options available with rrdtool; that's our graphing base. If there is such an option, please tell us. We will want to support it, then.

I'd assume the OP is talking about the --y-grid none option.

Y-Axis

[-y|--y-grid grid step:label factor]

[-y|--y-grid none]

Y-axis grid lines appear at each grid step interval. Labels are placed every label factor lines. You can specify -y none to suppress the grid and labels altogether. The default for this option is to automatically select sensible values.

If you have set --y-grid to 'none' not only the labels get suppressed, also the space reserved for the labels is removed. You can still add space manually if you use the --units-length command to explicitly reserve space.

Yes, that would be the option!

I know nothing about the Cacti backend as far as how things are passed to rrdtools, but is there a file or anything that can be edited after making a graph in Cacti to allow use of this option? At least until it may be supported.

Here is some samples of my graphs. If possible it would be good to have the text displayed but not the number on the vertical scale. All inputs for these graphs are either 0 or 1. The entire block is always filled so no need for any number displayed on the left.

Hope this helps.

Thanks for a great product and support!!!

But that IS supported! simply enter "none" in the respective graph template

bah, I should've known it was that easy. just glazed over it in the graph template...

Thanks for the tip! It does suppress the scale but is there support for --units-length value? By default with blank Y label the graph is pushed all the way to the left edge where they X grid is not displayed correctly. A workaround is to put a space in for the Y label which helps the formating.

Y-Axis

[-y|--y-grid none]

Y-axis grid lines appear at each grid step interval. Labels are placed every label factor lines. You can specify -y none to suppress the grid and labels altogether. The default for this option is to automatically select sensible values.

If you have set --y-grid to 'none' not only the labels get suppressed, also the space reserved for the labels is removed. You can still add space manually if you use the --units-length command to explicitly reserve space.

[-L|--units-length value]

How many digits should rrdtool assume the y-axis labels to be? You may have to use this option to make enough space once you start fideling with the y-axis labeling.

Currently, there's no support for that option. Perhaps it will be part of 088. Not top of the list
