[ANSWERED] Graph, RRDTool, Title in 2 lines

[Sirup]

Is there a possibility to "wrap" the title of a graph in to lines?

Example in the screenshot

[Linegod]

No. RRDTool does not support this.

[Sirup]

Okay thanks a lot.

[gandalf]

No. RRDTool does not support this.

J.P., yes, this is (has been?) the standard answer.

Now that I read it, it comes to my mind that rrdtool 1.4.x supports pango markup. This way, it may be possible to tweak a <br/> into the title. I did not test that. But if plain rrdtool 1.4.x works well, then Cacti 088 will support it!

I will see what I can do with v1.4 if I get a chance...

[Linegod]

Just a test below. Not 'simple'.

I will take a look at 0.8.8 and see what I can do....

[Sirup]

Perfect!

How did you do this? So this will probably work with cacti 0.88 and rrdtool 1.4.x but not in the combo 0.88/1.4.x?

[Linegod]

The '--pango-markup' option needs to be passed to the 'rrdtool graph' command. Unicode Entity in hexadecimal notation needs to be passed in the title for newline in the title.

It works with rrdtool 1.3.9, but it will have to wait for 0.8.8, as some logic around when to apply it will have to be included.

[Sirup]

Thanks again - for the technical details

What are the steps that I need in order to put 2 lines in the Title of the graphs.

[juangose]

My version is Cacti 8.8b

MY RRD is 1.4.x

[*] To use the pango-markup feature mentioned by Linegod, you can use it this way:

Code: Select all

--pango-markup --title='<span>Line1&#xa;Line2&#xa;Line3</span>'

The output will look like this (which is probably just fine if you use two lines, but not that pretty if you use more than two lines):





[*] As a work-around, you can use a newline-patch I wrote for rrdtool-1.6.0. You can use it this way (with "?" as our separation character):

Code: Select all

--title='Line1?Line2?Line3'

The output will look like this:
