TEXTALIGN

[Wirthmueller]

I am using cacti version 1.2.8 running on a linux PC (ubuntu).

What I wanted to do is nicely arrange the values in the legend right-aligned in columns for MIN, LAST, AVERAGE, and MAX values.

I have used /t to arrange it more or less in columns however it is not really working since the numbers do not always align.

I noticed that in the graph template in the graph item types there is a "TEXTALIGN" in the pulldown menus providing "none", "left", "right", "justified" and "center". So I tried to use these but whatever I choose it does not change the placement of the figures of the legend at all.

This is my RRDTOOL command:

Code: Select all

/bin/rrdtool graph - \
--imgformat=PNG \
--start='-86400' \
--end='-300' \
--pango-markup  \
--title='Legend' \
--vertical-label='Degrees Celsius (°C)' \
--slope-mode \
--base=1000 \
--height=200 \
--width=700 \
--alt-autoscale \

Any help to this?

I think TEXTALIGN is just for wrapping. What we need is a new form of tab and not so much an align. There is presently a tab width, but there is to my knowledge, no center align tab, or right align tab. You should check me on that. This makes creating a good alignment difficult. You can set the widths of the various GPRINT data but that does not cover all alignment situations.
