color codes ...

[gandalf]

I'm currently on the way writing some Aggregate Plugin (I may have told already ...). One of the biggest problems is the (sorry) awful color table. If it were sorted like given by http://forums.cacti.net/viewtopic.php?t=6308&highlight=colors, it would be much better.

• color assignment during template development would be much easier
  
• arithmetic increasing of color codes would be easy for my new plugin
  
• "fire effects" would be much easier

So I'm on the way to implement the second approach posted in the thread linked above. It's a very nice color table and should be "internet safe" (whatever this would be ...)

I thougth this would be easy doing. My approach was to rename the old table and import the new one. The I wanted to update all color codes used by templates and graphs by matching the id's via their hex codes

Hi Reinhard,

what's the current state of your development on the colourtables? Is there still help needed? Let me know.

Hi,
to be honest, I dropped it. While I still assume it would be a good idea, other stuff like moderation, documentation, testing upcomin cacti release and a tiny bit of coding kept me away from it.
What's your opinion on this matter?

I suggest that we do a few things, in the form of an upgrade:

1 - Backup the old color table.
2 - Create the new color table based upon the recommendations from other posters.
3 - Convert all user graph templates and static graphs to utilize the legacy colors from the new color table.
4 - Create a dropdown option in Graph Templates to that would allow all Imported Templates to be migrated to the new color tables.
5 - Modify the Drop Color to Utilize the New Sort Order

This combination of options would do it for me. If you want to help, you will write this up by making the changes in the following locations:

graph_templates.php
lib/html_form.php
install/0_8_6j_to_0_8_7.php

Hi,

I loaded the WWW safe colors from http://forums.cacti.net/viewtopic.php?t=6308&highlight=colors.

However, I can't figure out how to change the sort order from HEX to ID. I have the aggregate plugin loaded. I

changed color.php to:
$color_list = db_fetch_assoc("select * from colors order by id");

..but I can't find the other file, html_form.php, to make the change there. I'm not sure if I have different cacti version from that post or if the aggregate plugin changed this.

Can you help me adjust the color sort order from HEX to ID in cacti 0.8.6j with aggregate plugin loaded?

Looking for to the latest official Cacti release next week!

I imported the colors from the other post and re-ordered the list and it works great.

Looking forward to the latest official Cacti release next week!

[quote="sh0x"...the WWW safe colors from http://forums.cacti.net/viewtopic.php?t=6308&highlight=colors. [/quote]Yep, I know this post. IMHO, this is NOT the web save color set. My favourite resource on this topic would be http://en.wikipedia.org/wiki/Web_colors, at least for a start. To not read to many links, you will spend too much time ...

Has this progressed any further? I'd like to move this along a bit but need to know the finalized color list.
Also I 'm not so sure you need to tie yourself down to the 216 colors that are web-safe, most modern browsers handle color pretty well. The major reasons for web-safe were dithering when the desktop was set to 256 color and how browsers rendered the color called out in html. I know at one point IE had a color issue with PNG but I'm pretty sure that has been addressed. Either way you may want to consider the 4096 web-smart colors which includes the 216 color web-safe pallet.

[gandalf]

Sure. But I was under the impression, that the number of 216 colors would be enough. And scrolling through a list of 4000 elements when assigning colors perhaps does not make fun to most of us.
Still, I do not know a real good, non-manual method to map "old colors" to "new colors" to support a migration from the current color scheme to any new oine

What if you added the new scheme to the existing one and reverse sorted it leaving plenty of room between the old and the new and add colors after the old.
1-106 existing colors
1000-? new colors
107-999 user defined
sort high to low

That way you don't step on any original or user defined color so you don't break any existing templates and you get the sorted colors.


Or (I like this better) you could store the actual color in the graph_template_item (maybe other places too) instead of the color_id and use a javascript color picker like this < http://www.allscoop.com/tools/Web-Colors/web-colors.php >
you can leave the existing color table in place so as not to break any plugins that use it. A SQL command can back fill the hex values in existing templates.
Cons:
This will break existing templates unless you create a bit of logic to convert color_id to appropriate hex and and replace it during the import. Probably not a minor revision. Changing a color will then only affect the graph you change it on and not globally (this might be a Pro as it depends on how you want that to work)
