Graphs
« on: September 06, 2007, 04:40:27 PM »
Hi all !

We have a project to accomplish that contains lots of graphs in it.
I have some questions:

In Illustrator, it is possible to create pie-graphs (and make them visually attractive as I found out: http://www.modernlifeisrubbish.co.uk/article/howto-make-pretty-pie-charts).

1. How do I automatically set the percentages outside of the pie? Example: 50/50 splits the pie in half, I also would like to see those values set as text '50%'; '50%', surrounding the pie. Possible?

2. Is there a plugin or application that has more 'advanced' ways of creating graphs (suitable for printed media)?

Excuse me if I am ignorant in this, it's only that I have not created graphs for a long period, any suggestion would be gladly appreciated.

TIA, Erwin

I'm not totally understanding what you mean by #1. If you enter the values in the fields it splits it up automatically. You have to add the labels manually.

I don't know of any plug-ins, but that doesn't mean they don't exist.

Hi Erwin,

Actually, you can set your labels in the top row of your graph data so in your case your data would look like:
50%|50%
-----+-----
50.00|50.00
Note that you will have to calculate your label percentages yourself.
Set your labels to appear inside the wedges.

Once your graphs are done, you can ONLY select the labels and scale them proportionally (Making sure you put the "origin" of the scale tool on the center of your pie chart). This will eventually set the labels outiside of your wedges and exactly in the center of each outside arc. You only need to set the type size of your labels and you are set.

I do not know of  a way to do this automatically nor do I know of a Plug-in that would do the trick. There might be a way to accomplish this with Applescript but I haven't checked yet.

Also: You might want to try the 3D Extrude and Bevel filter, this really makes the graphs pop out.

Have you looked at making the graph object dynamic you may be able to script importing it's data that way. I haven't been able to work this out though.

I had a look at the dynanic aspect again (had to refresh my memory it's been some time since I last did this). Create a template file containing 1 pie chart style graph as per michel's suggestion (no need for any data yet) in the in the variables pallet with the graph object selected make object dynamic. From there you can now import XML containing your multiple graph information. Once this is done you can colour the live graph with basic fills strokes etc when you accept this the information will then be applied to all the graphs contained in the datsets. (it is best to start with the pie chart that contains the most sections) the nice thing about using variables is that any changes made to the first dataset are applied throughout so updating colours fonts etc is made very easy and all your info is contained in the one template file. I would imagine if you have lots of graphs of similar styles then you could save quite a bit of time with this method. The XML itself when opened is pretty easy to interprit and I would not envisage it being too difficult to create a script to write this information from a database program such as excel or FMP. Here is a basic sample of graph XML code you can try importing.

Just save from text edit as plain text with .xml extension.
It is also possible to script the import and export of XML from illustrator and to output each dataset to file. Where you can crack open the graph and use none basic fills like patterns and raster effect etc.

Larsen: thanks for your valuable information. My scripting-experience is however zero-to-none, so I have to further investigate this before I can use this to automate it to our advantage.

The project indeed contains mainly similar graphs, only containing different data (values) and oncoming periodically, so it is worthwile to automate this.

Other than the things I can find on the internet, could you point me some references to books in which I can find more about this?

Thanks again !

I tried Larsen's dynamic data trick but couldn't make it work. Somehow the resulting text file is not compatible with what Illustrator expects. I also did the reverse and exported a set of variables from Illustrator. Sure enough, comparing the two text files, they were different (something about a line feed character at the beginning of each paragraph). I also never found the "text only" in textEdit.

I have just thought that I never checked that the posted code would work after posting. I have done this this morning and all is fine at this end. Draw one plain pie chart and import the saved text file. What I explained poorly is I have text edit use plain text and not rich text and save to Unicode (UTF-8) as that is what is specified in the .xml head then keep .xml and don't Append when saving. You should then get a list available from the drop down menu of datasets in illustrator. I did also make some ground on trying to script this feature too. I will play some more when I get the chance.

Michel, for what its worth here is where I got to playing with this. Its partially hard coded while I play but is working fine for me no issues with the xml being invalid.
