How do I put the legend only once in a multi-graph? There doesn't appear to be an option for that in the Advanced Graph Editor.

As you can see in below example, the legend repeats for each multi-graph. I want it only once.

If its only HTML, then add some before the graphs.

I'm not talking about the heading, Waz, but about the legend.

How the legend gets rendered depends on how many lines are in my graph and what colours they get assigned by the template. Although I can control that by setting the series colours of the first n series by hand, of course.

I guess I'll go check the Perspective documentation for that...

Yet... HTML is the way to go here, it turns out. Trying to do that in the multi-graph would be troublesome, it seems.

I had assumed that a multi-graph would be a single image, but it's not. It is an image per graph.
I could add the legend to only one of the images in the multi-graph. I think that is possible using a DEFINE that evaluates to 'true' or 'false'.
However, the legend takes space off the graph image, and since all the images in the multi-graph get the same size, doing so would yield a rather "distorted"-looking result. In my case of 4 graphs I would get 3 graphs that would span almost the full width of the image, but one about half that width because it has the legend next to it...

Thankfully, the HTML route was safe to take here, as the legend items are fixed for these graphs.

I ended up using this HTML:

-IF &LINES EQ 0 THEN GOTO LBL_EMPTY;
-HTMLFORM BEGIN
<style type="text/css">
#legend {
	position: absolute;
	top: 60px;
	left: 520px;
	font-size: 8pt;
	font-weight: bold;
	list-style: none;
}
#legend li {
	margin: 2px 0;
	padding: 0;
	font-size: 8pt;
	font-weight: bold;
}
#legend img {
	width: 6px;
	height: 6px;
	vertical-align: middle;
	border: 1px solid black;
	margin: 0 4px 0 0;
	padding: 0;
}
</style>
<ul id="legend">
[*]<img style="background-color: rgb(192, 0, 0)" src="/ibi_html/javaassist/spacer.gif"/> Item 1
[*]<img style="background-color: rgb(0, 0, 192)" src="/ibi_html/javaassist/spacer.gif"/> Item 2
[*]<img style="background-color: rgb(0, 0, 192)" src="/ibi_html/javaassist/spacer.gif"/> Item 3
</ul>
-HTMLFORM END
-LBL_EMPTY

I tried doing this with DIV's instead of transparent images, but IE7 just refused to make the DIV's less high than a full line-width. It did work fine in Firefox and (presumably) other standards compliant browsers. I think the IE7 problem was due to it rendering the page in compatibility mode, probably due to the HTML that WF generates.

You know, I realy need to read these more carefully.

Sorry about that.

I think I need a lie down.
