You want to write two views. One that displays the graph and the form and 
another that generates the graph. There are several options here:

1. You have a custom content object that stores the configuration from the 
HTML. During image generation, you simply use the data.

2. The HTML data is simply encoded in the image source URL and is used by the 
image generating view:

[Zope3-Users] Complex views implementes in Python

[Nicolas Legault]

I'd like to develop a page that is most like the PDF example in Phillip's
worldcookery but with some modification parameter

Here is what I want:

Construct a page that will have a graphic image (JPEG for example) with a
form under the graph that can control some parameter to generate the graph,
like a dates for intervals of the X axis, maximum and minimum for Y axis.

What I need from the user's point of view:

1- the user will load the page and see a graph with default parameter
(today's date...) and a form under the graph with empty fields.
2- the user can enter some data in these fields and leave others blank
(default will be used for field leaved blank)
3- the user click the submit button and the new graph appear with, again,
the form under the image.


After examining the worldcookery PDF example, I see how to implement the
generation of the image, what I don't understant is how to include this in
an HTML with a form and pass these value to the graph function.

A long time ago I've implemented a web page like this in 100% pure code and
what I've done was:

- Examine the GET/POST to get passed parameter.
- used default value for blank parameter.
- create the graph and write it on a temporary name on HD.
- construct the HTML returned code with a  pointing to the
graph
- return the code to the remote browser.


Thanks in advance.
