Web Programming402
Hello everybody

I'm learning how to create pie chart using OWC.

I'm able now to create a pie.

But I can not figure out how to do the following :



- for each pie, when mousing over, I would like to display the value in a

tooltiptext

- for each pie, I would like to have in the middle, the %.



Any idea where I could find an example (using vb) to accomplish that ?



Thank you

LB

Interesting choice of words. Not "any idea how to do that?" Not "any idea

what I need to know to do that?" Instead, very specifically, you ask for

code (in VB.Net specifically) to do that.



The answer is, of course, no. And you're eventually going to find that,

amazingly, there isn't a snippet of code somewhere on the Internet that can

do everything that can be done in an application.



Programming is not the process of putting snippets together. If it was, we

could pay automotive assembly-line workers $10 an hour to put programs

together. Programming is the process of conceiving, designing, researching,

and, yes, writing code.



So, rather than giving you the fish you are asking for (for one thing it

would take me too long to write it), I'm going to point you in the right

direction, and pray that you follow it.



We're talking about a browser here, and an HTML document. While I haven't

ever used any OWCs, I would imagine that the out put is an image. If so, and

taking the HTML enviornment into consideration, you would need to

dynamically create an image map in the HTML document that contains the

image. An image map is an array of corrdinates which divide up an image into

sections. When you click one of the sections, a different URL can be

navigated to, or a JavaScript function can be called. You can also create

onmouseover events for the indivdual slices of the image. See the following

URL for details:

You will need to research how to do a tooltip as well. That can also be

Googled.

One other thing occurred to me. This OWC may be an ActiveX client-side

control. If that is the case, you're SOL. It will behave the way it is

designed to behave, and no more. In that case, your best bet would be to

create your own server-side pie-chart imaging class, that can return an

image to the page. I have seen an article or 2 on the Microsoft web site for

creating a pie chart dynamically as an image. It was a long time ago, so I

don't remember exactly where. But you should be able to search the

microsoft.com web site to find it. It has all the code you need to create a

pie chart image. Then you can go from there with my instructions for

creating an image map and tooltips.

I think you're being a little harsh here. The OP specifically asked about

OWC and for all you (or I) know, OWC might have functionality built in which

can generate a pie chart with an image map and tooltips and mouseovers, all

with one click of a button or one special command.



It doesn't do any harm to know what happens behind the scenes, but the point

of high-productivity tools like OWC is that you don't always need to know

the details.

You mean like showing a "%" when the mouse is over the imddle of the image?

I can guarantee you that this functionality is NOT present in that OWC. So,

what would YOU suggest?



Here's the deal Andy. You can think I'm being a little harsh all you want.

Personally, I tend not to have an opinion when I am not cognizant of the

facts. But that's just logic. Here are the facts, so that you can adjust

your opinion:



An OWC is a black box. It does what it does, nothing more, nothing less.

When that is exactly what you want, you're all set. When it's not, what do

you do then? Logically, you have 2 choices:



1. Change your requirements to fit the OWC.

2. Create your own app.



Obviously, LB did NOT want to change his requirements, since that is

specifically what he asked (his requirements). If he was willing to change

his requirements, he would not have asked the question. Logically, he's left

with one choice. And that was the choice I addressed.

As a non native english speaker, I won't be able to argue with you about my

"Interesting choice of words".

As a non web/asp developer, I have/had no idea about the possibilty of

event programming that could be done with an image.



However,I searched the MS web site. This is how I was able to info to create

the chart.



I will ignore your sarcasm , and search on how to create the event or get

the coordinate using images in case I do not find the correct properties in

the OWC

Thank you for pointing me out to some directions.

As a non native english reader, don't assume sarcasm where there is none!

I'm very happy to see you running with the ball I passed to you. :)

LB,

you can accomplish what you desire by hooking into the OWC event model. The

OWC is built in such a way to provide the developer with access to the low

level internals of the components thru a well-defined interface. You may

need to change the implementation of the chart so that it is not a static

image but rather a live object instance either embedded in the response

stream or in the html page. Then, you can access the tooltip events from the

chart object. I wrote an article about eventing and the OWC here:

http://support.microsoft.com/default.aspx?scid" rel="nofollow" target="_blank">support.microsoft.com/default.aspx=kb;en-us;555162. It's enough

to give you a general idea of what you need to do and how to go about

accomplishing it. But I go into a lot more detail in the Black Book.
