RE: FLASH: Tool Check

[Roxanne Tuton]

The scaling effect is pretty simple. Assume that you have 2 points and 1

line. You duplicate the line and set the X and Y coordinates of the line

equal to the x and y coordinates of the first points. Then set the xscale

equal to the x coordinate of the second point minus the x coordinate of the

first point. To make it stretch dynamically while you pull the points put

the actions in a looping movie clip. For example:


I have a movie named Duplicate:

The first frame looks like this....


Set Variable: "countdots" = 1

Loop While (countdots <= /:Total)

      Duplicate Movie Clip ("/dot", countdots, (countdots+1)+1000)

      If (Eval("/:x"&countdots) ne "")

            Set Property ("/"&countdots, X Position) = Eval("/:x"&countdots)

            Set Variable: "/:x"&countdots = ""

      Else

            Set Property ("/"&countdots, X Position) =

GetProperty("/"&(countdots-1),_x) + 25

      End If

      If (Eval("/:y"&countdots) ne "")

            Set Property ("/"&countdots, Y Position) = Eval("/:y"&countdots)

            Set Variable: "/:y"&countdots = ""

      Else

            Set Property ("/"&countdots, Y Position) = 10

      End If

      Set Variable: "countdots" = countdots+1

End Loop


This will make little sense as alot of it has to do with other parts of the

graph but basically, it creates a certain number of points and places them

according to certain x and y coords.


The second frame looks like this:


Set Variable: "x" = 1

Loop While (x<=/:Total-1)

      Duplicate Movie Clip ("/line", "newLine"&x, (x+1)+5000)

      Set Property ("/newLine"&x, X Position) = GetProperty("/"&x,_x)

      Set Property ("/newLine"&x, Y Position) = GetProperty("/"&x,_y)

      Set Property ("/newLine"&x, X Scale) =

GetProperty("/"&(x+1),_x)-GetProperty("/"&x,_x)

      Set Property ("/newLine"&x, Y Scale) =

GetProperty("/"&(x+1),_y)-GetProperty("/"&x,_y)

      Set Variable: "x" = x+1

End Loop


This is what attaches the line to the 2 dots.


and the final frame looks like this:


Go to and Play (2)


Self-explanatory. heh. Anyways, I built this for a couple reasons...I work

for an elearning company and it is something that I thought could be useful.

Also, the graph is set up to run by itself but if variables are passed to

it, it will plot out whatever points it is told to(text file, database,

whatever) and I plan on using it(as well as a bar graph and pie chart I am

building) to display site statistics for my site and other clients sites. I

might open source it(or something similar) on my site in about a month when

we launch our web site. It would be under tutorials or Flas or whatever we

choose to call the section. Go check out the site: http://www.flashpros.com


Not much there but you can sign the guestbook and I can email you when the

site is launched/updated.


Hope some of those tips/code help.


Scott

I love the graphing tool that you have created. In using it I found

the interface intuitive, however, when I grabbed and moved  a point

the pop up would only display the value of that point on the Y axis.

I would have liked to see the value of the point on both the X and Y

axis. I could not delete points with the delete key (on my G4). in

addition, when I scaled the X axis with the arrow slider my points,

which were at the very top of the Y axis, vanished.


I am very interested in how you accomplished the dynamic scaling and

rotation of the lines between the points. I do not know under what

conditions you created this, but I am wondering if you could share

some of your actionScript? Even friendly advice on this feat would

help me in my current project.
