How to draw a graph of tree structure (using shapes and lines)?

Hello,
I tried to search this solution in the forum, and I see people asking and replying with solutions to similar situation, but I don't get what I am looking for. Also because I have never tried with graphs before.
So, my problem is, I need a function that takes a string with tree structure, as in automata or tree graph, and displays the nodes in tree form. "Tree" is not important, but important is that each object should be displayed as a node and lines connecting them. Please see the image below (with three possible options):
So, basically, the tree structure could be like X(a, X(a,b), c) where X(a,b) is a sub-tree of higher level X. The program knows the parent-child relationship, so this function only needs to display those elements in a graphical fashion.
I pass the string in the form of a 2D array showing the hierarchy (to simplify).
In the image, I am showing three possible options for showing the tree. The third option eliminates those circles and rectangles, if that simplifies.
I hope I explained clearly.
Thanks ahead!

I would start drawing from the top. The nodes will be the easy part.
Begin with the root node centered in the drawing area horizontally and against the top of the drawing area. The second row of nodes would be located vertically (as in my example) 1.5x pixels below the first one, and either distributed horizontally across the available drawing area or at a fixed distance - like 1.5x again, or someother distance you define.
The tricky part will be drawing the lines since they need run between the edges of nodes. This is where the high-school geometry might come in.
Keep us posted on what you come up with. Extra points for coming up with a solution that will automatically resize itself to fit the available drawing area! (I've already given you all the clues for how to do that too.)

How to create a tree structure using forms.

Hi,
How do i create a tree structure using oracle forms,i have a table named Functions and a specific column 'Function Name' should be displayed in the tree nodes.Can anyone help me out on how to create a tree structure and populating the nodes??
thanks in advance

How to create a tree structure using list items(tlist)

HI every one,
As we know how to create a tree structure using Hierarchy item type.
We have a requirement to create The same tree like structure using List Item(Tlist)
I would be so appreciated If you send with an example
Thanks
RangaReddy

Hi all
Any one help me please
Actually our client requirement is creation of tree structure using list item,similar to what we used in oracle Application(FNDSCSGN) form.We did the tree structure using hierarchy tree using Htree and Ftree.It working excelently.For client requirement, we want to use list item.How PJC(Pluggable Java Components) is useful for using list item(Tlist).I can't understand how it is useful.
Do you have any example please help me.
Thanks

How to draw a graph step by step ?

Hi, sirs,
Can you tell me how to draw a graph step by step by using Labview 6.0 ? On one step, I create two variables : one variable is used for X-axis, and other variable is used for Y-axis. Can you give me a simple example ?
Thanks a lot.

Try this example out.

How do i get data from a structure using join?

hi,
what is the actual use of a structure.?
my problem is :
KUAGV is an existing STRUCTURE. it has got one fields each which links to MARA, AND VBKD tables. i want to fetch all related information from KUAGV, mara, vbkd . which is the better way : using joins or views or anything else? how do i
get data from a structure using join?

structure temporarily holds any data passed to it dynamically throughout the runtime but doesnot store it permanently. so
a structure cannot be included in a join.so instead of incuding structure KUAGV's field in a join
search the transparent table in which same field are present and use it in join.
A structure if created in DDIC(Data Dictionary) is a global DATA STRUCTURE which is used to group related information, for example you would group all the details of your bank account into a structure BANK_ACCOUNT that contains fields like account_Id, account_holder_name etc.
If you create a structure in your program then it is local to your program. So you use this structure to create data holders of this DATA TYPE to hold data in your program.

Event Handling for tree structure using "CL_GUI_ALV_TREE_SIMPLE"

Hi,
I have created a tree structure using class CL_GUI_ALV_TREE_SIMPLE.
Now I wanted to insert a check and give message when the user opens the last node in my structure.
I checked the events available in the class , but there in none which gets trigered when we try to open a node.
Please guide me with this scenario.
Thanks & Regards,

As soon as you open a node in the ALV tree the report will stop at the break-point.
Now you need to check if there are still children nodes to be displayed.
If not then trigger your special coding.

I had this same problem with what's app. There is a new update for the app on the app store which is compatible with ios8. Update the app, or delete it and re-add it. I found a lot of apps weren't compliant with ios8, but after updating everything worked fine.

Could someone tell me how to control a small dc motor by using labeled and a NI 6008 daq. The motor is adjustable by using a pot that ranges between 0-V if that is of any additional benefit

Could someone tell me how to control a small dc motor by using labeled and a NI 6008 daq. The motor is adjustable by using a pot that ranges between 0-V if that is of any additional benefit.

Read the second thread you have a link to. While both of these will produce PWM signals, the first one is a couple of orders of magnitude too slow to do anything useful in control the speed of a motor, what you would see would be the motor run at the full speed, then stop for a period, then run at full speed, rather than at the "average of on and off" as the Pulse Widths will be very long relative to the motor's response. The second one has a better chance, IF all you want to do is run the motor. If there is any other calculations ... Look at both and try and get an understanding of what they are doing. For PWM speed control of a motor you really need a pretty fast pulse width, and probably some filtering to smooth out the resulting "harsh" waveform, giving you the "average" voltage resulting from the PWM.

How would I go about adding multiple rectangles using the same lines of code?

How would I go about adding multiple rectangles using the same lines of code? I would prefer to just run through a set of code every time I need a polygon. If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.

>>How would I go about adding multiple rectangles using the same lines of code?
You could create a method that creates and returns x number of Rectangle elements:
public IEnumerable<Rectangle> CreateRectangles(int numberOfRectsToCreate)
for (int i = 0; i < numberOfRectsToCreate; ++i)
Rectangle rect = new Rectangle();
rect.Fill = Brushes.Blue;
rect.Width = 100;
rect.Height = 100;
yield return rect;
..and then call this method from anywhere in your code:
IEnumerable<Rectangle> rects = CreateRectangles(5);
foreach (Rectangle rect in rects)
//add to StackPanel or do whatever with the Rectangle elements:
yourStackPanel.Children.Add(rect);
>>If I just have to create multiple polygon adding statements that's fine but I'd prefer just 1.
When adding Point objects to a Polygon you can only add one per call to the Add method but you could call the Add method inside a loop, e.g:
for(int i = 0; i < 10; ++i)
//add to StackPanel or do whatever with the Rectangle elements:
Polygon p = new Polygon();
p.Points.Add(new Point());
Please remember to close your threads by marking helpful posts as answer and then start a new thread if you have a new question. Please don't post several questions in the same thread.

I have an iphone 5s and my kids have ipods. How do i set up the ipods to use facetime and messaging without it going through my iphone?

i have an iphone 5s and my kids have ipod touches. How do i set up the ipods to use facetime and messaging without it going through my iphone or rather using my apple id? Is this possible? Does each device need its own apple ID and/or icloud email?

Try unchecking your phone number and email address (if present) under You can be reached by FaceTime (iMessage) at in Settings>Messages>Send & Receive and Settings>FaceTime on their devices. Also uncheck their email address (if present) on your phone.
Otherwise have them use separate Apple IDs for these services (tap the ID, sign out, sign back in with a different ID). You can do this and still share the same ID for other services such as iTunes.

How to draw xy graph with multiple y axis input?

Hi,
I have problem in xy graph, the xy graph only can show 1 signal from the y axis input ( As you can see in the attachment )
Is it possible to draw xy graph with 2 Y input? Or maybe there are another type of graph that possible to do this?
Note: the x axis should be from an input too ( not versus time / sample ).
All answer and advice are welcomed.
Best regards,
Alvin Chandra

Are you asking for a second Y scale on the graph?
If so, right click on the existing scale, select "Duplicate Scale". This will create a second scale. You can then (if you wish), right click on the new scale a select "Swap Sides" to put it on the other side of the graph.
Are you asking about adding a second plot?
If so then you need to bundle your arrays of X and Y points into clusters and build those into an array:
The X-axis is always from an input on the XY Graph. You just need to change the axis title. Easiest way to do this is to double click on the axis title and type the new name.
