UPDATED 14/10/09

EDIT - also see my new GDI+ version of this UDF

Hi!

I've created a lot of programs/calculators that use graphs, and have been meaning to create a simple UDF to allow quick creation of graphs and their x / y axes.

Here is what I have done so far, I'll add other features as I come up with them.... hopefully it should end up with things like bar-charts, scatter plots etc in the future.

FUNCTIONS:

_Graph_Create ...............creates the graph area

_Graph_Clear..................removes any plotted items

_Graph_Delete.................deletes graph and labels

_Graph_SetRange_X.........sets the x axis

_Graph_SetRange_Y.........sets the Y axis

_Graph_Plot_Start............moves the starting plot position (equivalent to $GUI_GR_MOVE)

_Graph_Plot_Line.............draws a line

NEW FUNCTIONS (14/10/09):

_Graph_Plot_Point.............plots small square around x,y

_Graph_Plot_Dot...................plots a single pixel at x,y

_Graph_Set_PenSize................sets next pen size

_Graph_Set_Color..................sets the colour/background colour of next drawing

_Graph_Plot_Bar_X.................plots a bar chart bar along the x axis

_Graph_Plot_Bar_Y.................plots a bar chart bar along the y axis

_Graph_SetGrid_X..................sets the x axis grid

_Graph_SetGrid_Y..................sets the y axis grid

The UDF:

Notes:

Thanks to joseLB for looking at adding grid lines to the graph area. I hope you don't mind, but I changed the approach quite a bit. I wanted to keep it in line with the 'standardised' approach of the other functions.

Actually, I wish I'd approached this UDF in a completely different way now, but it's used throughout my statistical software and major changes would render those programs useless! argh!

Feel free to comment / criticise!

Gosh, that was quick!! Thank you for testing!

I've just noticed something 'unusual' about the example screen-shot (now removed) I gave above...the x axis labels are 2, 4, 6, 8, 11, 13, 15...

Thought I'd explain why this happens before ppl comment:...

The label names are calculated from the specified upper and lower limits in _Graph_SetRange_X, and the floats are rounded by the function. So make sure you specify a rounding value if you want to avoid this anomaly!!!

I just looked for an UDF like this to display simple measured values (FPS and CPU time).

Your sample worked like a charme :P

Thanx!

Hi!

I've created a lot of programs/calculators that use graphs, and have been meaning to create a simple UDF to allow quick creation of graphs and their x / y axes.

Here is what I have done so far, I'll add other features as I come up with them.... hopefully it should end up with things like bar-charts, scatter plots etc in the future.

Looking forward to that!

Thanks for sharing.


Don't bother, It's inside your monitor!------GUISetOnEvent should behave more like HotKeySet()

I would suggest adding grid lines.

Cant test it on this school computer but I will look into it later.

Hi Andy, great job! Simple to use and straigth to the point!

I did an AU3 to graph about 750 points in almost no time with your UDF and your example.

I was tooking lots of time trying to do it with GDI+ functions, but labeling X, Y is a nightmare...

I just would like to suggest one more function for labeling + grid

_Graph_Labels(title, Xlabel,Ylabel,Xgrid,Ygrid, grid intensity)
where:
title= string with title that appears centered at top of graph
Xlabel= string with text that appears centered at bottom of graph
Ylabel= string with text that appears over the x axis
Xgrid= 0 -> no grid, other numbers = multiple/submultiple of Xtics, where:
           1=    one vertical line over each Xtick, 
           0.5=  one vertical line over each half Xtick,
           2=    one vertical line over each 2 Xtick,  and so on... (3, 4,...)
Ygrid= 0 -> no grid, other numbers = multiple/submultiple of Ytics, where:
           1=    one vertical line over each Ytick, 
           0.5=  one vertical line over each half Ytick,
           2=    one vertical line over each 2 Ytick,  and so on... (3, 4,...)
Grid Intensity= 0 to 255 for X/Y grid (gray scale )

Thanks

Jose

Hi Andy

I did a Grid Function for your UDF! I hope you like it.

All others interested in grids!

Add this code to Andy's UDF so you can do Grids on your graphics

; #FUNCTION# =============================================================================
; Name...........: _Graph_Grid
; Description ...: makes X and/or Y grid. 
; Syntax.........: _Graph_Grid($graph, $Xlines, $Ylines, $color=0xf0f0f0)
; Parameters ....: $Grap - the array returned from _Graph_Create
;     $Xlines - # of grid lines per _Graph_SetRange_X  Xticks -> 1= one line per tick,   2= 1 line at each 2 ticks...,   
;                0.5= 2 lines per tic.  Default=1,  and 0=no X grid
;     $Ylines - # of grid lines per _Graph_SetRange_Y  Yticks -> 1= one line per tick,   2= 1 line at each 2 ticks...,
;                 0.5= 2 lines per tic.  Default=1,   and 0=no Y grid
;     $color - [optional] RGB value, defining color of grid. Default is a light gray, 0xf0f0f0
; =======================================================================================
Func _Graph_Grid($graph, $Xticks=1, $Yticks=1, $color=0xf0f0f0)
GUICtrlSetGraphic($graph[1], $GUI_GR_COLOR, $color)
  
  If $Xticks > 0 Then
  For $k = $graph[6]+$Xticks to $graph[7] Step $Xticks
   _Graph_Plot_Start($graph,$k,$graph[8]) ;grade
   _Graph_Plot_Line($graph,$k,$graph[9])
  Next
EndIf
If $Yticks > 0 Then
  For $k = $graph[8]+$Yticks to $graph[9] Step $Yticks
   _Graph_Plot_Start($graph,$graph[6],$k) ;grade
   _Graph_Plot_Line($graph,$graph[7],$k)
  Next
EndIf
GUICtrlSetGraphic($graph[1], $GUI_GR_COLOR,0)
EndFunc

Hi,

Keep improving this UDF, don't give up.

Graphics are a must for data visualization.

This UDF rock's. :D

Thanks you very much,

Hi,

thanks for the grid function. :D

To display graphics within an AutoIt GUI you may probably also have a look to imbed one of the (flash) graphic engines here. :D

Ciao,

thanks for all incentives.

So, here are 2 new small functions and the complete Graph.udf (nothing changed for old users, just added these 2 functions:

_Graph_LineColor --> changes color for all future drawed lines up to a new _Graph_LineColor.

_Graph_Mark --> start to put "+" marks at the end of each drawed line.

Hi andybiochem,

When I saw this Funcs ,some months ago I thought, that it could be very useful for me to have some similar Functions, which would make my maths homework :)

So I started to edit your Funcs and I also added some. But time changes, so also our topic in school changed and this work seemed useless to me.

Because I think, that they may could help you to make new Funcs or something like this, I post them here. Maybe you find some parts which are useful for you.

And sry this were my first udf's in AutoIT and I'm still a noob in coding so sorry if there are many mistakes or if there's something very complicated in the code

here's the code

#include-Once
#include <GUIConstants.au3>

 Functions:
 _Graphcreate ; Done
 _Graphclear ; Done, not tested
 _Graphdrawcosy ; Done
 _Graphdrawstraight 
 _Graphdrawgrid ; Done
 _Graphdrawpoint ; Done
 _Graphdrawline ; 
 _Graphdrawcircle ;  
 _Graphdrawhalfline ; Done
 _Graph_Reference_pixel ;;;; Function completely made by andybiochem

To do:
 _Graphdrawhalfline ; Make lines bigger => $GUI_GR_PENSIZE !
 _Graphdrawstraight ;
 _Graphdrawline ; 
 _Graphaddinfos ; Add infos about the geometrical constructions like radius etc. to the graphic
 _Graphgetpoint ; ??????
 Remove _Graph_Reference_Pixel (?)
 Shorten _Graphdrawhalfline
 Draw nothing beside the Graphic
 Make it work for more than one _Graphcreate
 _Graphdrawpoint in relationship to the graphic
 
 
 Done since 9.9.09
 _Graphdrawhalfline
 _Graphdrawhalfline define graphname function ($xhalflinename,$yhalflinename) and make name larger 
 _Graphdrawpoint make larger X
 _Graphdrawhalfline ; halbgerade ; geht im moment nur mit positiven m-werten (Steigung)
 _Graphdrawhalfline Graphenname bei manchen Graphen noch falsch
 _Graphdrawpoint ; label mit koordinaten und punktnamen
 -Remove ToolTips
 - Fixed some problems with _Graphdrawpoint
 _Graphdrawcircle fertig
 
 
 Date of finishing the udf  :              soooon :D

You can use it for things like this

Thanks for the udf.

I'm trying to add a graph to my GUI and I don't know the difference between this UDF and GDI+ one.

The case is that I want to fill something like:

Posted Image

with the values of a variable that I change manually with something like guictrlsetdata($variable,10)

Can I draw a line between every point with this version or I'm going to need the GDI+ one?

It would be great to see the evolution of a measuring program.

And when I've more than 10 or 20 result can the first ones be moved outside the graph?

Posted Image

Because there is going to be a moment where the points will not fit inside the graph ;)

(I've a poor english level, maybe _Graph_Plot_Start is what I'm asking for?)

Thanks for your contribution.

adolfito121, take a look at this post of andybiochem.

Thanks ;)

EDIT:

I don't know what I'm doing wrong

I've taked the example from andybiochem and tried to adapt to my script like that:

Global $aData = GUICTRLREAD($input7)
Global $i = 1
Global $gGraph = _Graph_Create(30, $altogui4 - 320, $anchogui4 - 250, 280)
_Graph_Set_Color($gGraph, 0x000000)
_Graph_SetRange_X($gGraph, 1, 20, 20)
_Graph_SetRange_Y($gGraph, $valorinput2, $valorinput1, 10);The minimun and max values are going to be variables from an user input at the beggining of the program

Func _Redraw()
    GUISetState(@SW_LOCK)
    _Graph_Clear($gGraph)
    _Graph_SetGrid_X($gGraph, 5, 0x468c2f)
    _Graph_SetGrid_Y($gGraph, 10, 0x468c2f)
    _Graph_Set_Color($gGraph, 0x000000)
    _Graph_Plot_Start($gGraph, 1, $gGraph[1])
    _Graph_Plot_Line($gGraph, $aData, $i)
    _Graph_Plot_Point($gGraph, $aData, $i)
    _Graph_Refresh($gGraph)
    $i = $i + 1
    GUISetState(@SW_UNLOCK)
EndFunc   ;==>_Redraw

I've tried to adapt taking out the random part of this example:

#include <GUIConstantsEx.au3>

GUICreate("", 586, 314, -1, -1, -1, 0x2000000)

Global $aData[101]
Global $gGraph = _Graph_Create(50, 18, 513, 254)
_Graph_SetRange_X($gGraph, 1, 100, 0)
_Graph_SetRange_Y($gGraph, 0, 100, 10)
_Redraw()

GUISetState()
Do
    Sleep(50)
    _Randomise()
    _Redraw()
Until GUIGetMsg() = -3

Func _Randomise()
    For $i = 1 To 99
        $aData[$i] = $aData[$i + 1]
    Next
    $aData[100] = Random(0, 100)
EndFunc   ;==>_Randomise

Func _Redraw()
    GUISetState(@SW_LOCK)
    _Graph_Clear($gGraph)
    _Graph_SetGrid_X($gGraph, 5, 0x468c2f)
    _Graph_SetGrid_Y($gGraph, 10, 0x468c2f)
    _Graph_Set_Color($gGraph, 0xF9F32B)
    _Graph_Plot_Start($gGraph, 1, $gGraph[1])
    For $i = 1 To 100
        _Graph_Plot_Line($gGraph, $i, $aData[$i])
        _Graph_Plot_Point($gGraph, $i, $aData[$i])
    Next
    _Graph_Refresh($gGraph)
    GUISetState(@SW_UNLOCK)
EndFunc   ;==>_Redraw

But trying to make the value $aData the value of a variable:

$coord1 = PixelSearch($size[0], $size[1] + $mitad, $size[0] + $size[2], $size[1] + $mitad, $color, $algoritmo * 3);~a pixelsearch with its coordenates

            If Not @error Then ;
                $medida = ($size[2] - $coord1[0]) / 10;~I just need the distance between the starting coordenates of the searching area of pixelsearch and the point where it found the pixel searched
                
                StringFormat("%#.2f", $medida)
                GUICtrlSetData($input7, $medida);~I tell the script to write on an only read inputbox the value given for that pixel search (a distance between two points, basically)
;~Finally I try to send the data to the graph
                _Redraw()

When I'm doing the pixelsearch the graph flashes and it turns transparent and it doen't shows any point or neither any line.

Do I'm very far of my porpouse?

Thanks again

If you want to draw a value from the input, modify like this

Func _Randomise()


    For $i = 1 To 99
        $aData[$i] = $aData[$i + 1]
    Next
    $aData[100] = GuiCtrlRead($input7)
EndFunc   ;==>_Randomise

mersi taietel.

$i value is "how many points are going to be drawed before starting moving the graphs to the side"?

I've two gui (one transparent to limit the pixelsearch area and the main one where grapmust be drawed.)

At the starting of the script the graphs is showed on the maingui, but when is going to draw the firs value the graph remains on it's place and the little gui shows a line.

This is how it looks at the beggining

and this is what it does when it has to draw the first redraw the graph

Posted Image

I'm sure that it has to be my fault (my wife tells me everytime, on everything, so that time is not going to be different).

I call the _redraw and the _randomize functions with a button:

$coord1 = PixelSearch($size[0], $size[1] + $mitad, $size[0] + $size[2], $size[1] + $mitad, $color, $algoritmo * 3);~a pixelsearch with its coordenates
If Not @error Then ;                 
$medida = ($size[2] - $coord1[0]) / 10;~I just need the distance between the starting coordenates of the searching area of pixelsearch and the point where it found the pixel searched                                 
StringFormat("%#.2f", $medida)                 
GUICtrlSetData($input7, $medida);~I tell the script to write on an only read inputbox the value given for that pixel search (a distance between two points, basically) ;~Finally I try to send the data to the graph                 
_Randomise()
_Redraw()

The transparent gui is created with this parameter:

$Guipeque = GUICreate("minigui", $posicionxguipeque1, $posicionyguipeque1, $altoguipeque1, $anchoguipeque1, $WS_POPUPWINDOW, $WS_EX_LAYERED + $GUI_WS_EX_PARENTDRAG, WinGetHandle(AutoItWinGetTitle()))
WinSetOnTop($Guipeque, "minigui", 1);~to make the gui over the main gui, because is going to be a searching area limitator
GUISetBkColor(0xABCDEF)
_WinAPI_SetLayeredWindowAttributes($Guipeque, 0xABCDEF, 255)

Any ideas of what I'm doing wrong?

Thanks again
