The GRAPH command allows users to quickly build svg graphs. The command has many settings that can be set, but one not included is the ability to format the y axis. In order to modify the y axis values, the svg can be manipulated using the SVG component, and/or 4D's DOM commands. Below is an utility method that adds a pattern the the front of the y axis.

// Method: GRAPH_PREPEND_TO_Y_AXIS // $1 - Source grahp // $2 - pattern to prepend // $0 - Modified graph C_PICTURE($1;$input_picture) C_TEXT($2;$pattern) C_PICTURE($0) If (Count parameters>1)    $input_picture:=$1    $pattern:=$2    $svg_ref:=SVG_Open_picture ($input_picture)        If (SVG_Is_reference_valid ($svg_ref))       $xml_ref:=DOM Find XML element by ID($svg_ref;"ID_y_value")       If (SVG_Is_reference_valid ($xml_ref))          DOM GET XML CHILD NODES($xml_ref;$nodes;$nodeRefs)                    For ($i;1;Size of array($nodes))             $y_ref:=$nodeRefs{$i}             If (SVG_Is_reference_valid ($y_ref))                DOM GET XML ELEMENT VALUE($y_ref;$y_val)                DOM SET XML ELEMENT VALUE($y_ref;$pattern+$y_val)             End if          End for          SVG EXPORT TO PICTURE($svg_ref;$0;Copy XML data source)       End if    End if End if

Example:

The code generates the graph:

C_PICTURE(vGraph) //Variable of graph ARRAY TEXT(X;2) //Create an array for the x-axis X{1}:="1995" //X Label #1 X{2}:="1996" //X Label #2 ARRAY REAL(A;2) //Create an array for the y-axis A{1}:=30 //Insert some data A{2}:=40 ARRAY REAL(B;2) //Create an array for the y-axis B{1}:=50 //Insert some data B{2}:=80 vType:=1 //Initialize graph type GRAPH(vGraph;vType;X;A;B) //Draw the graph GRAPH SETTINGS(vGraph;0;0;0;0;False;False;True;"France";"USA") //Set the legends for the graph

To add a '$; sign to the front of the y axis labels, run GRAPH_PREPEND_TO_Y_AXIS:

vGraph:=GRAPH_PREPEND_TO_Y_AXIS(vGraph;'$')

The resulting graph looks like the following:
