 dinamic setting of the labels (reading from a txt file) |

hi,
taking your example in the documentation....
Public Sub createChart(viewer As Object, chartIndex As Integer)
Dim cd As New ChartDirector.API
' The data for the bar chart
Dim data()
data = Array(85, 156, 179.5, 211, 123)
' The labels for the bar chart
Dim labels()
labels = Array("Mon", "Tue", "Wed", "Thu", "Fri")
.
.
.
how could I set the labels reading a line from a txt file (eg. mylabels.txt) where the content of the first line is:
Lunes, Martes,Miercoles,Jueves, Viernes
in other words...how to create the array reading the values from an external files and not "hardcoded" like in the example.
thank you very much in advance for your help.

Hi IMZDE,
To use data from a text file, you just need to use the functions in your programming language to read in the text file, and store the data into the arrays.
The sample code mentioned in your last message is for classical VB6, so I assume you are using VB6 as the programming language. In VB6, the Open statement opens a file, the "Line Input" statement reads in a line, and the "Split" function converts the line into an array. It is like:
'Open File
Dim fileNo As Integer
fileNo = FreeFile
Open "c:text.txt" For Input As fileNo
'Read first line and split into array to become the labels array
Dim line As String
Line Input #fileNo, line
Dim labels
labels = Split(line, ",")
'Read second line and split into array to become the data array
Line Input #fileNo, line
Dim data
data = Split(line, ",")
Close #fileNo
Hope this can help.
