Hi, i tryed to draw a graph with a different sets of values. They are selected from a spinner control. For the first and second selection (no matter what value is selected) everything works well, but when i try to chose another value, my app crashed. The code is:

Sub CreateGraph(Tip As Int)
   Dim p As Panel
   p.Initialize("")
   pnl2Lines.Initialize("pnl2Lines")
   p.AddView(pnl2Lines, 0, 0, 600%x, 100%y - 200dip)

   HView1.Panel.Initialize("controls")
   HView1.Panel.AddView(p,0,0,600%x,100%y - 200dip)
   Dim LD As LineData
   LD.Initialize
   LD.Target = pnl2Lines   
   
   Charts.AddLineColor(LD, Colors.Red) 'consum
   Charts.AddLineColor(LD, Colors.Green) 'productie
   Charts.AddLineColor(LD, Colors.Magenta) 'productie
   
   For i = 0 To NrValori Step 1
   If Tip = 0 Then
      Charts.AddLineMultiplePoints(LD, Valori(i).DATA, Array As Float(Valori(i).CONSUM/1000, Valori(i).PRODUCTIE/1000, Valori(i).CARBUNI/1000), i Mod 30 = 0)
   Else If Tip = 1 Then
      Charts.AddLineMultiplePoints(LD, Valori(i).DATA, Array As Float(Valori(i).CONSUM/1000, Valori(i).PRODUCTIE/1000, Valori(i).GAZE/1000), i Mod 30 = 0)
   Else If Tip = 2 Then
      Charts.AddLineMultiplePoints(LD, Valori(i).DATA, Array As Float(Valori(i).CONSUM/1000, Valori(i).PRODUCTIE/1000, Valori(i).APE/1000), i Mod 30 = 0)
   Else If Tip = 3 Then
      Charts.AddLineMultiplePoints(LD, Valori(i).DATA, Array As Float(Valori(i).CONSUM/1000, Valori(i).PRODUCTIE/1000, Valori(i).NUCLEAR/1000), i Mod 30 = 0)
   Else If Tip = 4 Then
      Charts.AddLineMultiplePoints(LD, Valori(i).DATA, Array As Float(Valori(i).CONSUM/1000, Valori(i).PRODUCTIE/1000, Valori(i).EOLIAN/1000), i Mod 30 = 0)
   End If
   Next
   Dim G As Graph
   G.Initialize
   G.Title = "Grafic Productie / Consum"
   G.YAxis = "GW"
   G.YStart = -1
   G.YEnd = 10
   G.YInterval = 1
   G.AxisColor = Colors.Black
   Charts.DrawLineChart(G, LD, Colors.White)
End Sub

Sub Combo_ItemClick (Position As Int, Value As Object)
   CreateGraph(Position)
End Sub

What am I doing wrong? Ty!

What is the error message? You should find it in the logs.

 

[ThePuiu]

in the Logs does not apear anything, (last line is: ** Activity (main) Resume **) but my app get the message:
The application Energy (proces energy.soft) has stopped unexpectedly. Please try again. In debuger it crahs at the second selection.

Look at the unfiltered log, turn off the filter check box.

 

[ThePuiu]

i attach the project...

Try the attached code.
In your CreateGraph routine you are initializeing each time a new Panel. And you are probably getting out of memory.

Best regards.

Thank you! Works perfectly!

 

[ThePuiu]

why after passing my app into the background when I try to reactivate not there anything on display ... even the activity menu is not accessible?

You must remove the FirstTime test because the layout is not loaded nor is it initialized when the run again.
I added the saving and reading of the data type in a setup file, so the user will get the last displayed diagram.

Best regards.
