Notes

Defining the default colors

The default colors for each Chartserie is entirely customizable.

• The quick way:

In the ChartView.open event use one of the following lines:

me.setDefaultColors = me.PaletteGoogle
me.setDefaultColors = me.PaletteOffice2010
me.setDefaultColors = me.PaletteWindows8

• The advanced way:

In the ChartView.open event:

Redim me.DefaultColors(-1) //Deleting all DefaultColors
 
me.DefaultColors.append &cFF0000 //red
me.DefaultColors.append &c00FF00 //green
me.DefaultColors.append &cFF0000 //purple
...
  If f is Nil or f.Exists = False then
    MsgBox("Ressource files are missing")
    Return
  End If
test=250

Changing display options when loading Data

When using one of the following functions:

• LoadFromCSV
• LoadFromDB
• LoadFromListbox

The ChartView automatically refreshes the display.
If you need to edit the display before refreshing, you can use the Freeze property to prevent refreshing:

me.Freeze = True //This freezes the display until you unfreeze it
me.LoadFromListbox(Listbox1)
 
//Edit the ChartSerie colors
For i = 0 to Ubound(me.Series)
 
  If i = 0 then
    me.Series(i).FillColor = &cFF0000
  Elseif i = 1 then
    me.Series(i).FillColor = &c00FF00
  Elseif i = 2 then
    me.Series(i).FillColor = &c0000FF
 
//And so on for all series
  End If
Next i
 
//Edit the Y Axis
me.Axes(1).MinimumScale = 10
 
me.Freeze = False //Unfreeze the display
 
If me.Animate then
  me.StartAnimation()
else
  me.Redisplay()
End If
