Drag and drop multiple groups to the VIEW 2D axis system

[bienieck]

How to drag and drop multiple groups to the VIEW 2D axis system? I have an internal data with 80 groups, each has two channels: time (x-axis) and temperature (y-axis). I can drag and drop them one by one but can't in a batch 😕

To determine how to do something in DIAdem use two steps

• DIAdem Macro Recorder
• Pressing Ctrl+Shift+C in a configuration dialog which will copy code to clipboard which will show how to fill objects

Based on your last forum entry I created this script

Option Explicit
Call View.NewLayout()
View.Sheets(1).Areas(1).DisplayObjType = "CurveChart2D"

Dim oDisplayObj
Set oDisplayObj = View.Sheets("Sheet 1").Areas("Area : 1").DisplayObj
oDisplayObj.AxisLabeling = true
oDisplayObj.YScalingMode  = "automatic"

' assume we have a group of x/y channels stored in a group one after another
dim grpO : set grpO = data.Root.ChannelGroups(1)

' There might be some leading channels that do not need to be plotted like an index
dim channelPairOffset : channelPairOffset = 0
if "Item" = grpO.Channels(1).name then
  channelPairOffset = 1
end if

dim i
for i = 0 to ((grpO.Channels.Count - channelPairOffset)/2) - 1
  ' add curves to view by using x and y channel
  dim xChannelRef : xChannelRef = grpO.Channels(channelPairOffset + i*2 + 1).GetReference(eRefTypeIndexName)
  dim yChannelRef : yChannelRef = grpO.Channels(channelPairOffset + i*2 + 2).GetReference(eRefTypeIndexName)
  call oDisplayObj.Curves2D.Add(xChannelRef, yChannelRef)
Next

which will add x/y channels pairs from a single group to view.

Its is easy to modify to multiple groups but I would still suggest to put the channels in one group to make handling easier because DIAdem has no explicit X channels.

Just drag and drop a bunch of channels into View will plot them using the first selected channel as x-Channel which will result into the same as dragging a group with two channels where the x-Channel must be the first channel.

After creating such a View Layout you can just save it and just press Refresh after loading a new data file.

I cannot use the first channel as x-axis since every data channel (y) has its own timestamps (x). In another word, x is not common for all y.

You do not have to use the first one.

oDisplayObj.Curves2D.Add(xChannelRef, yChannelRef)

always uses a pair of channels but it does not matter where they are stored.

You can even use x channel from another group.

Just try the script in combination of the plugin of the other thread.
