Use index for xaxis when dragging multiple channels

When dragging multiple channels to view or to report, Diadem selects the first channel I click as the index.  This is fine sometimes, but most of the time, I would rather Diadem treat each channel I drag as y values.  Any way to do this? (Yes, I'm still using 2014...)

You might drop only a single channel (and thus the index is the xaxis) and then drop the other ones

Hello RussellSenior,

 

Typically, you draw a signal (Y channel) over reference values (X channel). This is often the clock rate (time), but can also be the frequency, length or something else. This is necessary to be able to plot, compare, calculate or analyze the data in a physical correct manner. But it is of course also possible to use just an index as X channel. In this case there is no reference to a physical quantity – the X channel is just a serial number.

In DIAdem we try to support an ease of use for the users and we try to support the mostly used situations. For VIEW and REPORT this is drag and drop for the channels. Currently we have the following options:

 

Simple numeric channels and plotting Y over X:

The first clicked channel is the X channel and all other selected channels are the Y channels

 

Numeric waveform channels and plotting Y over X:

Each waveform channel contains the X data in some channel properties so that these type of channel knows the reference. All selected waveform channels are plotted over its waveform data – the first selected channel is not used as X channel. (With reference to the waveform properties of a channel, DIAdem generates a hidden X channel in the background – for the user it is not necessary keeping attention to the X channel.)

 

Simple numeric channels plotting just a Y channel:

To be able to draw just a Y channel, DIAdem supports a special case. If you drag & drop just one Y channel (and this channel is not a waveform) then DIAdem generates a hidden X channel in the background. This is an index channel and for the user it is not necessary keeping attention to the X channel. This is only possible for a single selected channel. If you select more channels one of the above cases is used.

 

If you would like to draw multiple Y channels over the index you have two options:

Drag & drop each channel separate

Generate an index channel in ANALYSIS (channel functions, generate numeric channel) and the first option above can be used.

 

Greetings

Thanks. That confirms my findings.  

It would be handy if I could hold the ctrl key or shift key while dragging to tell Diadem I want all channels I'm dragging to be y values, and the x-axis be serial number.

Both key's are used for selecting options in the Dataportal. For this it is not possible to use them for drag&drop
