Drag and drop to plot multi-column data

Hi!

I have a simple multi-column data file like this:

X Y1 Y2 Y3 Y4
1 2 3 4 5
2 4 6 8 10
3 6 9 12 18

It is saved as a text file named "data.txt"

Everytime when I drag and drop this file into a opened empty DPlot Viewer, it always plot 5 curves instead of 4. The first column is always recognized as a Y-column instead of an X-column.

I've set the "Pick Columns to Plot" and assign column-1 manually to plot as what was described in the previous subject (http://www.dplot.com/forums/viewtopic.php?t=994&highlight=drag+drop). It works fine and plot 4 curves correctly if the DPlot Viewer is not closed. But when DPlot Viewer is closed and re-opened, this problem comes up again. It is not persistent at all.

Is there a way to add a format line (something like XYY) somewhere in this simple data file to tell DPlot Viewer to plot it correctly? I know in the help file it says DPlot uses the first column as X-column by default, but it doesn't when you use "drag and drop" to plot the simple data format. Could you please fix this problem? Many thanks!

Fixed. Thanks for the heads up. I'll likely post an update this coming weekend.

Great! So it will be in the 2.3.1.0 version, right?
Really looking forward to it......

Yes on the version number. Sorry it didn't make it last weekend, but it will be coming soon.

Ah! The long-awaited drag-and-drop function is finally fixed.
Now my director won't have more excuses not to sign the PO to purchase DPlot. Thanks a lot for the new 2.3.1.0 version!
