DPlot

David,

I thought DPlot can handle many millions of data points as long as the total memory needed won't exceed 2G.

You're welcome. But just so we're clear: the limitation here isn't so much ...

Hi! I'm trying to open a large (~ 1GB) XYZ 3D data to generate a contour plot. This message "Error triangulating data" pops up in the middle and DPlot failed to plot anything afterwards.

Could you please give me a clue to plot my data? There's no issue at all when plotting relatively small XYZ ...

OK. Please add a notice in the manual or help info in the next release to prevent this issue.

However, I did send the commands from another program (C), not just running the macros.

Just found out that the two macro commands (SelectCurve, EditOperateY) cannot be sent separately for what I wanted to do. Everything works fine now when I concatenate them and send as a whole command string together.

[SelectCurve(LegendHas("abc"))][EditOperateY("Y/17")] <-- works on one curve w ...

This is what I did:

[SelectCurve(1)]
[EditOperateY("Y/17*9.1")]

[SelectCurve(3)]
[EditOperateY("Y/17*9.1")]

The two operations on Y both changed the value of curve-1, not on curve-3. I will send you the plot soon.

OK. Now here's another prolem.

I use SelectCurve(LegendHas(...)) macro to select a specific curve based on the legend for further operation. But it's always the first cuvre in my plot being selected no matter what string I put in the LegendHas(...). Any trick to make this work?

I found ...

Is there a way to use SelectCurve(...) macro function to select multiple curves simultaneously, but not all of curves in a plot?

Something like this SelectCurve(1,3,5) to select curves 1, 3, and 5 for further operation.

"... perhaps I'll allow multiple selections with the Histogram command in a future release." --- Please do so. This is very much desirable!

I have two columns of data (both columns are Y values) that I'd like to plot their histograms side by side in on chart. How can I do it? The "Generate --> Histogram" menu command only allows me to select one cuve at a time and the histogram will be created in two separate charts.

No. I didn't have Excel running in the background.
I realize it's Microsoft Lync that causes this problem. I need to terminate it before a successful installation.

When I install the latest DPlot (version 2.3.3.9) on my XP PC, the following errors pop up during the setup:

1) Microsoft Visual Basic
Run-time error '13'
Type mismatch

2) Error
C:\Program Files\DPlot\addin\DPlotLIB.XLA
An error occurred while trying to read the source file:
The process ...

Thanks! That works. Hope you'll fix this issue in the next release.

OK. The note can be added. It looks like the label now.
But the "Specify extents" box is checked and the last value still won't show. I will e-mail you the graph to take a look at. Thanks!

1) How can I display the label of Z-axis in a XY contour plot?
2) The low and high value of the X-axis is 3.2 and 4.8 on my plot. The tick mark interval of the X-asix is 0.2. Why isn't the last value (4.8) shown in the plot while the others (3.2, 3.4, ... 4.6) are?

You're right! It works only when I manually open the file using File>Open.

But, again, if the same data folder (with a + sign in the folder name) is placed in a local drive, everything (drag&drop, double click...) works perfectly.

I have a text data file (filename data1.txt) contains these values:

X(nm) Y1(uW)
1.2 1.4
2.6 4
3.9 16.2
5.7 23.5

When this data file is placed in a remote network folder "\\Epsilon\Testing\temp\Fod2.0\try_DC&IV_K1", DPlot can open/plot it and drag-and-drop works just fine. However, if this ...

This problem is fixed in the newer version of DPlot (2.3.2.6) as you said. Thanks a lot!

Hi! David,

Just send you the data file. It has exactly the same content as what I posted here. Thanks!

Hi!

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

/sm OFF
/sc ON
/sd OFF
/td "xy"

1351.0 -65.105775
1351.35 -65.042302
1351.7 -64.955354
1352.05 -64.981671
1352.4 -65.012926
1352.75 -64.88401
1353.1 -64.843886
1353.45 -64.893882
1353.8 -64.841875
1354.15 -64.665983
1354.5 -64.677306
1354.85 ...

Hope this limit can be removed soon.....
Thanks!

Hi!

Is there a way to remove this 9 curves limit? I have 12 curves....

OK. That works for me. Thanks!

Hi!

Could you please implement a header command that tells DPlot to plot only certain selected columns when opening a data file? Instead of doing it manually using the "Pick Columns to Plot" check box, a command line in the header portion of a data file should let DPlot do it automatically. Such ...

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!

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

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 ...
