DPlot

David,
Hate to see the change, but I understand. I think I retired about the same time as you did, so I only use the software occasionally. But I did leave behind some younger engineers who got hooked on DPlot, so I hope the new company can support them.
Regards,
Jon

I think I have had similar situations, Win7x64, even w 8gb memory, and several large plots open. I would try to save carefully, and if I "got lost" because I wasn't sure what plot that I was dealing with, I would close everything and just start over. I never was so clever as to try to redr...

David,

Ignore above. First step in trouble shooting is to not load some of my "TSR" utilities, esp. AltMove Manager, WizMouse, and CrossHair - anything that has to do with the mouse.

David, Thanks. That works, but I have to tell you that lately every time I touch DPlot, I get a new glitch. After I copied the truncated curves back to my original plot, I next did a "Find Intersections" between that line and the longer line that I had not truncated. The command completed ...

Okay, there is a "Split at Y" in the generate menu. Is there an easy way to split a curve at an "X" position. I'm rusty - maybe I forgot a method that I should remember, but I'm not finding a menu entry or in the help. I guess one way to brute force it would be to copy a curve, t...

Nope, can't do that - I want to delete points that are some distance apart. It would help if I could adjust the scan "rate" like you can do in the "Scan Data" dialog. Or better yet, some kind of filter that would work on these GPS traces that have some "backtracking" in...

David, I'm using Edit Mode on a large gps trace to clean up some spikes in the data. Edit Mode is great, and I remembered the "Delete" button (!), but is there a way to do more than one point at a time? After I click delete, I have to click OK to close the dialog before clicking the next p...

Yes, I've been called stubborn before - half Italian and half German - I can be stubborn with a passion! I was just trying to understand why a curve cut off in the middle of my plot - was my fault for using YCutoff in the macro! And working with the large data sets, I had to pre-set the arrays to al...

I think I found a DPlot limit - it's not liking 11 curves with 5,320,130 points each! And while investigating why a curve just seemed to "stop" 1/2 of the way through the time scale, when I did an "Edit Data" on one of the curves, I realized that the row labels in the edit box on...

Yes, I just noticed this as well, wondering if I changed some setting someplace. David, regardless of the Excel 2013 append-fix status, are you planning on a bug fix release in the near future? We are no higher than Excel 2010-32bit here at work (and I'm still getting away with 2007 because I refuse...

I may have asked about this before, but will try again if I haven't. In the status line, you now show X, Y, and Y2 if there is a Y2 axis defined. How about showing X2 if there is an X2 axis defined? There are several other places where the X2 and Y2 information would be helpful to see as well - scan...

Still would like this capability if at all possible! (ie, intersection of a real curve with a reference line, with any added points being added to the real curve.)

Thanks.
Jon

I think the command in a macro is:

Title1("$FILETITLE")

Which should assign the filename to the first line of the title block area.

Thanks, but runsum is not quite ready for prime time! (Definitely needs to be able to select a curve(s), and the generated curves are not labeled.) Guess I'll stick with what I'm doing. I have 4 or 5 data curves, and using stacked IF statements comparing Y values in several of the curves, I assign 1...

You must mean "Integrate a Curve". (There's no other "running total" command in 2.3.5.3??) Yes, I saw that, but didn't try it because I thought it acted "odd" the last time I played with it. But now I see it actually does do a SUMY() as I thought it should. But that pro...

David, I'd still like to do something like SUM("insert function") and not waste a curve. Or have more than 1-9 to work with for the number of curves. Something like 0-9 plus "A-F" perhaps. (or some other digit or symbol?). Any chance?? Thanks again.

David, in the label points dialog, there is a checkbox to "copy the above options to all existing labels". Seems like this refers to only the Frame, Vertical, Opaque, Mouse-activated, and color options. I was hoping it meant the Label option as well, but it seems it does not. (ie, I change...

Using Bar Chart (Label, Y1, Y2,...) from Excel 2007 I get what DWW describes, ie, the X-axis labels are set one set to the right. The label "Umbria" does not show on the plotted data - it's off screen to the right. However, it seems that the cause is the extra empty line between the first ...

And even when you force a reference line by temporarily changing the axis from a time to a number format, if you change the x-axis back to a time scale, you can't edit the position of the reference line - the line disappears. Not only that, what you thought you edited is some other value, "mile...

David- sorry for dredging up an old topic...

Have you given any more thought to increasing the number of curves available for equations/functions from the first 9 to more than 9? 15-20 would be great.

Thanks.

Not as expert with DPlot as I'd like to be, but unless David has some "trick" like multiplying the curves on Y2 by -1 (??), I'd say there is no way. Looks like the check box in Extents changes both axes.

(Well, I'm wrong again!)

Looks like checking "Step Placement > Backward" will do the trick.

Another thought about this function. (They're coming harder and harder...thoughts, that is.) Any chance of showing the x-position in the lower left status area before you click the first marker? And then let it show the 2nd x-position before the mouse button is released? It would enhance the ability...

Roberto, I just tried the step plot - yes it does seem to do what you want - change the extents to + and - values of what your data limits are (ie, -1 and +2_ - everything is "connected". (and previously, yes, I manually added the data points. I'd probably create a small basic program to m...

Roberto, Completely wrong impression of DPlot. DPlot plots the true X-Y data point, regardless of regular spacing or not. If you know the concept of line graphs vs. xy plots in Excel, then you should know DPlot is always in an "XY" mode of graphing. THE TRICK IS to make sure the data you a...

I didn't get a message about memory being exceeded, but I just tried allocating memory for another curve, and this time it worked, ie, Replace input was unchecked, so a new curve was added on top of the original curve. And I definitely had multiple Y's for many X's - I need to talk to the engineer a...

David, in 2.3.4.5, with this new function for averaging duplicate x's, if I DON'T check "Replace input", am I supposed to get a new curve? I've got a large dataset, the curve I'm working with has 4.6m points, and if I don't check the box, nothing seems to happen. There's no hidden curve ei...

I was thinking of doing that, and after I did, I got a bar chart that I don't quite know what's going on. Aside from my inability to fully comprehend the bar width and group width relationship, the bars on the right side of the plot aren't showing where I think they should show. I'll send an email w...

I just pasted a 1-D list of dates representing a failed part's build week into a blank window in DPlot. A date for every failed part. Then I asked DPlot to do a histogram with a 7 day interval. I got a bar chart and it looks correct, properly spread out over 3 years of production. But I would like t...

Guess I spoke too soon about "nothing happened". Data looked like it had multiple y's for x's, but it did not. Data was just packed tighter than I thought. I made up a test curve and inserted a couple of extra points, and it acted as you said. But yes, please, add the selection and request...
