DPlot

I didn't have anything handy, but this is such a great feature that I took the time to put something together for you Emailed!

I don't think "average x values" is right, because nothing is really being averaged here - at least not X.

Good point!

... the new label "Start at X=" entry isn't strictly correct either...

That depends on the user's input relative to their data set. :)

I'm not really all that interested ...

I actually don't remember how the forum works either :) I think it's any post on the topic but I'm not sure.

I completely agree that over x intervals is the way to go, regardless of what boxcar-ing actually means. I think you should call it "average x values..." rather than "group x values..." but ...

I can probably justifiably be accused of being hyperactive here...

No complaints about that here :)

Whoops! The last update calculated standard error as standard deviation divided by the number of points, rather than standard deviation divided by the square root of the number of points.

I was ...

I would also recommend adding "Boxcar averaging at ___ X-precision" in the same menu as when we are choosing the error bar type, because sometimes repeated measurements have slightly different x values. In case you don't know what boxcar averaging is, at 0.1 precision it would mean averaging all ...

I think you should change the name of the feature to "Generate Averages Curve With Error Bars" or something like that, and then we can choose whichever kind of error bar we want with a clickthrough menu. This feature alone would justify people buying dplot at the new price! Of course, I bought dplot ...

Standard Error of the Mean :)

It's the Standard Deviation divided by the square root of the number of measurements. http://en.wikipedia.org/wiki/Standard_error_(statistics)

You should probably also include the option of just the standard deviation since that's often used for the error in medical ...

This is a great feature, I actually just had to do this today using MATLAB, only what I needed was SEM! It's very common for me to do exactly what you did only to use SEM as the error bars. And I bet I'm not the only one, so if you add that as an option, it'll be really useful!

OH! I finally see what you mean!

Separate issue: When the color scheme is based on z values, the connecting lines are always black (unless there is an option I don't see).

Among other things, this means that printing in grayscale can look terrible unless you remove the lines (and of course ...

Oh you are right! I did not think of just making them into two series instead of 14. However, in the future you should still give us the ability to assign the colors manually for multiple series!

[In the mean time, this will still look good for my meeting once I change it]

I will tell you how I did it, but only if you agree to add the feature :)

I am just kidding, the way I did it was like this, I made an excel file with the following format:

Z1 X1 Y1 Z2 X2 Y2
1 ..... ..... 2 ..... .....
1 ..... ..... 2 ..... .....
1 ..... ..... 2 ..... .....
1 ..... ..... 2 ...

Ah! You're right. That is a completely reasonable solution.

Sometimes it happens with export to bmp, and sometimes it does not. I will email you the examples.

I am sure somebody has requested this already, but if you could get someone to help you with the code for generalized curve fitting (for an arbitrary function), I would no longer even bother buying a program like Origin or Sigmaplot, because then I could do virtually everything I need with Dplot and ...

I am using the 3D plot feature of DPlot to graph the change of a spectrum with time. Very similar to the following image:

http://sicyon.com/spectrino/screenshots/plot1.gif

However, what I am -actually- doing is comparing 2 sets of spectra across time. So I would like to make one set red, and one ...

Clarification: I was frustrated that we can only edit data series one point at a time (as far as I could tell)

What I meant is, it'd be nice to be able update the values of a single series without remaking the graph. If we could click "edit data" or "edit series" and then then paste the new x,y ...

Just came across this thread and wanted to remind you even though it's low priority, b/c it looks like you never got around to it

Do you know why the legend sometimes moves, depending on how we export it? Or rather... can you fix it? Sometimes I find that copying the picture from dplot and then pasting it to paint works best, and sometimes I find that exporting it works best.

Sometimes when I see what happens, I move my ...

Finally got it to work! Don't know what I did differently.

I tried again and my results have not been consistent, I'm e-mailing you the files to support@dplot.com

When we use the specified plot size, this looks fine on a screen, but when you print and look at it, or simply zoom in on it, the numbers of the axis look pretty bad, presumably since it's 75 dpi.

But if I use "Save as" and choose a high dpi, what comes out is completely messed up and useless.

So ...

I tried doing that fix, putting the file around various directories of those you've mentioned, doesn't seem to have fixed the error.

I did the unchecking the add-in, exiting excel, then restarting excel and checking the add-in again. Didn't work for me.

Will the next update of dplot automatically ...

How big is "null"?

The same as the y value divided by 0

It should show no error bars if it's null

When importing from excel, I had some cells which were blank due to having unknown error. E.g:
Y Error
1.1 0.4
1.2 0.6
1.7 0.3
1.8
1.9 0.4
3.4 0.5

When importing into dplot, the "blank" space is not imported. Now the error series has less datapoints.

When selecting the error series as the error ...

If the number of y data points is uneven when importing two separated columns from excel (as in, you need to hold ctrl to select them), the longer data gets truncated.

This only happens if the columns are separated, you use ctrl to select them, and if the last column is the shorter one.

Examples ...

David, thanks for adding in the update to the equal intervals command. It made subsequent interpolation easier.

I have another question/suggestion that just came up. One of the reasons I'm using the command is to take data sets which have arbitrary x-values, and to get them to "rounded" values

(e ...

I found it difficult to find as well, until I found it.

I'd like it if you could right click on a point to add error bars, or to add error bars for individual data points without having to choose a series. (e.g., copy and paste a list of points in). Same thing for editing a data series, I was ...

I've found that following DPlotAdmin's recommendation works well with a couple of modifications.

1) When using Options>Extents/Intervals/Size to "Specify size" for the box, make sure you take into account that this is only referring to the size of the graph box -- NOT including the axes titles. So ...
