DPlot

The DPlot Forum update is complete. The database of forum users, posts, and content has all been successfully migrated to MySQL 8 and the forums now operate on phpBB 3.3. We have confirmed user credentials and other content from the previous forum database remain valid. There does appear to be one m...

The DPlot forums went down recently due to an unexpected upgrade by the website host to MySQL 8.0. The database has temporarily been moved to an alternate server to get the forums back online. We will be working over the next couple of weeks to backup and transfer the DPlot forums to a new MySQL 8.0...

Can you provide an example of the problem you are seeing? Or some sample data that produces this behavior? I cannot replicate the error you are describing without additional information or data to attempt to recreate what you are doing.

Thanks for the image. I am not seeing an easy way to adjust the curve label positions at the present time. However, this is a good suggestion to have an option to define an offset for the curve labels. I will look into adding this functionality in a future release. In the meantime, manually adding t...

Are you able to provide an image of the graph you are trying to add labels to? When I am plotting multiple curves in my work, I typically rely on legends with different curve lines and line or point patterns to distinguish between them. What you seem to be describing sounds more like text for a Poin...

Applied Research Associates, Inc. (ARA) is pleased to announce the acquisition of DPlot from Hydesoft Computing, LLC. ARA will be releasing an updated version soon and will send out an email to all past users when the new version is available for purchase and download. Until the new version is relea...

Please Note. From the author. Due to circumstances beyond my control, I am no longer able to support DPlot. Because I do not want it to simply fade away, I have sold the company and DPlot to another company. This is a reputable engineering and science research firm with an international presence. I...

The "Pick Columns to Plot" setting is persistent. If you select it once, it will by default be selected the next time you open a file - in this session or in subsequent sessions. However, you can get around this with ColumnsAre: FileType(4) ColumnsAre(0) ForFilesIn("*.csv") FileS...

No, sorry.

You can try Options>Amplitude Limits but it doesn't sound like that will solve the problem. My bet is there is a break in the data after line 4619 - say a blank line. Or some value that DPlot doesn't understand, so it stops reading. You should be able to find what is going on with Notepad, but a tex...

I received your file. Thanks for that. Unfortunately there won't be any significant changes to DPlot for quite a while, for reasons beyond my control.

On the Options>Multiple Axes dialog box, check the "For grid lines, use independent tick marks on dependent scales" box and see if that helps.

If not, please save your plot as a DPlot file and send it to me at support@dplot.com.

I'm a little confused about what you want to do. It sounds like you are exporting your data from Excel to DPlot and then using Info>Interpolate (or the InfoInterpolate macro command) to find Y on each curve for a given X. Correct so far? If so, you want to automatically export the results back to Ex...

One idea I had would be to interpret the .grf file as ASCII and parse any "Hide" lines to get this information, but this feels a bit patchwork if there are better options.

That's the only way that I can think of.

Same answer as before.

By default it sets the scale factors such that the physical distance along the X and Y axes is the same, and the distance along Z is approximately 1/2 of that. This generally fills the display nicely.

My go to app for testing metafile weirdness has always been Powerpoint, but this works fine there. I don't have the applications you mentioned. It sounds like whenever there is a font change, they reset the position of the text to the starting point. There is no (good) reason for this. I hate to dis...

I'll take a look asap.

Good catch. At first glance it appears the Point Labels dialog is not interpreting time values for the label location correctly. And in playing with this just a bit, it appears to only be fouling up if the X axis number format is "Time of day (fractional days)". It works fine with "Ti...

Are there any keywords that I should use or avoid? Those listed here: https://www.dplot.com/help/index.htm?dplotfilemiscellaneousidentifiers.htm shouldn't be used. Does it matter if I add it before or after the "STOP" ? After is better, Otherwise you may get an "unrecognized keyword&...

1. Unfortunately "Use as Legend" only works when you open multiple files OR when you're appending to an existing graph (where there is already a "Curve 1"). 2. Sorry, no. And this will not likely happen with macros. 3. ColumnsAre(0) will get rid of that dialog box and use all col...

Thanks.

If the sizes are the same then the plots will still only be centered on each other if the fonts are the same size and the labels (especially along the Y axis) are the same width. Another problem might be that one or more of the plots don't quite fit on the page within your specified margins. In that...

Mike,
There's no way to circumvent the behavior once an error has occurred. And within the macro there's no way to branch if some condition isn't met, like

if len(VAR_A) > 0 then
' do your normal thing
else
' do something else
endif

So... sorry!

Not really. About the best you can do is write a short macro and assign a shortcut key to it. For example this: LineType(-1,0) ' Sets ALL line styles to None SymbolType(-1,288) ' Sets ALL symbol styles to filled-in circles Of course if you don't want to do this for all curves then you'd need to be m...

The number of curves is limited to 100. This is a hard rule that likely will not be changed.

If I'm doing a 1D plot (boxplot), then in the command
DPlot_Plot8(dMyPlot, dX(0), dY(0), strPlotCommands) is it using dX or dY as the variable to plot. Does it ignore dX...

Yes. See http://www.dplot.com/lib/index.htm?dplot_plot.htm

Unless I miss something, you have not assigned the data values. So DPlot is getting a lot of undefined numbers (probably but not necessarily 0's). If that is the problem then there is likely an untrapped divide by 0 error in DPlot where it attempts to scale everything.

The OverlayDocument macro command is the only way, at present. 2D on 3D should work fine. You'll likely run into problems is you attempt to superimpose 2 3D plots.

Since it is the same curve, the total volume (above + below) should be the same irrespective of the specified Z. Is it not? The short answer is "no". Imagine if the reference Z was, instead of -1, -100. The volume below will still be 0, The volume above is a large(r) number, which is corr...
