Data in a sheet,a figure beside it

The application

Import,fit, then lay out

A spreadsheet, a fitting engine and a worksheet in the one window.

It reads your columns

CSV, fixed-width, HDF5, NetCDF and FITS land in a sheet you can edit.

Fits with the errors

Non-linear fits report parameters and uncertainties, not just a curve.

Print-ready worksheets

Axes, insets and annotations arranged for a page, exported to PDF or SVG.

How you run it

Every defaultis one override away

The session reads its settings from the environment, so you set them on the start line.

VNC_PASSWORDWhat the tab asks for. It ships as dxflow, and everyone reading this knows that.

PANEL and TASKBARBoth hidden, so the worksheet has the whole screen. Show either one to get the desktop back.

AUDIOOff here. Turn it on and the desktop sound is streamed beside the picture.

start it your way

Good to know

Put the datawhere it can find it

LabPlot reads from disk, not from your laptop. Upload first, then import from the volume.

Import from /volume

CSV, fixed-width, HDF5, NetCDF and FITS all come off the volume. Upload them before you start hunting in the file dialog.

Built on Void

A small desktop underneath, so the image stays light for something that draws for a living.

Projects and exports persist

The project file and whatever PDF or SVG you export stay under /volume between runs.

The image

Pulled once,then it stays

LabPlot arrives as one image. This is what comes down the first time, and what the disk should have free for it.

What it asks for

What it wants,and what it needs

The definition asks for 2 cores and 4 GB. The image comes up on less than that, and a start given --fit trims the ask to whatever the machine actually has.

2 cores · 4 GBAsks forwhat the definition writes down

2 cores · 2 GBRuns onthe least the image comes up on

Not neededGPUit works on the cores alone

The ask is not the floorThe definition writes down what suits the work. The image itself starts on less, which is what the second figure is.

--fit caps it to the hostA start given --fit trims each step to what the machine actually has, for that start alone. The definition is never rewritten.
