Frequently Asked Questions
Can I open projects made in legacy Sma4Win?
Yes. SmaPlot reads native .SMP project files including plot bounds, series data, 4-axis configurations, annotations, and text formatting.
Can I export back to Sma4Win .SMP format?
Yes. Exporting saves files with standard .SMP structure and markers so legacy software can read them seamlessly.
Is my data uploaded to any remote server?
No. All data processing, curve calculations, and file rendering run entirely on your local machine within the browser.
What devices are supported for running SmaPlot?
SmaPlot runs optimally on desktop computers (Windows, macOS, Linux) and tablets. It can also be accessed and used on smartphones, though navigating the workspace may feel constrained due to smaller screen sizes.
