Export Data to CSV Directly from Plot

[lars-nagel]

Summary

Add the ability to directly export time-series data to CSV from individual plots, respecting the current zoom level and selected data series.

Description

Currently, while the application offers a "Publishers -> CSV Exporter" feature and options to "Save plot to file" or "Show data statistics" (with "Calculate statistics from: Visible Range"), there is no direct way to export the raw data from a specific plot for only the currently visible/zoomed time range.

Proposed Feature

Add a context menu option (accessible via right-click on a plot) called "Save Data to CSV" or "Export Data to CSV" that would:

• Export only the time-series data currently displayed in the selected plot
• Respect the current zoom level (only export data within the visible time range)
• Provide a flexible, per-plot export workflow

Use Case / Motivation

This feature would enable users to quickly extract specific subsets of data from their plots without having to:

• Export all data and manually filter it
• Lose the context of their current visualization state

This is particularly useful for:

• Sharing specific time windows of data with colleagues
• Further analysis of zoomed regions in external tools
• Documentation and reporting purposes

In any case, thank you very much for developing this great tool!

I prototyped how I imagine this feature here: #1219.

Thanks for the prototype. the idea is great, but as I mentioned in the PR, I have a better plan that includes a new "Export toolbox" that will include CSV among other formats.

I am closing this as "wontfix", but thatnks a lot for the idea!!
