Share a plot¶

A plot in a notebook needs the notebook's Python to draw. To show it to someone who does not run the notebook, save it as a page or as a picture.

As a page¶

save_html writes one HTML file with everything in it: the data, the code that draws it and the styles. It opens in any browser, also without a network, and stays interactive: pan, zoom, hover (with the tooltip= columns), Time / Order, folding traces and full screen. The plot fills the browser window.

plot.save_html("checkout-trace.html")

Several plots go in one page with anytimeline.save_html (save_html("page.html", plot_a, plot_b)); linked plots stay linked there.

Attach the file to a ticket, mail it, or put it on a web server. Selecting is the one thing it cannot do: that needs Python, which turns a selection into rows of your table.

The file holds all the data of the plot, so it grows with it: about 30 bytes per event plus the tooltip columns (tooltips are left out for layers of more than a million values).

As a picture¶

The toolbar's Save as PNG button (the arrow into a tray) downloads the plot as it is on screen: the title, the lanes and marks in view, and the legend, at twice the screen's resolution, named after the title. Zoom and fold first to show what matters.

From Python, save_png does the same into a file of your choice, also where a notebook blocks downloads (VS Code):

plot.save_png("checkout-trace.png")

The picture is drawn in the browser, so the plot must be on screen, and the file is written when the browser sends it: in Jupyter right after the cell has run.
