^ QCustomPlot references
Notes and links relating to QCustomPlot sofware, second link here is to the starting or main documentation page for QCustomPlot classes and their relation to Qt classes and code framework:
Code snippet from basic plotting tutorial:
// add title layout element:
customPlot->plotLayout()->insertRow(0);
customPlot->plotLayout()->addElement(0, 0, new QCPTextElement(customPlot, "Way too many graphs in one plot", QFont("sans", 12, QFont::Bold)));

Information about insertRow() and addElement() functions, the first of which appears in very few search results using Google, but which seems related to the much more oft mentioned addRow() Qt5 library routine:
Information about saving QCustomPlots to file:

French lavender starts in four-inch starter pots, for sale by Milwaukie area gardener. Selling for three dollars ($3) a start.
A Mediterranean native, French lavendar (lavendula stoechas) once established is extremely drought tolerant. Under normal conditions in Portland area, no need to water or fertilize this plant after its first year in the ground.
Likes full sun, and open space with good air circulation. Attracts bumble bees, honeybees, and orchard mason bees.
This plant grows for several years, it is perennial. Older plants may need be replaced from time to time, if a larger branch or branches should break. Slow to moderate growth rate. Not always able to fill in a void if a branch breaks near the plant's base.
Cash-only sales and PayPal accepted. If you have questions about these plants feel free to write us and ask.

Excerpt from https://www.history-a2z.com/abandoned-places/13/?xcmg=1 . . .
Fishing Hut On A lake In Germany Deep within the mountains of the Berchtesgaden National Park sits a deserted old fishing hut resting on the waters of the Obersee Lake. By the time it was rediscovered the hut had been completely emptied with no signs as to who the previous owners were or when it was built. Nestled in such beautiful scenery, you can imagine the joy it must be to sit in total peace and quiet and fish from the surrounding waters.
