^ 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)));

Entry:

    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.
