Change background color of Qcustomplot

The normal color is white. I can change the color in creator via a stylesheet change. I want to change it to yellow if data stops coming into the plot and back to white when data is coming into the plot

but when I compile and run that color is not on the plot.

I've tried the palette method and the stylesheet method in code via a button push. The color will not change. Since I promoted a QWidget to qcustomplot does my syntax have to include those items. This one has me frustrated.

Thanks for any help

I use:

Code:

---

m_CustomPlot->setBackground(QBrush(QColor("#b3daff")));

---

in C++. See if it works for you.

I tried it, it compiles but when running the color does not change. Are there some settings that lock the widgets defaults or something?

You *may* have to do a

Code:

---

->replot

---

to make it work.

Can we see your code?
