[Solved]QAreaSeries not Showing up. Qt Charts

[Qt-Bot05]

I know I just posted recently but the other post was a bit dumb and I didn't try figuring out the problem first. Does this count as spam? I hope not.

In a Qt Designer UI I created a qwidget and promoted it to
Class Name: QChartView
Header File: PyQt5.QtChart.h

When I run the code below only a little box appears on the QChartView. (which I assume is the legend) But the QAreaSeries seems to be invisible.

Here's my current code

        up = QLineSeries()
        up.append(0, 10)

        down = QLineSeries()
        down.append(5, 50)

        series = QAreaSeries(up, down)
        chart = QChart()
        chart.addSeries(series)
        self.view.setChart(chart)

Tried Only having up. Didn't work.
But here's the thing. I tried appending in a bunch of random numbers for up and down. It worked clearly but it looked distorted. Maybe I just don't know what the heck I'm doing and don't understand QAreaSeries.

Anyways here's the random numbers.

        up = QLineSeries()
        up.append(0, 10)
        up.append(8, 69)
        up.append(4, 23)

        down = QLineSeries()
        down.append(5, 50)
        down.append(6, 21)
        down.append(1, 11)

I tried other different numbers but only some worked so clearly there's something I don't understand

Hi,

You have here an example of how to build an area series. It's in C++ but easily translated to Python.

I think it should provide you with the information you are looking for.
