""" | ||
It uses plotly.express.line. | ||
Each data point is represented as a marker point, whose location is given by the x and y columns | ||
of self.data. | ||
Parameters | ||
---------- | ||
y: str | ||
Y axes, column or index of data. | ||
x: str | ||
X axes, column or index of data. | ||
color: str | ||
Name of a column or index of data. Values from this column are used to assign color to | ||
marks. If color = 'auto', color = QC column of y. | ||
range_y: list | ||
[min value, max value] of y axes. If range_y = 'auto', range is generated between the | ||
mina nd max values of y axes +- 5%. | ||
line_shape: str | ||
Line options: 'linear' 'spline', 'vhv', 'hvh', 'vh', 'hv' | ||
rangeslider_visible: bool | ||
Show a time range slide on the bottom x axes. | ||
line_group: str or int or Series or array-like | ||
Either a name of a column in wf.data, or a pandas Series or array_like object. | ||
Values from this column or array_like are used to group rows of data_frame into lines. | ||
resample: str | ||
Get the plot with resample data. If resample, color = 'DEPTH' | ||
view_maxmin: bool | ||
Show the max and min values if data is resampled. | ||
trend: bool | ||
Show a linear regression of the trace. | ||
**kwds: keywords | ||
plotly express scatter keywords. | ||
