PyQtGraph – Setting Vertical Range of Plot Window
In this article we will see how we can set the vertical range of the plot window in the PyQtGraph module. PyQtGraph is a graphics and user interface library for Python that provides functionality commonly required in designing and science applications. Its primary goals are to provide fast, interactive graphics for displaying data (plots, video, etc.) and second is to provide tools to aid in rapid application development (for example, property trees such as used in Qt Designer).Plot windows consist of two main parts: the Plot Panel containing the actual plotted graphics and the Control Panel. Vertical range of the plot window is the range in which the view of vertical axis lies i.e y-axis. A chart has an y-axis range and a x-axis range to show the correlation between two different data sets. The y-axis is the vertical category line.
We can create a plot window with the help of command given below
# creating a pyqtgraph plot window window = pg.plot()
In order to do this we use
setYRangemethod with the plot window object
Syntax : window.setYRange(a, b)
Argument : It takes two integer as argument
Return : It returns None
Below is the implementation
