PyQtGraph – Rotating Data of Spots of Scatter Plot Graph
In this article, we will see how to rotate the data in a scatter plot graph in the PyQtGraph module. The 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.). A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. It is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Data get changed due to the rotation, rotation happens based on the axis.
We can create a plot window and create scatter plot graph on it with the help of commands given below:
# creating a pyqtgraph plot window plt = pg.plot() # creating a scatter plot graph of size = 10 scatter = pg.ScatterPlotItem(size=10)
In order to do this, we use setRotation() method with the scatter plot graph object.
Syntax : scatter.setRotation(n)
Argument : It takes float value as argument
Return : It returns None
Below is the implementation:
