PyQtGraph – Setting X & Y position of Bar Graph
In this article we will see how we can set X & Y position of the bar graph 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).A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart. X & Y position of the bar graph is the position from which it start, by default it is 0, 0 although it can be changed any time.
We can create a plot window and bar graph with the help of commands given below
# creating a pyqtgraph plot window window = pg.plot() # creating a bar graph of green color bargraph = pg.BarGraphItem(x=x, height=y1, width=0.6, brush='g')
In order to do this we use
setYmethods with the bar graph object
Syntax : bargraph.setX(x) and bargraph.setY(y)
Argument : It takes integer as argument
Return : It returns None
Below is the implementation
