In this article we will see how we can set tool tip to 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. The tooltip, infotip, or hint is a common graphical user interface element displayed as an informational text box when hovering over an item. The user hovers the pointer over an item, without clicking it, and a tooltip may appear a small “hover box” with information about the item being hovered over.
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
setToolTipmethod with the plot window object
Syntax : window.setToolTip(text)
Argument : It takes string as argument
Return : It returns None
Below is the implementation
