Plots In Qt
Posted By admin On 17/07/22This series of blog posts details the creation of a custom Qt application containing an interactive matplotlib widget and a plot selection list, which controls the currently displayed figure. In Part 1, we constructed our application framework and layout using Qt Designer.
- Simple drawing plot in Qt Graphics View Framework. Contribute to DancingOnWater/GraphicsScenePlot development by creating an account on GitHub.
- 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.
A simple plot can be created with the module pyqtgraph. Mind you, it’s one of the libraries for plotting, there are others like matplotlib.
We start with importing pyqtgraph and defing the plotting data (x and y). Then we plot the data using pg.plot().

pyqtgraph plot
The example below creates a plot using pyqtgraph.
We can set additional properties of the chart like the labels, add a legend, the colors.
The output will look like this:
In code its like this:
Qt Data Visualization module provides a way to visualize data in 3D as bar, scatter, and surface graphs. It is especially useful for visualizing depth maps and large quantities of rapidly changing data, such as data received from multiple sensors. The look and feel of graphs can be customized by using themes or by adding custom items and labels to them.
Qt Data Visualization is built on Qt 5 and OpenGL to take advantage of hardware acceleration and Qt Quick 2.
Getting Started
Qt 3d Plot
To import Qt Data Visualization QML types, add the following import statement to your .qml
file:
If you intend to use Qt Data Visualization C++ classes in your application, use the following include and using directives:
Note: If you are only using a few classes from this module, we recommend including only those specific classes instead of the whole module.
To link against the Qt Data Visualization module, add this line to your qmake
project file:
