These examples show how to create line plots, scatter plots, and histograms in polar coordinates. They also show how to annotate and change axes limits on polar plots. Create Polar Line Plot Visualize the radiation pattern from an antenna in polar coordinates. Load the file antennaData.mat, ...
Plotting with polar coordinates All the plots in this chapter up to now have implicitly used rectangular coordinates, usually denoted as x and y. For certain types of information, however, polar geometry is the natural coordinate system. In polar coordinates we have a radius, r, measured from ...
A polar radius and a polar angle of the point in polar coordinates are recorded. The stepping motor is made to drive the guide rail to rotate for a circle in order, and equipotential points in different directions are measured, so that the equipotential line can be plotted, and other ...
To give you some numbers: A line plot with 500.000 points can be fluidly handled on today's desktop machines. This not only means dragging but also zooming, rescaling etc., because QCustomPlot's new plotting technique doesn't rely on simple pixmap buffering. It maintains full flexibility in ...
The interface of the NodeSegment control is expressed in terms of a centre point, radii and angles, i.e. a polar coordinate system. Whereas, the Path shown above which has been added to the control template expects points to be expressed as X and Y locations, i.e. they use the ...

size will be the absolute font size in points. String values are relative to the current default font size. This argument is only used if `prop` is not specified. numpoints : None or int The number of marker points in the legend when creating a legend ...
When this angle is obtained, a distance to the reference point can be obtained and consequently the coordinates of the origin of a scanning coordinate system are obtained (S5). Since the coordinate values of the respective reference points in the scanning coordinate system are obtained based on ...
