Usage of data visualization in Thonny [Copy link]

 

First, in Thonny's view menu, check plotter.

Then in the program, print out the data you want to visualize, and Thonny will automatically determine the printed value and draw the plot. The printing method is

print(name, dat)

• name is the name of the data, which can be any string, or you can leave name unset and just print dat.
• dat is the data to be plotted, which can be an integer or a floating point number. You can print multiple values at a time, and each value will be displayed in a different color.
• Be careful not to insert other print statements, as this will cause data plotting errors and failure.

Taking the pyboard's accelerometer as an example, run the following program:

import pyb

acc = pyb.Accel()
while 1:
    print('x', acc.x(), 'y', acc.y(), 'z', acc.z())
    pyb.delay(500)

When plotting data, the value range is automatically detected and appropriate processing is performed to make the display clearer.

When I use thonny, I often encounter the situation that pyb suddenly stops responding during the download process. After reinserting it, it can be used again. What's going on?

I haven't encountered this problem yet. Try a newer version.
