Re: [Discuss-gnuradio] Matplotlib and GNU Radio: Dynamic plot

[Ali]

Hi,

Actually I want to draw coordinates on a map. So I want to upload a map(a png file, like using imshow function in MATLAB, matplotlib) and then draw points on this map. I think it is not possible by just using QT instruments. 

Regards,

Ali

Dear Ali,

don't convert data streams to Python variables. Just use the Qt instrumentation plots that directly come with GNU Radio, they are actually meant for this.

Matplotlib is *definitely* not what you want to use for live plots. Far too slow.

Best regards,

Marcus

Hi everyone,

I have a flowchart in which USRP's are running and after some blocks 2 variables are produced at the output.

As the inputs change, outputs change. I want to dynamically plot these two variables on x and y axis. I am willing to use matplotlib.

What do you suggest to plot these variables?

1- Write them to a .txt file and read by matplotlib at the same time,

2- Without writing the variable anywhere, directly use in matplotlib(somehow)

3- Write a python block and use in GRC directly

I don't know whether these can be applied or not. I am open to any ideas.

Regards,

Ali
