I am referencing the execute method: in line 71 of demo_ci.py.
I found when the execution result is a figure, the final variable 'msg_out' will be the code like:
{'code': "\n import matplotlib.pyplot as plt\n x = [1, 2, 3, 4, 5]\n y = [2, 3, 5, 7, 6]\n \n plt.plot(x, y)\n \n plt.title('Simple Line Plot')\n plt.xlabel('X-axis')\n plt.ylabel('Y-axis')\n plt.show()\n ", 'execution_count': 1}.

This will lead to: res_type = None, and res = '' in line 199.
Is this correct?

Expected behavior / 期待表现

I wonder how you display the figure in your demo
