Description
Greeting!
I am a newbie in Python, and I greatly appreciate this brilliantly made built-in package for visualization of yfinance data.
I am learning and trying to plot the Ichimoku Cloud Chart, and found that the plot displayed would show with the x-axis limited at the latest data date, while the Ichimoku indicator actually would plot the cloud area 26days into future.
I tried to extend the x-axis using the xlim() function to extend 1 month into future, but the cloud still is not shown in the plot.
I have checked and make sure that in my calculations, the shift() function is applied to the calculation of the 3 lines, Leading Span A, Leading Span B, and Lagging Span. Thus I believe that there would be data to be plotted for the future date.
The first chart below is the plot generated from my broken code.
And the lower chart is a chart I got from a free online platform. I target to make my plot look more or less like this.
May I get help on how I can correctly plot the cloud for the Ichimoku chart?
Thanks in advance.
This is the chart plotted from my broken python code

Research direction
The issue mentions mplfinance plotting, xlim(), and shifted Ichimoku lines, but provides no source file, runnable example, or test to start from. Reproduce the reported chart behavior with the supplied screenshots and determine what complete future cloud rendering should look like before adding a regression test.
