YQ Tsui 2f5ce3dc01 Plot enhancement (#1390)
* horizontally put the bar figures

* 1) use rangebreaks to handle gaps in datetime axis instead of make them string; 2) allow simultaneously plot rankic in ic_figure

* pylint improvement

* fix black lint

* better axis formatting

* default not show gaps

* resolve doc built error

* fix pylint

* Update qlib/contrib/report/analysis_model/analysis_model_performance.py

More detailed description

* Update qlib/contrib/report/analysis_model/analysis_model_performance.py

for Python backward compatibility

Co-authored-by: you-n-g <you-n-g@users.noreply.github.com>

* add doc string

* fix black

* 1) limit numpy version as numba support for 1.24+ has not been released; 2) no need to use custom numba version for pytest.

it will return a generator, each row contains <col_n> sub graph
FIXME: Known limitation:
- The last row will not be plotted automatically, please plot it outside the function
Parameters
----------
sub_fs :
the figure size of each subgraph in <col_n> * <row_n> subgraphs
col_n :
the number of subgraph in each row; It will generating a new graph after generating <col_n> of subgraphs.
row_n :
the number of subgraph in each column
wspace :
the width of the space for subgraphs in each row
hspace :
the height of blank space for subgraphs in each column
You can try 0.3 if you feel it is too crowded
Returns
-------
It will return graphs with the shape of <col_n> each iter (it is squeezed).

This function `guesses` the rangebreaks required to remove gaps in datetime index.

----------

the `rangebreaks` to be passed into plotly axis.
