[FEATURE] Graphical Demonstration of Relative_Loading on dash_plot

[batuhansanliii]

The relative loading of lines on the graph is depicted based on the following calculation:

eDisGo/edisgo/tools/plots.py

Lines 1219 to 1226 in 9fae3ea

	elif line_color == "relative_loading":
	loading = s_res.loc[branch_name]
	s_nom = edisgo_obj.topology.lines_df.s_nom.loc[branch_name]
	color = color_map_color(
	loading / s_nom * 0.9,
	vmin=color_min,
	vmax=color_max,
	cmap_name=colorscale,

However, the calculation of relative_loading of the lines is done as follows:

eDisGo/edisgo/flex_opt/check_tech_constraints.py

Lines 190 to 215 in 9fae3ea

	def lines_relative_load(edisgo_obj, lines_allowed_load):
	"""
	Calculates relative line load based on specified allowed line load.
	Parameters
	----------
	edisgo_obj : :class:`~.EDisGo`
	lines_allowed_load : :pandas:`pandas.DataFrame<DataFrame>`
	Dataframe containing the maximum allowed current per line and time step
	in kA. Index of the dataframe are time steps of type
	:pandas:`pandas.Timestamp<Timestamp>` and columns are line names.
	Returns
	--------
	:pandas:`pandas.DataFrame<DataFrame>`
	Dataframe containing the relative line load per line and time step.
	Index and columns of the dataframe are the same as those of parameter
	`lines_allowed_load`.
	"""
	# get line load from power flow analysis
	i_lines_pfa = edisgo_obj.results.i_res.loc[
	lines_allowed_load.index, lines_allowed_load.columns
	]
	return i_lines_pfa / lines_allowed_load

As you can see from the example in the attached ipynb. file, the relative loading of example branch is bigger than 1 but shown smaller than 1 on the graph

I think you are still using an old branch, as the plotting function is now called plot_dash(). Please pull the current dev into your branch. But anyways, you are right, it is currently not quite consistent. In PR #290 I am working on this. However, your bug should be fixed already on dev.

I updated the branch. Now it is better working.
Thank you
