If we were to plot all our countries and their corresponding GDP and Years. the idea was not to complete the plot in matplotlib, but to modify the function in a relatively simple way to produce the points that constitute the straight line, defined by slope and intercept, within the upper and lower x-bounds of the data set. Now that Plotly Express handles data of both long and wide format (the latter in your case) like a breeze, the only thing you need to plot a regression line is: fig = px.scatter (df, x='X', y='Y', trendline="ols") Complete code snippet for wide data at the end of the question If you want to create multiple line chats on the same plot using plotly express, then you need to pass the name of the columns in list to the y axis. The added attribute labels=dict(x=Year, y=GDP) allows us to label our x and y axis. Python3 First, we need to import the Plotly express package. I know one can do this by adding a scatter trace with line mode and either finding the min/max (x,y) points or just adding the ys for all the xs one has for the line, but in some cases all one has is the slope and intercept and doing this manually every time is just such a waste of time. A line chart is a visual representation of data that changes over time. In this Plotly tutorial, you will learn how to plot log plot in Python. With px.scatter, each data point is represented as a marker point, whose location is given by the x and y columns. You can do it by specifying different columns of the array as the x and y-axis parameters in the matplotlib.pyplot.plot () function. If you take the built-in dataset px.data.gapminder as an example, you can trigger individual lines for an array of countries by specifying color="continent": And if you'd like even more flexibility with regards to model choice and output, you can always resort to my original answer to this post below.

What is the deepest Stockfish evaluation of the standard initial position that has ever been done? Much like our singular line graph, we can also edit the attributes of our individual line graphs in the stacked line chart. * if a lot of segmets are calculated, the graph complexity increases a lot as well Hi Johan did you finally find a concise method to achieve that ?

With px.line, each data point is represented as a vertex (which location is given by the x and y columns) of a polyline mark in 2D space. Using fig.data would create arrows for scatter points on the map too which I don't want. It is a great way to plot a 2D relationship.
