I'm trying to plot the price according to the longitude and latitude of the house. I want to add a colorbar, vmin=75000
and vmax=7700000
, but the scale with my code is from 1 to 1000000. How do I change that please?
My code:
fig, ax1 = plt.subplots()
fig.set_size_inches(16,10)
cm = plt.cm.get_cmap('RdYlBu')
# On crée ensuite notre figure
im= ax1.scatter(df["long"], df["lat"], c=df["price"], s=1, vmin=75000, vmax=7700000, cmap=cm)
fig.colorbar(im, ax=ax1)
# on ajoute les titres
ax1.set_title("Prix en fonction de la latittude et longitude")
ax1.set_xlabel("longitude")
ax1.set_ylabel("latitude")

One way to do this is to specify ticks for the color bar. You can change the colorbar line like this...
This will set the ticks at start of 7500, end at 7700000 and provide 10 ticks...
The colorbar should look something like this...
