Hi all, I want to plot 3D bathymetry from GEBCO data. I am attaching my code and plot below, can anyone help me in rectifying my code for proper plot of bathymetry. ''' ________________________ surface (color map) ====================== Demonstrates plotting a 3D surface colored with the coolwarm color map. The surface is made opaque by using antialiased=False. Also demonstrates using the LinearLocator and custom formatting for the z axis tick labels. ''' from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt from matplotlib import cm from matplotlib.ticker import LinearLocator, FormatStrFormatter import numpy as np from netCDF4 import Dataset as NetCDFFile fig = plt.figure() ax = fig.gca(projection='3d') nc = NetCDFFile('GEBCO_2014_2D.nc') X = nc.variables['lon'][:] Y = nc.variables['lat'][:] Z = nc.variables['elevation'][:] X,Y = np.meshgrid(X,Y) # Plot the surface. surf = ax.plot_surface(X, Y, Z, cmap=cm.coolwarm, linewidth=0, antialiased=False) # Customize the z axis. ax.set_zlim(-1.01, 1.01) ax.zaxis.set_major_locator(LinearLocator(10)) ax.zaxis.set_major_formatter(FormatStrFormatter('%.02f')) # Add a color bar which maps values to colors. fig.colorbar(surf, shrink=0.5, aspect=5) plt.show() <http://matplotlib.1069221.n5.nabble.com/file/t5155/Figure_1.png> -- Sent from: http://matplotlib.1069221.n5.nabble.com/matplotlib-devel-f28077.html

mpl_finance maintainer
by Adam Watson April 17, 2018

April 17, 2018

Hello, Are you still looking for a mpl_finance maintainer? I don't know if I have the credentials you're looking for but I've used Python for about 4 years now and am using the mpl_finance package a lot in my current projects, so I'd love to take on the responsibility if you still need someone. My GitHub handle is a-watson, but it doesn't have much on it. Thank you for your consideration! Regards, Adam Watson

plot markers with drawstyle='steps-post'
by Pierre Haessig April 12, 2018

April 12, 2018

Hello, I have noticed a change with line plots using drawstyle='steps-post' and markers. Using Matplotlib 2.2.2 (Conso_gaz_model.png) there is a marker at each "edge" of the line. In a previous Matplotlib version (2.1 or 2.0, cf. file Conso_gaz_model (copie).png), there was only a marker at the actual data point. Is this a well-known change or a regression ? (I've quickly looked at the issue tracker, but didn't find something) Best, Pierre

John Hunter Matplotlib Summer Fellowship 2018
by Thomas Caswell April 11, 2018

April 11, 2018

Folks, We are happy to announce that we will be supporting a summer student to work on Matplotlib this summer! The student will be writing a Matplotlib based renderer for Altair and primarily mentored by Hannah. Altair is a declarative statistical visualization library for Python, based on Vega and Vega-Lite. Currently Altair charts can only be rendered in the browser, so we are looking for a student to write a Matplotlib based renderer for Altair. This renderer would take in Altair objects and produce Matplotlib objects for integration with existing tools and to generate publication-quality figures. To apply, please submit a cover letter and resume/CV to matplotlib(a)numfocus.org by May 4, 2018. https://www.numfocus.org/programs/john-hunter-technology-fellowship for more details. Please distribute this to your networks! Tom
