This is my first post and is similar to this one (Different marker shapes in 3d scatter plot), but I can’t seem to get anything to work in python. First off, I am trying to make a multi-line graph (which I have done in both plt and plotly…code below), but being colorblind (which I am) I can’t often tell what I am looking in plotly because the markers are always a circle (even though the label is included, it sometimes gets cut off and I can’t figure out what I’m looking at).
I am using Jupyter Notebook ##(version: 5.4.0)
Python ##(version 3.6.4)
Screenshot of the dummy_data file.
In matplotlib, I did the following to get the output attached (note the different shape markers):
import matplotlib as mpl ##(version: 2.1.2) import pandas as pd ##(version: 0.22.0) import numpy as np ##(version: 1.14.0) import plotly.graph_objs as go from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot import cufflinks as cf ##(version: 0.12.1) init_notebook_mode(connected=True) cf.go_offline() %matplotlib notebook fx = df.groupby(['studyarm', 'visit'])['totdiffic_chg'].mean().unstack('studyarm').drop(['02_UNSCH','ZEOS']) valid_markers = ([item for item in mpl.markers.MarkerStyle.markers.items() if item is not 'nothing' and not item.startswith('tick') and not item.startswith('caret')]) markers = np.random.choice(valid_markers, df.shape, replace=False) ax = fx.plot(kind = 'line', linestyle='-') for i, line in enumerate(ax.get_lines()): line.set_marker(markers[i]) ax.legend(loc='best') ax.set_xticklabels(df.index, rotation=45) plt.title('Some Made Up Data') plt.ylabel('Score', fontsize=14) plt.autoscale(enable=True, axis='x', tight=True) plt.tight_layout()
I used the code below and it created the graph via plotly/cufflinks:
fx.iplot(kind='line', yTitle='Score', title='Some Made Up Data', mode=markers,\ filename='cufflinks/simple-line')
I have searched the web for the last few days and I can see many options to change the color, opacity, etc., etc., but I can’t seem to figure out a way to automatically and randomly change the shape of the markers OR to manually change each individual line to a separate marker shape.
I am sure this is a simple fix, but I can’t figure it out. Any help (or nudge in the right direction) would be very much appreciated.!
