The goal ist to:
plot data based on a dropdown value
have multiple plots based on the same value
align them in a row (horizontal).
In my case the interactive_plot is the box with all plots in it, therefore I can't style them how I want it. How do I plot the two plots in one line?
def showMADetails(column=filter_unique):
plt.figure(1)
filtered_ma = ma_data[(ma_data['2'] == column)]
plt.bar(column, filtered_ma['GrossTurnoverBudget'], align='center', alpha=0.5)
plt.figure(2)
filtered_ma = ma_data[(ma_data['2'] == column)]
plt.bar(column, filtered_ma['Productive billableDays'], align='center', alpha=0.5)
interactive_plot = interactive(showMADetails)
output = interactive_plot.children[1]
output.layout.height = '400px'
output.layout.width = '200px'
interactive_plot
figured out that I was wrong. The plots aren't widgets, so I followed a wrong approach.
The interactive_plot controls the UI of the widgets.
To control the plots itself I need to control the layout via subplots. That is the solution.

I am using the following lines of python code to create a figure with multiple subplots in a Jupiter notebook and attempting to add colorbars to some of the plots. The following lines are 1 of 7 sections copied and pasted with adjustments to GridSpec, variables, labels and axes handles made for each:
fig = plt.figure(figsize=(20,20))
gs = gridspec.GridSpec(21, 13)
...
if i >= 1:
ax3 = plt.subplot(gs[6:9, 3*i+1:3*i+4],projection=ccrs.Robinson())
else:
ax3 = plt.subplot(gs[6:9, 3*i:3*i+3],projection=ccrs.Robinson())
if i == 0:
cs3 = ax3.contourf(Lon,lat,cldhgh.squeeze(),12,transform=ccrs.PlateCarree(),cmap='gist_gray',vmin=0,vmax=1)
ax3.coastlines()
Cticks=np.around(np.linspace(0,1,6),decimals=1)
Cbar_ax3 = fig.add_axes([0.3,0.58,0.01,0.10])
cb3 = fig.colorbar(cs3, spacing='proportional',orientation='vertical',cax=Cbar_ax3,ticks=Cticks)
#cb2.set_ticklabels(Cticks.astype(int).astype(str),fontsize=7)
cb3.set_ticklabels(Cticks.astype(str),fontsize=12)
cb3.set_label('High Cloud Fraction',fontsize=10)
else:
cs3 = ax3.contourf(Lon,lat,delta_cldhgh,61,transform=ccrs.PlateCarree(),cmap='BrBG',vmin=-0.2,vmax=0.2)
c3 = ax3.contour(Lon,lat,cldhgh.squeeze(),12,vmin=0,vmax=1,colors='black',linewidths=0.5)
ax3.coastlines()
if i == 1:
cticks=np.around(np.linspace(-0.2,0.2,5),decimals=1)
cbar_ax = fig.add_axes([1.02,0.58,0.01,0.10])
ax3.set_ylabel('Hybrid Sigma-Pressure level (mb)',fontsize=12)
#cb = fig.colorbar(cs, spacing='proportional',orientation='vertical',cax=cbar_ax,ticks=cticks)
cb3 = fig.colorbar(mappable=None, norm=Normalize(vmin=-0.2,vmax=0.2), cmap='BrBG',spacing='proportional',orientation='vertical',cax=cbar_ax,ticks=cticks)
cb3.set_ticklabels(cticks.astype(str),fontsize=12)
#cb2.set_ticklabels(cticks.astype(int).astype(str),fontsize=10)
cb3.set_label('Cloud Fraction Difference',fontsize=10)
...
plt.suptitle('Comparison of mappables of Background Climate States',fontsize=24,y=1.01)
#fig.text(-0.04, 0.5, 'Sigma Pressure Level (mb)', va='center', rotation='vertical')
fig.tight_layout(pad=0.2)
plt.show()
fig.savefig(figure_path+'Reference_Climate_Comparison_of_Mappables.pdf',bbox_inches='tight')
I am able to almost do this successfully, except the original guess I made for the x displacement of my colorbars on the left side of the figure was too large:
To fix this I simply adjusted the first index of each subplot's "Cbar_ax" variable to be slightly smaller (e.g. from 0.3 to 0.25):
Cbar_ax3 = fig.add_axes([0.25,0.58,0.01,0.10])
The adjustment works for some subplots, but for others the colorbars all but vanish:
I have no idea how to solve this problem. I can make the colorbars appear using plt.colorbar() instead of fig.colorbar() without an colorbar axes designation, but the subplots themselves are not a consistent size with the rest of the figure (since plt.colorbar steals axes space from it's parent axes by default). What am I not seeing here? Why do some of these colorbars disappear when I move them?
What is the best way to specify my colorbar legend location while ensuring the legend title is within the figure? Sometimes the location will be upper right, as shown here; but in other plots it will be variable, upper/lower left/right.
It is okay if the solution doesn't use inset_axes().
Alternative Solution:
It would also be okay if the colorbar legend is to the right of the subplot, if the "My Legend" title is vertical and on the left, and the tick labels are on the right and horizontal (I don't know how to do that).
Using Python 3.8.
## Second Plot
vals2 = ax2.scatter(df.x, df.y, edgecolors = 'none', c = df.z,
norm = mcolors.LogNorm(), cmap=rainbow)
ax2.set_aspect('equal')
ax2.set_title('Subplot Title', style='italic');
ax2.set_xlabel('x');
ax2.set_ylabel('y');
cbaxes = inset_axes(ax2, width="30%", height="10%", location = 'upper right')
clb = plt.colorbar(vals2, cax=cbaxes, format = '%1.2f', orientation='horizontal');
clb.ax.set_title('My Legend')
I would still prefer to have the colorbar (with tick labels and title) inside the subplot; but I did find a way to do the Alternative Solution:
vals2 = ax2.scatter(df.x, df.y, edgecolors = 'none', c = df.z,
norm = mcolors.LogNorm(), cmap=rainbow)
ax2.set_aspect('equal')
ax2.set_title('Subplot Title', style='italic');
ax2.set_xlabel('x');
ax2.set_ylabel('y');
clb = fig.colorbar(slips2, ax=ax2, format = '%1.2g', location='right', aspect=25)
clb.ax.set_ylabel('My Legend')
clb.ax.yaxis.set_label_position('left')
The color bar is taller than the subplot because ax2 is constrained to be equal xy aspect ratio based on the limits in another subplot (ax1, not shown).
I am trying to make several pie charts that I can then transition between in a presentation. For this, it would be very useful for the automatic layouting to... get out of the way. The problem is that whenever I change a label, the whole plot moves around on the canvas so that it fits perfectly. I'd like the plot to stay centered, so it occupies the same area every time. I have tried adding center=(0,0) to ax.pie(), but to no avail.
Two examples:
Image smaller, left
Image larger, right
Instead of that effect, I'd like the pie chart to be in the middle of the canvas and have the same size in both cases (and I'd then manually make sure that the labels are on canvas by setting large margins).
The code I use to generate these two images is:
import matplotlib.pyplot as plt
import numpy as np
# Draw labels, from
# https://matplotlib.org/3.2.2/gallery/pie_and_polar_charts/pie_and_donut_labels.html#sphx-glr-gallery-pie-and-polar-charts-pie-and-donut-labels-py
def make_labels(ax, wedges, labs):
bbox_props = dict(boxstyle="square,pad=0.3", fc="w", ec="k", lw=0.72)
kw = dict(arrowprops=dict(arrowstyle="-"),
bbox=bbox_props,
zorder=0, va="center")
for i, p in enumerate(wedges):
if p.theta2-p.theta1 < 5:
continue
ang = (p.theta2 - p.theta1) / 2. + p.theta1
y = np.sin(np.deg2rad(ang))
x = np.cos(np.deg2rad(ang))
horizontalalignment = {-1: "right", 1: "left"}[int(np.sign(x))]
connectionstyle = "angle,angleA=0,angleB={}".format(ang)
kw["arrowprops"].update({"connectionstyle": connectionstyle})
ax.annotate(labs[i], xy=(x, y),
xytext=(1.1*x,1.1*y),
horizontalalignment=horizontalalignment, **kw)
kw=dict(autoscale_on=False, in_layout=False, xmargin=1, ymargin=1)
fig, ax = plt.subplots(figsize=(3, 3), dpi=100, subplot_kw=kw)
wedges, texts = ax.pie(x=[1,2,3], radius=1,
wedgeprops=dict(width=1),
pctdistance=0.7,
startangle=90,
textprops=dict(fontsize=8),
center=(0, 0))
make_labels(ax, wedges, ["long text", "b", "c"])
#make_labels(ax, wedges, ["a", "b", "long text"])
plt.show()
Thanks a lot in advance!
How are you saving your figures? It looks like you may be using savefig(..., bbox_inches='tight') which automatically resized the figure to include all the artists.
If I run your code with fig.savefig(..., bbox_inches=None), I get the following output
How to properly give Annotations to Pandas Bar Charts?
I'm following Bar Chart Annotations with Pandas and MPL, but somehow I can't make it into my own code -- this is as far as I can go. What's wrong?
I've also found the following code from here:
def autolabel(rects):
# attach some text labels
for rect in rects:
height = rect.get_height()
ax.text(rect.get_x() + rect.get_width()/2., 1.05*height,
'%d' % int(height),
ha='center', va='bottom')
autolabel(rects1)
autolabel(rects2)
But I don't how to apply that to my code either. Please help.
UPDATE:
Thank you #CT Zhu, for the answer. However, in your horizontal bars, you are still placing the text on top of bars, but I need the text show up within or along them, like this from my referenced article,
where s/he says,
"I am very parital to horizontal bar charts, as I really think they are easier to read, however, I understand that a lot of people would rather see this chart implemented in a regular bar chart. So, here is the code to do that; you will notice that a few things have changed in order to create the annotation"*
It appears your autolabel function is expecting a list of patches, sssuming your plot only those bars as its patches, we could do:
df = pd.DataFrame({'score':np.random.randn(6),
'person':[x*3 for x in list('ABCDEF')]})
def autolabel(rects):
x_pos = [rect.get_x() + rect.get_width()/2. for rect in rects]
y_pos = [rect.get_y() + 1.05*rect.get_height() for rect in rects]
#if height constant: hbars, vbars otherwise
if (np.diff([plt.getp(item, 'width') for item in rects])==0).all():
scores = [plt.getp(item, 'height') for item in rects]
else:
scores = [plt.getp(item, 'width') for item in rects]
# attach some text labels
for rect, x, y, s in zip(rects, x_pos, y_pos, scores):
ax.text(x,
y,
'%s'%s,
ha='center', va='bottom')
ax = df.set_index(['person']).plot(kind='barh', figsize=(10,7),
color=['dodgerblue', 'slategray'], fontsize=13)
ax.set_alpha(0.8)
ax.set_title("BarH")#,fontsize=18)
autolabel(ax.patches)
ax = df.set_index(['person']).plot(kind='bar', figsize=(10,7),
color=['dodgerblue', 'slategray'], fontsize=13)
ax.set_alpha(0.8)
ax.set_title("Bar")#,fontsize=18)
autolabel(ax.patches)
I have found minor graphical issues while using the spanselector, cursor and fill_between widgets, which I would like to share with you.
All of them, can be experienced in this code (which I took from the matplolib example)
"""
The SpanSelector is a mouse widget to select a xmin/xmax range and plot the
detail view of the selected region in the lower axes
"""
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import SpanSelector
import matplotlib.widgets as widgets
Fig = plt.figure(figsize=(8,6))
Fig.set_facecolor('w')
Fig.set
Ax = Fig.add_subplot(211)
x = np.arange(0.0, 5.0, 0.01)
y = np.sin(2*np.pi*x) + 0.5*np.random.randn(len(x))
Ax.plot(x, y, '-')
Ax.set_ylim(-2,2)
Ax.set_title('Press left mouse button and drag to test')
RegionIndices = []
ax2 = Fig.add_subplot(212)
line2, = ax2.plot(x, y, '-')
def onselect(xmin, xmax):
if len(RegionIndices) == 2:
Ax.fill_between(x[:], 0.0, y[:],facecolor='White',alpha=1)
del RegionIndices[:]
indmin, indmax = np.searchsorted(x, (xmin, xmax))
indmax = min(len(x)-1, indmax)
Ax.fill_between(x[indmin:indmax], 0.0, y[indmin:indmax],facecolor='Blue',alpha=0.30)
thisx = x[indmin:indmax]
thisy = y[indmin:indmax]
line2.set_data(thisx, thisy)
ax2.set_xlim(thisx[0], thisx[-1])
ax2.set_ylim(thisy.min(), thisy.max())
Fig.canvas.draw()
RegionIndices.append(xmin)
RegionIndices.append(xmax)
# set useblit True on gtkagg for enhanced performance
span = SpanSelector(Ax, onselect, 'horizontal', useblit = True,rectprops=dict(alpha=0.5, facecolor='purple') )
cursor = widgets.Cursor(Ax, color="red", linewidth = 1, useblit = True)
plt.show()
I wonder if there is some way to avoid these two small issues:
1) You can see that when you select a region the spanselector box (purple) glitches. In this code the effect is barely noticeable but on plots with many lines is quite annoying (I have tried all the trueblit combinations to not effect)
2) In this code when you select a region, the area in the upper plot between the line and the horizontal axis is filled in blue. When you select a new region the old area is filled in white (to clear it) and the new one is filled with blue again. However, when I do that the line plotted, as well as, the horizontal axis, become thicker... Is there a way to clear such a region (generated with fill_between) without this happening... Or is it necessary to replot the graph? Initially, I am against doing this since I have a well structured code and importing all the data again into the spanselector method seems a bit messy... Which is the right way in python to delete selected regions of a plot?
Any advice would be most welcome
