I am trying to import a matplotlib to html with xkcd theme. My code is as follows (no data,just a fig)
fig = plt.figure(facecolor = '#eee8d5')
#plt.matplotlib.rcdefaults()
with plt.xkcd():
ax = fig.add_subplot(111)
ax.set_axis_bgcolor('#eee8d5') #set_color('#fdf6e3')
ax.title.set_color('#d33682') # Magenta
ax.tick_params(axis='x', colors='#657b83')
ax.tick_params(axis='y', colors='#657b83')
ax.spines['bottom'].set_color('#657b83')
ax.spines['left'].set_color('#657b83')
ax.spines['right'].set_color('none')
ax.spines['top'].set_color('none')
ax.set_title('Title', fontsize = 18);
html = mpld3.fig_to_html(fig)
Html_file= open("CumPrctWordFrq.html","w")
Html_file.write(html)
Html_file.close()
So far so good -- everything renders correctly in the python notebook. However when I paste the html on a website (squarespace), the fig loses all the xkcd properties. Eventually I would like to make this interactive. The idea is eventually to produce a xkcd -> solarized -> interactive plot.
mpld3 does not yet support the plt.xkcd() mode. If this is something you want, you should creat an issue in the mpld3 issue tracker, and see if someone is inspired to work on it.

I have Matlab 2019b, GUI Layout Toolbox 2.3.4 and t all runs on MacOs 14 Mojave.
I want to create button in in a UI that have icons/images instead of text. I have seen here:
https://undocumentedmatlab.com/blog/html-support-in-matlab-uicomponents/
that it is supposed to be possible to use HTML to render the button contents.
So - I try this sample code:
figure('MenuBar','none','Name','GUI-TEST','NumberTitle','off','Position',[200,200,140,90]);
push_btn = uicontrol('Style','PushButton','String','Push','Position',[30,60,80,20],...
'CallBack','disp(''You are pressed a push button'')');
close_btn = uicontrol('Style','PushButton','String','Close','Position',[30,5,80,50],...
'CallBack','close');
icon_file = fullfile(pwd, 'close.png')
str = ['<html><img src="file://' icon_file '"></html>']
set(close_btn,'String',str);
but it leaves me with an empty button.
If I deliberately use a filename that does not correspond to an existing file, I see a broken image icon:
So I am reasonably sure that the basic syntax and file path stuff is correct but the image does not get rendered in the button.
Is there something else I need to do to make this work or is it all just part of Matlab's overwhelming strangeness?
The easiest way to put an image on a uicontrol (and specifically a button), is to use the CData property,
im_orig = imread(icon_file); % Needs to be true color, i.e. MxNx3
im_sized = imresize(im_orig,[80,50]); % size of the button
% str = ['<html><img src="file://' icon_file '"></html>'];
% set(close_btn,'String',str);
set(close_btn,'CData',im_sized);
I have seen great examples of how bokeh allows you to hover over a data point and display pop up details for it. There are cases the details is so overwhelming voluminous, it really requires a side panel to display it all. Is bokeh a complete enough widget toolkit where I can create a side panel to the main display and show details of a data point following the cursor?
Can someone point out some sample code, or at least the relevant api's.
If you prefer a higher-level API for building and linking Bokeh-based plots, you can use HoloViews; see linking examples at http://holoviews.org/reference/index.html#streams and instructions at http://holoviews.org/user_guide/Custom_Interactivity.html . For example:
import param, numpy as np, holoviews as hv
from holoviews import opts, streams
hv.extension('bokeh')
xvals = np.linspace(0,4,202)
ys,xs = np.meshgrid(xvals, -xvals[::-1])
img = hv.Image(np.sin(((ys)**3)*xs))
pointer = streams.PointerXY(x=0,y=0, source=img)
dmap = hv.DynamicMap(lambda x, y: hv.Points([(x, y)]), streams=[pointer])
dmap = dmap.redim.range(x=(-0.5,0.5), y=(-0.5,0.5))
img + dmap.opts(size=10)
You can find many examples on https://docs.bokeh.org . What you want is possible by adding a callback and updating the relevant part. In this example the div is what you name a side panel in your question.
#for bokeh 1.0.4
from bokeh.plotting import figure
from bokeh.models import ColumnDataSource,Div,Row
from bokeh.io import curdoc
from bokeh.events import Tap
#the data
d={'x':[1,2],'y':[3,4],'info':['some information on a first datapoint','some information on a second datapoint']}
source=ColumnDataSource(d)
tooltips = [("x", "$x"),("y", "$y"),("info","#info")]
fig=figure(tools="tap,reset",tooltips=tooltips)
c=fig.circle('x','y',source=source,size=15)
def callback(event):
indexActive=source.selected.indices[0]
layout.children[1]=Div(text=d['info'][indexActive])#adjust the info on the right
fig.on_event(Tap, callback)
div=Div(text=d['info'][0])
layout=Row(fig,div)
curdoc().add_root(layout)
To run this code, save it as code.py, open a cmd and type "bokeh serve code.py --show".
I am trying to display multiple dataframe in tabs using Bokeh. My code works when I save my file as html, but it fail to display inline in the Jupyter notebook.
Here is my code:
from bokeh.models.widgets import DataTable, DateFormatter,
TableColumn, Panel, Tabs
from bokeh.io import output_notebook, show
from bokeh.models import ColumnDataSource
from bokeh.plotting import figure
from bokeh.resources import INLINE
output_notebook(resources=INLINE)
source = ColumnDataSource(train.head())
columns = [TableColumn(field=col, title=col) for col in train.columns.tolist()]
data_table = DataTable(source=source, columns=columns, width=400, height=280)
tab1 = Panel(child=data_table, title="Train")
source = ColumnDataSource(prop.head())
columns = [TableColumn(field=col, title=col) for col in prop.columns.tolist()]
data_table = DataTable(source=source, columns=columns, width=len(columns)*100, height=280)
tab2 = Panel(child=data_table, title="Properties")
tabs = Tabs(tabs=[tab1, tab2])
show(tabs)
Here is the error messege:
Javascript error adding output!
Error: SlickGrid's 'enableColumnReorder = true' option requires jquery-ui.sortable module to be loaded
See your browser Javascript console for more details.
Here is my set up:
Python 3.6.1 :: Anaconda custom (64-bit)
Ubuntu 16.04 LTS
jupyter==1.0.0
jupyter-client==5.0.1
jupyter-console==5.1.0
jupyter-core==4.3.0
bokeh==0.12.7
Can someone point me a direction as what I can do to fix this?
Thanks in advance!

That looks like a SlickGrid error message. Like it says, jQueryUI.sortable is a dependency for SlickGrid.
I normally include the full build of jQueryUI in the page, along with jQuery itself, like:
<script src="../lib/jquery-1.11.2.min.js"></script>
<script src="../lib/jquery-ui-1.11.3.min.js"></script>
(or you could use the jQuery CDN).
You can also include a cut down version of jQueryUI that just includes sortable (there are known conflicts between jQueryUI and other frameworks, for example Bootstrap).
If slickgrid is part of the page, you should already have this stuff set up though.
I have no clue about Bokeh.
I have a base .docx for which I need to change the page header / footer image on a case by case basis. I read that python-docx does not yet handle headers/footers but it does handle Pictures.
What I cannot work around is how to replace them.
I found the Pictures in the documents ._package.parts objects as ImagePart, I could even try to identify the image by its partname attribute.
What I could not find in any way is how to replace the image. I tried replacing the ImagePart ._blob and ._image attributes but it makes no difference after saving.
So, what would be the "good" way to replace one Image blob with another one using python-docx? (it is the only change I need to do).
Current code is:
d = Document(docx='basefile.docx')
parts = d._package
for p in parts:
if isinstance(p, docx.parts.image.ImagePart) and p.partname.find('image1.png'):
img = p
break
img._blob = open('newfile.png', 'r').read()
d.save('newfile.docx')
Thanks,
marc
There is no requirement to use python-docx. I found another Python library for messing with docx files called "paradocx" altought it seems a bit abandoned it works for what I need.
python-docx would be preferable as the project seems more healthy so a solution based on it is still desired.
Anyway, here is the paradocx based solution:
from paradocx import Document
from paradocx.headerfooter import HeaderPart
template = 'template.docx'
newimg = open('new_file.png', 'r')
doc = Document.from_file(template)
header = doc.get_parts_by_class(HeaderPart).next()
img = header.related('http://schemas.openxmlformats.org/officeDocument/2006/relationships/image')[0]
img.data = newimg.read()
newimg.close()
doc.save('prueba.docx')
I am writing a simple plugin that changes the whole content of a Sublime editor and replaces it with something else. When doing this
viewRegion = sublime.Region(0, self.view.size())
everything = self.view.substr(viewRegion)
self.view.replace(edit, viewRegion, everything)
the view scrolls to the top. How do I prevent this or restore the original viewport?
It turns out, there isn't really a good way. You can try to get around the replace as much as possible (e.g. by using the excellent merge_utils), but this will always change the position after the command is finished.
As a hack, you can save the position and restore it in a timeout like this:
def format(self, edit):
self.curpos = self.view.viewport_position()
self.selection = self.view.sel()[0]
viewRegion = sublime.Region(0, self.view.size())
everything = self.view.substr(viewRegion)
# do something useful
self.view.replace(edit, viewRegion, everything)
# reestablish selection
sublime.set_timeout(self.reset_pos, 0)
def reset_pos(self):
self.view.sel().clear()
self.view.sel().add(self.selection)
self.view.set_viewport_position(self.curpos, False)
