In first place when I used just df_resample_by_month.plot, the x_compat=True solved initial problem and fixed the dates that even though the range in column Date is 01/01/2015 - 31/12/2022 xaxis is shown arbitrarily from 01-1970 to 04-1970 after using DateFormatter, but when I add plot.bar then below error came up
ax=df_resample_by_month.plot.bar(figsize=(35,4),x='Date', y=['Sales(value)'],color='#CD5C5C',x_compat=True)
ax.autoscale(axis='x',tight=True)
ax.xaxis.set_major_locator(dates.MonthLocator(bymonth=None,interval=1))
ax.xaxis.set_major_formatter(dates.DateFormatter('%m-%Y'))
ax.xaxis.set_tick_params(rotation=90)
ax.yaxis.set_major_formatter(ticker.EngFormatter())
AttributeError: 'Rectangle' object has no property 'x_compat
Is there any way to have x_compat=True to the bar chart also to fix the problem with dates that shows year 1970?

I am using PyQt based on Qt4. My Editor is PyCharm 2017.3 and my python version is 3.4. I am scraping some text from a website. I am trying to align that text to the center of the cell in a QTableWidget.
item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)
self.tableWidget.setItem(x, 2,item)
Therefore while putting the item in the cell, I am trying to align it as per the documentation. The problem is that the data is not showing up.
It did show up when I removed setTextAlignment method as shown below
item = QTableWidgetItem(scraped_age)
self.tableWidget.setItem(x, 2,item)
This line of code:
item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)
will not work properly, because it throws away the item it creates before assigning it to the variable. The variable will in fact be set to None, which is the return value of setTextAlignment(). Instead, you must do this:
item = QTableWidgetItem(scraped_age) # create the item
item.setTextAlignment(Qt.AlignHCenter) # change the alignment
This didn't work for me, and I'm not sure if it is because I'm using PyQt5 or it i did something wrong. I was trying to find something similar but for the whole table, and i finally stumbled upon something that worked and lets you center every cells or just one column at a time.
You have to use the delegate method:
#You're probably importing QtWidgets to work with the table
#but you'll also need QtCore for the delegate class
from PyQt5 import QtCore, QtWidgets
class AlignDelegate(QtWidgets.QStyledItemDelegate):
def initStyleOption(self, option, index):
super(AlignDelegate, self).initStyleOption(option, index)
option.displayAlignment = QtCore.Qt.AlignCenter
After implementing this in your code, you can add the following to your main window class or wherever the table is defined:
delegate = AlignDelegate(self.tableWidget)
self.tableWidget.setItemDelegateForColumn(2, delegate) #You can repeat this line or
#use a simple iteration / loop
#to align multiple columns
#If you want to do it for all columns:
#self.tableWidget.setItemDelegate(delegate)
Know this is an old question, but hope it can help someone else.
Bit late to the party but for those of you wondering how to do this on pyqt5
table = QTableWidgetItem() #QTWidgets.QTableWidgetItem() if importing QWidget from PyQt5
table.setTextAlignment(number)
setTextAlignment takes an int for the argument (alignment). Put the number in to get the result:
0:left
1:left
2:right
3:right
4:centre
I have code that plot tabular data I have . The code choose everytime different row (observation) to plot and display the data and the legend with the name of the observations.
My problem is that that even if I change the displayed data using the iloc (e.g changing the rows to be displayed) , I still get the same legend .
for example:
If I use this code, that suppose to display rows 0-10:
SavitzkyGolay(db_plants.iloc[:10,5:],25,2).T.plot(title='25/06/2019 17:00',figsize=(17,10))
plt.legend(db_plants['plant'])
The result I get is this :
But when I change the iloc:
SavitzkyGolay(db_plants.iloc[12:22,5:],25,2).T.plot(title='25/06/2019 17:00',figsize=(17,10))
plt.legend(db_plants['plant'])
I get the same legend:
*I can't share the original dataframe
*The observations names are different for sure
My end goal: to have the correct observations displayed in the legend
EDIT: I have used the iloc :
SavitzkyGolay(db_plants.iloc[12:22,5:],25,2).T.plot(title='25/06/201917:00',figsize=(17,10))
plt.legend(db_plants['plant'].iloc[12:22,5:])
But I still gett error:
IndexingError: Too many indexers
I'm setting the value of a bootstrap datepicker by making use of the setValue method provided.
For example
tripToDatePicker.setValue(tripFromDatePicker.date);
But for some reason the calendar is not updated
'setValue' is replaced by 'setDate'.
Using a string as input for setDate can be tricky. It has to match with the dateformat, else you can get unexpected results. It is more safe to create a 'new Date(y,m,d)' from your input, e.g. new Date(2015,3,10) for '10 Apr 2015'. This will always work.
When using a date representation in seconds, e.g. 1428659901, then use 'new Date(value*1000)'. Note that datepicker will eat any value here, but only show the selected date in the calendar if hours, minutes and seconds are equal to 0. Took me a while to figure that out....
Edit:
http://www.eyecon.ro/bootstrap-datepicker/ is not much documented, you should try http://eternicode.github.io/bootstrap-datepicker/.
anyway the code below will work for you
$("#dp1").datepicker("update", "02-16-2012");
or
$("#dp1").datepicker("setValue", "02-17-2012");
where "#dpi" is the id of the text field on whcih datepicker is used.
After trying many things, I ended up using "update" method. The $("#dp1").datepicker("update", "02-02-2012") or $("#dp1").datepicker("update", "02/02/2012") works for me. Surprisingly no document about this method at author website. Thanks.
I have this interactive chart here. As its data change depending on selected time period I wish to set the date range from Nov-10 to Jul-14, no matter the data. I know that I must use overrideMax on x axis, but I can't make it to work. I guess it's a matter of date formatting. Every single combination I've tried gives the following as result.
What is the right formatting? Thanks a lot.
EDIT: Thank you very much on your quick response, John. Now it is working. I'm loving Dimple more and more!
I have another question regarding this chart. Is there any way to arrange drawing order of series? I would like 'Previsión' to be sent to back. Now it is drawn depending on time period.
EDIT 2: Based on this other question I think I figured out a solution. With a 50ms delay after the chart is drawn I simple erase the circles and paths I wish to be at the front and then append them to the chart svg object.
setTimeout(function () {
var datoCircles = svg.selectAll('circle[id*=Dato]:not([id*=futuro])');
var prevCircles = svg.selectAll('circle[id*=Prev]');
var prevPaths = svg.selectAll('path[class*=Prev]');
datoCircles.remove();
prevCircles.remove();
prevPaths.remove();
// Convertimos la seleción d3 a objetos jQuery
$(svg.selectAll('svg > g')[0])
.append($(prevPaths[0]))
.append($(prevCircles[0]))
.append($(datoCircles[0]));
}, 50);
They need to be set with JavaScript date objects, as native date parsing in JavaScript causes cross browser problems, I recommend using the d3 method:
x.overrideMax = d3.time.format("%Y-%m-%d").parse("2014-05-09");
With this approach you can use whichever date format suits you.
Having trouble spider charting with only one series.
I tried working off this example:
http://archive.dojotoolkit.org/nightly/dojotoolkit/dojox/charting/tests/test_spidersingle.html
And set that up here:
http://jsfiddle.net/mstefanko/FHnwd/72/
Firebug is throwing:
Unexpected value NaN parsing cy attribute.
I'm completely new to the dojo toolkit. I know I need to addAxis, but it doesn't look like the code from the top URL is working. The axis is starting and ending at the same number despite my trying to set min/max.
Any help is appreciated!
Problem has to do with spider charts figuring out the min/max of the axis on it's own. Even when I was using:
chart1.addAxis("Answer 3", { type: "Base", min: 0, max: 250 });
to set the min and max, the spider chart still bombed with only one series.
After playing around with the information in this ticket:
http://bugs.dojotoolkit.org/ticket/14583
I still wasn't able to get this working, I stumbled onto an answer here that basically said as a workaround add series for min and max then remove them after render. So thats exactly what I ended up doing.
chart.render();
chart.removeSeries("min");
chart.removeSeries("max");
Demonstrated here:
