MvvmCross vnext - Initialising IMvxGeoLocationWatcher problems - xamarin.ios
Continuing the journey into vnext...
I can now build the entire solution & run it successfully. However, when I try to initialise the IMvxGeoLocationWatcher, it crashes. The code & output are -
private IMvxGeoLocationWatcher _geoWatcher;
public void StartGettingLocation(Action<MvxCoordinates> response)
{
Log.Info("LocationService->StartGettingLocation");
// crashes on this line -
if (_geoWatcher == null) _geoWatcher = this.GetService<IMvxGeoLocationWatcher>();
Output -

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
Thanks for any help.
Without the inner exception it's hard to know what has gone wrong - sorry.
I'd guess that there is some problem in initializing the geowatcher - either because:
the plugin isn't registered
you call this line before you've called Cirrious.MvvmCross.Plugins.Location.PluginLoader.Instance.EnsureLoaded()
or because of some 'app specific reason'.
The tutorial app uses the location plugin in: https://github.com/slodge/MvvmCross/tree/vnext/Sample%20-%20Tutorial/Tutorial/Tutorial.UI.Touch
Does the tutorial work for you? If it does, then you'll maybe need to look at comparing the two.
If the crash persists for you, then maybe:
- post the inner exception if you can?
- or post a small repo which demos the problem - I'd certainly need more code than I can see in this 2 line snippet.
Sorry for the lack of documentation. I am making a huge effort right now to create proper documents and tutorials for the new v3 released - but this is all self-funded!

Problem is related to a matplotlib regression in 3.3.1. Original seaborn issue (closed) Solution is to pin matplotlib to 3.3.0 until 3.3.2 is released, although the next release of seaborn will include a workaround. Update (9/10/20): Seaborn 0.11.0 is now available that contains the workaround to make scatterplots work even with matplotlib 3.3.1.
I've noticed the same error mentioned originally by #Hitsesh Somani is occurring even for some of the example code snippets given on Seaborn's official site (https://seaborn.pydata.org/generated/seaborn.scatterplot.html).
For example the below example, copied and pasted directly from Seaborn, gives the same error as mentioned by #Hitesh Somani:
import seaborn as sns; sns.set()
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")
ax = sns.scatterplot(x="total_bill", y="tip", hue="time", data=tips)
the above will return the following error:

matplotlib plot negative num in diffrent color
I want use red and green to distinguish positive and negative num which will be used abs(num) in one picture. I search on web and find some method to deal with it. but the result is error. I paste the code and wish sb. to help.

why this happen?
and what i really what to do is make a bar chart of cumsum size and plot price in the same image
or
if size>n(linspace maybe 50,100,200),make the whole background which in several time range in different colors. like between 2017-8-19 08:20:10 and 2017-8-19 08:30:20,size=70,then use yellow to fill this range background.and between 2017-8-20 08:20:10 and 2017-8-20 08:30:20,size=150,then use red to fill this range background.
just solve one problem is good, some idea can not figure out in one time:)
Issue plotting Seaborn and Matplotlib figures using loop
I am having some trouble saving a series of two Seaborn violin plots and a normal matplotlib plot which runs each time my code iterates over a loop.
My code is:
for symbol in symbol_list:
<DO SOMETHING - CREATE PANDAS DATAFRAME NAMED "df">
img = sns.violinplot(x=df['Onside'].dropna().astype(float))
fig = img.get_figure()
fig.savefig(symbol+" Onside Violin Plot.png")
fig.clf()
sns.violinplot(x=df['Offside'].dropna().astype(float))
fig = img.get_figure()
fig.savefig(symbol+" Offside Violin Plot.png")
fig.clf()
plt.figure(1)
plt.subplot(211)
plt.hist(df['Onside'],bins=50,alpha=0.5,label="Onside")
plt.hist(df['Offside'],bins=50,alpha=0.5,label="Offside")
plt.legend(loc='best')
plt.xlabel("Pips")
plt.ylabel("Number of Trades")
plt.subplot(212)
plt.bar(df.index,df['Offside'],color='r',width=0.5)
plt.bar(df.index,df['Onside'],color='blue',width=0.5)
plt.savefig(symbol+'_Onside_Offside')
plt.plot()
It runs correctly on the first iteration through the loop but on the second go around I get the following error message:
---------------------------------------------------------------------------

ValueError: ordinal must be >= 1
Could anyone please point out where I am going wrong?
I assume it's seomthing to do with the "plt" figure not being cleared properly and therefore the code is trying to plot two different indices on the x axis of the same figure, hence the "ordinal must be >= 1" error.
Am i in the right ball park?
You need to clear the figure first thing in the loop, otherwise the new content would be plottet to the old figure from the previous loop step. So you can add plt.gcf().clf() at the start of the loop.
