Version Upgrade for Raspbian (not an issue; request for advice only)

[baqwas]

Hello @DanielGoldfarb,

I'm running mplfinance on Raspberry Pi Zero under Raspbian Buster because I have easy access to this hardware that I have dedicated for unattended operations 24x7 ):

`$ cat /proc/cpuinfo
processor : 0
model name : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS : 697.95
Features : half thumb fastmult vfp edsp java tls
CPU implementer : 0x41

CPU variant : 0x0
CPU part : 0xb76
CPU revision : 7

Hardware : BCM2835
Revision : 9000c1

Model : Raspberry Pi Zero W Rev 1.1
pi@raspbari3:~ $ uname -a
Linux raspbari3 4.19.97+ #1294 Thu Jan 30 13:10:54 GMT 2020 armv6l GNU/Linux
$
I installed **mplfinance** using standard _pip_ operation as follows (sudo is superfluous but old habits die hard):sudo python3 -m pip install mplfinance`

The process installed mplfinance v0.11

Please add a paragraph or two in your installation section of the documentation on how to upgrade using the github repository. As you can understand I am a novice at these things and running ./setup.py did not work out at all for me. I am not planning to use Jupyter/IPython/Cython/etc. I will simply use cron to plot daily (with data from alphavantage) in batch mode and post the saved plots for review. If you feel that this is not the best way to use mplfinance, please do let me know and I will adjust according to your suggestions. Thanks again.

Kind regards.

Please try

pip install --upgrade mplfinance

Let me know if that works for you. You should get version 0.12.3a3

Regarding:

That's a good idea. I will try to include some documentation along those lines in the near future.

Also, I see no problem using cron to run a batch Python script that calls mplfinance to generate a plot and save it to a file. That should work fine (assuming data is available at the time the job runs, etc.) I would just recommend that you log some details of what you are doing in the script, both before and after the plot. That way, if something goes wrong (since you may not be around when it runs) the log will help you track down what went wrong.

If you want to install the version GitHub that has not yet been released to PyPi, there are a couple ways to do that. If you already have the repository locally, you can do git pull to update the repository to the latest version. Alternatively you can just delete what you have and then again git clone the repository from GitHub.

Once you have the repository on your local machine, cd into the main mplfinance directory (the one that contains setup.py) and then run the following command:

pip install . <enter>

notice the dot '.' after pip install

---

If you ever want to experiment with making changes to the mplfinance code, locally on your machine, you can do the same as the above, but then run:

pip install --editable . <enter>

The --ediatable flag will make it so that your installed version will point to your local repository. This means that any changes you make will automatically be reflected in the installed version.

Note: The fact that you are using version v0.11 also explains this issue as there were certain conditions where the x-axis labels display would get clipped; That bug was fixed in a later version. Please pick up v0.12.3a3 from Pypi (pip install --upgrade mplfinance).

Also, note that v0.12.4a0 will be released in approximately one week (but is partially available now on GitHub). See #67 for more information.

Hello @DanielGoldfarb,

You are correct once again! Having realized that --upgrade didn't work for me, in my naive ignorance, I ran setup.py directly not via pip. After reading your instructions, I ran it through pip as you suggested and now I am exactly where I would like to be with the tutorials. Many, many thanks for your help. Just for the record (in case it helps others, I have posted below the differences in my two approaches).

Kind regards.
