I have downloaded the last version I found (18/04/2017) of hist_stock_data.
It does not get the data from Yahoo (returning zero status).
Any way to fix this?
Any alternative for downloading stock data from Matlab?
Have you tried to use the fetch function?
d = fetch(c,s) returns data for all fields from the Yahoo! website for the indicated security.
Note: This function does not support retrieving multiple securities at once. You must fetch a single security at a time.

I have a column of hundreds of parcel tracking numbers, and I want to use the parcel carrier's REST API to pull some of the tracking information (promised delivery date, and actual delivery date) and then use conventional spreadsheet techniques on it.
Is there a simple way to put the REST call in a formula in an excel cell? in pseudocode it would be call this REST url, using the tracking number in the cell to the left as an argument, and here's the authentication user/password, and return the value in the response field 'deliveryDate'
I am intrigued by Power Query and I figured out how to use Power Query to do it for a static REST url with the tracking number manually filled in, but I don't know how to make PQ do it for hundreds of items.
or maybe there is an online tool for building this function with lego blocks for a caveman like myself?
I have this weird issue when I try to get data from Identity protection by using MS graphs API, I only get two months ago data and not recent ones, what could be the issue here?
I'm using PowerShell to extract the data
Okay, I figure out the mistake I'm doing in here, https://graph.microsoft.com/v1.0/identityProtection/riskDetections is not only a single output
once I add a while loop until '#Odata.NextLink' is not null it gives me the full range
I'm pretty confused concerning this hip thing called NoSQL, especially CloudantDB by Bluemix. As you know, this DB doesn't store the values chronologically. It's the programmer's task to sort the entries in case he wants the data to.. well.. be sorted.
What I try to achive is to simply get the last let's say 100 values a sensor has sent to Watson IoT (which saves everything in the connected CloudantDB) in an ORDERED way. In the end it would be nice to show them in a D3.css style kind of graph but that's another task. I first need the values in an ordered array.
What I tried so far: I used curl to get the data via PHP from https://averylongID-bluemix.cloudant.com/iotp_orgID_iotdb_2018-01-25/_all_docs?limit=20&include_docs=true';
What I get is an unsorted array of 20 row entries with random timestamps. The last 20 entries in the DB. But not in terms of timestamps.
My question is now: Do you know of a way to get the "last" 20 entries? Sorted by timestamp? I did a POST request with a JSON string where I wanted the data to be sorted by the timestamp, but that doesn't work, maybe because of the ISO timestamp string.
Do I really have to write a javascript or PHP script to get ALL the database entries and then look for the 20 or 100 last entries by parsing the timestamp, sorting the array again and then get the (now really) last entries? I can't believe that.
Many thanks in advance!
I finally found out how to get the data in a nice ordered way. The key is to use the _design api together with the _view api.
So a curl request with the following URL / attributes and a query string did the job:
https://alphanumerical_something-bluemix.cloudant.com/iotp_orgID_iotdb_2018-01-25/_design/iotp/_view/by-date?limit=120&q=name:%27timestamp%27
The curl result gets me the first (in terms of time) 120 entries. I just have to find out how to get the last entries, but that's already a pretty good result. I can now pass the data on to a nice JS chart and display it.
One option may be to include the timestamp as part of the ID. The _all_docs query returns documents in order by id.
If that approach does not work for you, you could look at creating a secondary index based on the timestamp field. One type of index is Cloudant Query:
https://console.bluemix.net/docs/services/Cloudant/api/cloudant_query.html#query
Cloudant query allows you to specify a sort argument:
https://console.bluemix.net/docs/services/Cloudant/api/cloudant_query.html#sort-syntax
Another approach that may be useful for you is the _changes api:
https://console.bluemix.net/docs/services/Cloudant/api/database.html#get-changes
The changes API allows you to receive a continuous feed of changes in your database. You could feed these changes into a D3 chart for example.
Explanation:
I am able to query the Google Core reporting APIv3 using the client library to get data on pageviews for specific URLs of a website I am working on. I want to get data(pageviews) for each day within a specified range. So far I am simply looping through the range, sending individual request to the API. in each request I am setting the same value for the start date and the end date.
Problem:
Obviously this gets the job done, BUT it is certainly not the best way to go about it. Because, assumming I want to get data for the past 3 months for each of about 2000 URIs. Then I will need 360000 number of requests and that value is well over the limit quota defined by Google.
Potential solution: So one way I thought of solving this issue is probably to send a request setting start-date and end-date to be a week apart but the API will return a sum of the values rather than the individual values.
main question: So is there a way to insist that these values should not be added up and returned as a sum but rather returned (as associative array or something like that) separately for each.
I hope the question is clear and that there is a solution! Thank you!
Very straightforward:
Metric: ga:pageview, Dimension: ga:date, Set a filter for your pagepath, and set a start-date and end-date.
Example:
https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3Axxyyzz&dimensions=ga%3Adate&metrics=ga%3Apageviews&filters=ga%3Apagepath%3D%3D%2Ffaq.html&start-date=2013-06-27&end-date=2013-07-11&max-results=50
This will return the pageviews for that the faq.html& page for each day in the time-frame.
You should check out the QueryExplorer. Great tool to find out how to structure queries.
Right now I am working on a project to fetch data from a SharePoint list using SOAP API. I tried and successfully fetches the complete list, but now I want to fetch some specific data that is updated after a specific date.
Is this possible to fetch such data using SOAP query. I can see last update filed when I view single item at the bottom. Is this some how possible to use that filed?
Yes you can use the Web Services to do lot of things just like filtering a list result. I don't know which language you use, but with JavaScript you can look at these two frameworks that should help you:
http://aymkdn.github.io/SharepointPlus/ : easy way to create your queries (I created it)
http://spservices.codeplex.com/ : the most popular framework but less easy to use (it's my point of view)
You can also look at the documentation on MSDN (the param to use is query): http://msdn.microsoft.com/en-us/library/lists.lists.getlistitems.aspx
At last found the answer,
The last update date and time can be retrieved from the list column "Modified".
The soap response will have the value in the attribute "ows_Modified".
