I am building my project in React.js where I have added several graphs and I want to download the Graph data in PDF format on click of a button. With graph data I would also want to have graph images, but this is my secondary requirement.
Can anyone help me with this.
Thank you in advance.
There are a couple of ways that you could approach this, the easier way I think is you could do it on the client side using a library such as html2pdf. The other way is you could do it on the backend using a server side library. I recently did something similar and I ended up doing it on the client side using this library https://ekoopmans.github.io/html2pdf.js/ and it was pretty easy to implement.

I'm a newbie to codenameone. I'm trying to develop some image-processing app. I need to know if the image has geotagging information and eventually extract those. Is there a way to do that in CodenameOne?
I'm aware of the methods based on plain javax.imageio packages, but I know that those are not available in codenameone.
Thanks for any hints!
We don't have such an API as it's pretty different between Android/iOS. You can write something like this in pure Java and parse the image header which should be relatively simple.
Or you can build a cn1lib on top of native code e.g. see this library, It does that for video which is arguably harder.
I have an orientdb instance running and can access everything in Studio without any problem. My goal is to have a react webpage that has just the interactive graph embedded in it. Basically, I want to be able to look at the graph just like I would in Studio, but on my webpage. I know I could do this by doing a query and then creating an interactive graph through something like plotly, but I would rather just get the graph directly from the orientdb server. Is there support for this? I've been combing through the orientdb docs and have not found anything like this functionality, but I feel like it would be an obvious thing to have.
Thanks in advance!
AFAIK there's nothing like that. OrientDB provides the REST api, then it's up to you build your interactive user interface embedded in your own application.
There is also ArcadeAnalytics https://github.com/ArcadeAnalytics/arcadeanalytics
It is a data visualization tool that works with OrientDB and other graph databases.
The frontend uses https://github.com/cytoscape/cytoscape.js to render the graph.
So, at least, you can take inspiration or extract the parts you need.
I think that building a springboot application that uses the Orientdb connector (https://github.com/arcadeAnalytics/arcade-connectors/) should be easy.
In short, I'm building web application with React which will need to support Microsoft OneNote. But as far as I've searched, there is no embeding for OneNote?
So my question is. How to implement as much functionality as possible using OneNote Graph Api and React? What I thought so far is using react-rte... but that package supports only one editing box ( one note page consists of multiple editable parts which each has it's own position, cordinates, etc.. so thats doesn't seem to be a solution..) Maybe i missed any other good libraries or there aren't any?
Embedding OneNote in your web application is currently not supported.
If you believe we should have this functionality, I encourage you to upvote this item in uservoice: https://onenote.uservoice.com/forums/245490-onenote-developer-apis/suggestions/5909975-allow-live-onenote-pages-to-be-embedded-on-a-websi
I'm looking to create a website around a tool that plugs info from different sites into a form on mine. I'd like to eliminate/streamline data-entry. Anyone know a good way to accomplish this?
There are plenty of web scraper scripts available on github that can do data capture from web.
You will still need programming skills to change and plug those scripts as per your requirement. Here is one such parser but you must know basic DOM and programming to access information of your need from a website.
Apart from this you can also use excel sheet to access web data and then you can fill your form with that data.
You should try to learn web scraping using python. Threre are plenty of web based tutorials for it. Youtube may also be helpful.
What I need is a method to display a graph of data from a tab delimited file uploaded to a website. Once the file is uploaded the program will convert the data to a graph or the graph be generated locally and sent to website, but it needs to be automated and in realtime.
Thanks,
Antone
Your question is rather broad.
The answers to these questions usually depend upon what sort of programming framework you will be using for your website. For example, PHP has some native libraries to generate graphs based on submitted data in multiple formats. But that may not be what you are looking for and using something like dojo or ExtJS might be better. Or if you are a Java/JSP person, then there are lots of frameworks that can handle this. Of course .NET might be better. I am sure the Python and Ruby folks have their own thoughts as well and then of course there is Delphi.
