I am interested in optimizing my chart pool. On my internal server; I have about 15 charts that has to go each in their own page. This means to have to change 15 times something, if I have to.
I tried to put all the common code in a single js script, so the web page has minimum code in it, but still, I need to maintain plenty of pages.
Is there a more efficient way to maintain multiple charts, that live on different pages? Ideally I would have a single page, where I use links to make new charts. I would call this function and it will generate the webpage to host the chart and the appropriate code to build the chart itself (which takes data from external files). Is JS the right tool for this job, or do I need to use something else?
I don't need anything complicate, just something that can reduce the amount of work done to maintain (and upgrade), multiple charts. Any pointer is appreciated, since I just started with webpages, CSS and such.
I would put it on a single page and use a query string parameter to decide which chart to create. I would then make the source data for the chart respect the parameter and bind correctly to the chart.
You url could be something like this: chartpage.html?chartId=1

First of all, I'm completely incompetent and my hours-long attempts at trying to make this work have been fruitless. So, please, there's someone that can help me.
I have
table id="..........." tablesorter class="........"
They are in the same line of code ad I'm able to scrape until the first element. For me it's important to scrape by the second one. I'm tryng different way but nothing

In the image, in the part highlighted on the left where there is the drop-down menu, it's possible to select the different American markets (Nasdaq, DowJones,
S&P500 etc.). When I select a market other than DowJones, the URL of the page always remains the same, while the part that I highlighted on the right changes (tablesorter class = "............").
In my sheet, I've done this but it can't allow me to scrape different market (only the default table thay you see when open the webpage)

Your main problem is that IMPORTXML can only retrieve information from static content in websites. Therefore, any content inserted dynamically can't be retrieved by this function.
In your case, you can check what content is not static by heading over to the website https://it.investing.com/equities/americas and then disabling JavaScript on it. To do so if you are using Chrome please follow this guide.
As Javascript will add dynamic content to the site, when you disable it you will observe that the information subject to change with the dropdown doesn't actually change which means that it was dynamically inserted and therefore can't be accessed by IMPORTXML. I have attached an image below showing this.
As a workaround to this you will need to use other web scraping techniques.
so i need to develop an app using phonegap that creates a graphical display of solar wind data (exciting stuff i know...) from this website http://services.swpc.noaa.gov/text/ace-swepam.txt with a graph being made for 'ion temperature', 'bulk speed' and 'proton denisity' individually, however im clueless as to where to begin... im assuming i need to make use of the charts.js library or something similar, im assuming i can make a variable for the axis as the data will be changing over time but I'm more stuck on how to pull data from this website though to be included in my charts. Any info on this would be greatly appreciated!
Thanks,

Call the web service to get the data, then pass it to the charting library you're using. You'll use AJAX (XMLHTTPRequest) to get the data. There's all sorts of options out there for simplifying this (jQuery and other libraries make AJAX easy).
The service you're using is giving you the data as a text file - this can work, but you'll have to parse the data client-side which is not fun (or a good use of your phone's capabilities). Look for a service that returns the data as a JSON object, then you'll have the data in a format that can be more easily passed to the charting library.
On our website, it is possible to tag content by a country list. This country list could be implemented as a tag control but I'm concerned about mis-spellings creeping in over time. However, the country list is very long (150+) so not ideal for a dropdown multiple control either.
What I'm looking to do is have a control that has the same type + autocomplete functionality as the existing tags control but limit the possible values to those retrieved from a database table.
I also want to be able to list all tags that a piece of content has been tagged against as well as searching for content based on tags e.g. GetNodesWithTags
Has anyone developed anything like this before? I've had a look at packages etc but can't see anything similar. Does anyone have any advice before I start off?
Definitely, using Tags datatype for this may cause a lot of problems :)
In my opinion, the perfect solution will be to use nuPickers (https://our.umbraco.org/projects/backoffice-extensions/nupickers/) package and available there TypeaheadList Picker.
Depending of your additional requirements, you may use Lucene index / C# accessed source (totally custom - db, static, enum etc.) / XML file source as a prevalues for your control.
Then, you'll be able to create logic which will enable you to perform search based on this field as it will be a typical property with value on the nodes. Once again - suggested way is to use Lucene Examine index as it's tailored to be fast with searching. You can read more about searching with Examine here: https://our.umbraco.org/documentation/reference/searching/examine/.
Hopefully it will solve your problem.
I have a graph which I would like to represent using an image on a website. The problem is generating this image dynamically based on the current state of the graph.
I'm using ASP.Net MVC 3 with C#.
I've been thinking about generating the image on the harddisk using some tool(Graphviz etc.) and then passing the path of the file to the view.
Security isn't a real issue, as this is just internal project based work for now, it is much more important that its easy to implement.
I've been trying quickgraph, and eventually i've had it generating DOT files (apperently it ignores my attempts to make PNG's) but the code fails because the program don't have access to where the files are generated. I suppose this is easy to fix, though.
Do you have any suggestions to how I could do this (If i should do something completely different or how i can get the DOT files rendered as PNG)?
Best regards,
Daniel
Just wanted to note that I solved this using the Google Image Chart, they have experimental Graphviz support: http://code.google.com/apis/chart/image/docs/gallery/graphviz.html
Simply generate an URL and insert an external image on your page.
If the graph library allows you, write the result to a memory stream and place it in the Cache (System.Web.HttpRuntime.Cache) with a key.
Use that key to generate the img tag in the view and point to an action ('View'?) in a controller ('Image') like "/Image/View/392838".
Create this controller and view and serve the contents (make sure to include proper MIME type, content type etc.) from there.
In the cache specify a decent lifetime for the object, such as 15 seconds, sliding expiration.
I have a filemaker database that I need to be able to link records and all associated data (including container field data) to various points placed on a large PDF image, and then make that data appear via instant web publishing when someone clicks on the marker for that area on the PDF. For example the PDF may be an image of a car, and then I would have various close up images of issues with the car and descriptions of those images as records in the database. I would then want to drop points on the base PDF image and when you clicked on those points be able to see the close up images and other data related to those images.
I'm being told this is too much for IWP because:
I need to place the markers outside filemaker via PDF annotation
Filemaker IWP can't handle the number of markers that may be necessary (it could be up to 1,000 on an E sized image.
Does anyone have a work around or explanation why this is a problem?
If I understand correctly, you would like to setup a PDF with links that will open a browser and show data related to what was clicked. Assuming that is the case, the reason this wont work is because IWP does not provide a unique URL for a unique page. For example, here on StackOverflow you can directly link to any question based on its URL:
http://stackoverflow.com/questions/3207775/ -- this question
http://stackoverflow.com/questions/4973921/ -- some other question
IWP uses Javascript and session variables to manipulate the output to the screen, so there is no way to link to a specific section of your IWP site, since the URL is always something like:
http://yoursite.com/fmi/iwp/cgi?-db=YOUR_DB-loadframes -- Product A
http://yoursite.com/fmi/iwp/cgi?-db=YOUR_DB-loadframes -- Product B
http://yoursite.com/fmi/iwp/cgi?-db=YOUR_DB-loadframes -- Product C
Because of the limited nature of IWP, you will not be able to workaround this issue. You'll need to build your own web-interface using the Custom Web Publishing Engine, either using the built-in PHP extensions or some other technology where you invoke the XML publishing API.
I agree with Nate
IWP is the wrong solution to this problem. You'd be better off simply hosting those images on a webserver.
Now here comes the plug, you can use SuperContainer to really simplify the management of the images from FileMaker.
