I have a sidebar that works here but is not alphabetized: www.wrh.noaa.gov/mfr/rec/v2/
I've tried to alphabetize here: www.wrh.noaa.gov/mfr/rec/v2/index_sort.php, but now the sidebar text links aren't linking to the correct map. I understand why this is (have reordered the array, and it doesn't know how to connect to the original "batch" array), but I don't know how to order the list on the sidebar yet keep the connection between the links and the map. I know I could simply order the spreadsheet which is converted into the xml document alphabetically, but I need it to remain in the order that it is...which isn't alphabetically. So I need to do this ordering within the script it seems. Any suggestions? It would seem that I could order the way I display the names on the sidebar without changing the "myclick(i)" number that matches the "batch" marker objects. I can clarify further if needed. Thanks for any help,

You just need to pay attention to the order you do things in. You can either sort the array, keeping a copy of the original, and referencing the markers there by there original index:

Or you can sort the array (changing all the indices), then recreate the sidebar to match:

I’m relatively new to Tableau and have a question.
I want to create a heatmap show the location of two different groups of people. I’ve learned how to overlay maps using dual axis but the problem I keep running into is that each group requires different filters to aggregate the data the way I want.
Basically, I want to show:
Group1.id IF charge_id IS NOT NULL
And
Group2.id IF status = ‘ACTIVE’
Whenever I create a calculated field with one of the above calculated fields and place it in the filters box it automatically removes the other group from the map because the filters contradict one and other.
Help is much appreciated 😊
The filter shelf applies to the entire worksheet, so if you want to “filter” each field selectively, use an IF expression in a calculated field that evaluates to null when you don’t want that field in the view.

I'm working on a graphical shape editor that uses the QGraphicsScene/QGraphicsView as its basis. I have a lot of experience with the scene/view framework and understand it fairly well. The issue that I'm having is that QGraphicsScene::items always returns items in the insertion order (either ascending or descending) regardless of the Z-order or the use of QGraphicsItem::stackBefore call.
The issue is that, as with most graphics editors, I need to be able to move shapes forward or backward in the stacking order. At the end, to save the resulting data, I have to traverse the list of the items in the scene and save each item's data in whatever format I'm using.
The only way that I've found to do this is that I have to remove items from the scene and reinsert them in the desired stacking order. In this particular task, it's a small number of items and happens without noticeable delay, but in a related editor, it could be many thousands.
While the QGraphicsItem::zValue and QGraphicsItem::stackBefore allow me to influence the drawing order, neither of them changes the order that gets returned from QGraphicsScene::items. Since the data I ultimately save needs to reflect the drawing order, I have to remove and reinsert to get the correct ordering at the end.
Questions:
Have I've overlooked any other techniques for managing items within the scene that will influence the results of QGraphicsItem::items?
Or is there another method for traversing the items within the scene that will give me the drawing order?
I can confirm that QGraphicsScene::items() and items(sortOrder) return the item list in the original creation and stacking order, which does not at all agree with the docs.
However, I found that by using
QGraphicsScene::items( QGraphicsScene::itemsBoundingRect, Qt::IntersectsItemBoundingRect, sortOrder) I do get the items in the correct drawing order, so this function apparently takes calls to QGraphicsItem::stackBefore() into account.
i don't use the z-order feature so I can't comment on whether that works in this scenario or not.
Is there a way to automatically set a weight to nodes in Drupal? I am wanting to achieve this, because I am creating a blog layout and I want the most recent articles to appear on the top of my secondary menu rather than on the bottom.
By trying to sort by a dynamically iterating weight field, you're adding complexity to something that is really quite straight forward. This scenario is best handled by sorting by the created, or updated date of the node. I mean, by definition, that will allow you to sort by the most recent article. Heck, even sorting by the node ID would be better, since you have a value that's automatically increasing for every item that's created.
A weight field should only be used when sorting needs to be empirical, like a todo list or something. If you're using a weight field because you want to adjust the sorting of an article later on, you would still get the desired result by sorting by multiple columns (i.e. weight ASC, created DESC).
I'm writing a Notes Client application. Web compatibility is a secondary concern. The language is LotusScript.
The specification: a form to enter lines from receipts. The lines are all saved as part of the same document so that they can be signed as an atomic unit.
When a line is added, it is to be formatted into a table for presentation. Ultimately, this architecture is like an input/datastore/presentation split.
I've managed to get the data stored and signed, and I think I've managed to get it deserializing properly (the LotusScript debugger makes it difficult to see, but it looks right). The problem now is the UI.
Looking at the Programmable Table, it is always a tabbed table with only one row shown per tab. I need a programmable table which can dynamically have rows added to it for display, without forcing new tabs to be created.
This suggests that I would need to use a Rich Text field to contain a table, but thus far my attempts to get anything to display when I try to update a Rich Text field in edit mode have failed. I am forced to conclude that it is impossible.
I cannot figure out how I'm supposed to do a dynamically-displayed list of tabular data like this. Any advice?
Most people just create a table with one row and N columns, with a multi-valued field in each column, and use code to append values to each of the fields in parallel. You don't get borders between rows this way or the ability to do variable formatting of cells, and you have to be careful to avoid letting data length exceed column widths in order to keep everything aligned properly.
If you truly want a dynamic table for presentation with all the bells and whistles that you can get in terms of cell formatting, then the Midas Rich Text API from Genii Software is a commercial solution that can do the job.
I blogged about this a couple of years ago: http://blog.texasswede.com/dynamic-tables-in-classic-notes/
This is a non-XPages solution, but of course you can also use XPages to achieve the same/similar result. It does not use tabs, as each row is a separate table.
Alternatively, you can build your Rich Text Table in another NotesDocument, which you then save. Then use NotesUIDocument.ImportItem (which is undocumented, but present in the R8.5 mail template) to update your NotesUIDocument.
Don't forget to delete the other NotesDocument when you're done.
Another option is to build the table in HTML in computed text, and re-open the document every time you modify it. I have inherited a system that does that, and I hate it...so be warned :)
I'm having a bit of a time trying to get Dojo grids (1.5) to play nice. Specifically I've spent about two weeks of work trying to implement a grid that allows for our result set data to collapse into rows, where rows can be expanded. Data comes in as a full set in JSON format, using ItemFileReadStore as the store. Any subsequent sorts or pagings are handled by GETing a new json from the application, and passing in new query parameters in the url.
The nested data was only two layers deep - a top layer to always be displayed and an array of child data with identical structure as the top layer. Each node has a unique ID and a cluster ID - on a parent node the unique ID and cluster ID will match.
I was initially very excited with TreeGrid - but I couldn't see how I could format it to do what I needed - namely eliminate the 'summary row' and one extra row full of null cells (???) that I just couldnt figure out how to remove unless I focused the query to only one cluster. I studied the test examples, built many test pages myself, tried to understand the forestModel, which for what I could tell was unnecessary... I found so little documentation, and sources I found online hinted that TreeGrid might not be reliable...
So I decided I would try to implement the expandable/collapsible rows in dataGrid.
I flattened the JSON data and added another attribute to indicate being a top level node ('alwaysShow' = true). I built my grid programaticaly and applied grid.filter() to pull only those top level nodes. I modified that filter by extending the ItemFileReadStore _FetchItems "filter" method to allow for OR querying instead of AND, and also modified it to allow for keys to point to arrays - when a top level node (small +/- icon in the cell) is clicked, the cluster ID of the parent node is added to the grid.filter.allowed[] and the filter is updated, allowing nodes with that cluster_id value to be displayed.
This worked fine on my small test set of five records (although id say a little slugish...) - but now I am pulling ~900 rows back from the application, and on expanding large clusters (~80 rows) I am seeing a very long flash of blue and white on the filter updates. I've spent most of my day trying to step through in firebug to find where its happening, but the dojo logic is so spread out. Seems to be happening before the call to _Grid.js defaultUpdate.
Its so bad that I am considering trying again with TreeGrid. Im also considering just doing this by hand... Im kicking myself for spending so much time trying to get Dojo to work to begin with. I would also consider a commercial "JSON->table with collapsible row" library if anyone has any recommendations...
Any suggestions or insights? Familiarity with the flashing problem or how I could adapt TreeGrid to my needs? I'm aware this is a bit of a rant... Many thanks for any help.

EDIT: I eventually gave up trying to get Dojo to do what I needed and coded it myself in less than a day. Not the best use of three weeks...
EDIT:
I just found a solution that works for me, I have added the following CSS:
.dojoxGridSummaryRow {
visibility: collapse
}
Basically the summaries are probably still created but they are not visible nor taken into account in the table layout. That's good for me. Hope this will solve your issue.
This won't help but just to let you know that:
"- but I couldn't see how I could format it to do what I needed - namely eliminate the 'summary row' "
is the very EXACT same thing I'm trying to achieve and did not find the solution even though this looks like a very simple feature... Will let you know if I found a solution...
