I must be missing something obvious:
I'd like to add an indicator for a 2d array to a vi. The display should have 2 columns and 20 rows to display a 20x2 uint16 array.
When I create an array view and add a numeric indicator, I can extend the array by extending the array with the mouse, but it keeps having only 1 dimension, either horizontally or vertically.
This is Labview 2016 on Linux. What do I miss?
Just drag the mouse in the Index display to the left and increase the dimension.

I want to have on the same page a pie chart and a bar chart, with trellis pages.
They both have 5 columns as trellis, so 5 different pages that you can visualize by scrolling down.
However, I would like to display the same pages at the same time for both graphs. For instance, let's imagine I'm on the pie chart, I scroll down one page - and so my pie chart is on page2 - I want my bar chart to automatically go to page 2 as well
I tried to use markings but although it links a bit the two graphs, it doesn't change the trellis pages automatically
Does anyone know how to do this ?
as #scsimon mentions, there's no native feature (nor API method, AFAIK) for this using a trellis. however, you can create a Property Control (I'd use a dropdown) in a Text Area, then use the same Document Property to your chart in a Limit By expression.
little more detail, assuming a data table like this:
A B CATEGORY
1 2 red
3 4 red
5 6 green
7 8 green
9 10 blue
11 12 blue
add a Text Area to the page and edit its contents
add a Property Control
click New to create a Document Property, give it a type String and a name category
change Set property value through to Unique values in column and choose the "category" column and click OK
save the Text Area contents
in your Pie Chart's Properties dialog, go to the Data page and look for Limit data using expression. click Edit
set the expression to: [CATEGORY] = "${category}" (don't forget the quotes or the Document Property won't be treated as a string and you'll get an error)
repeat steps 6 & 7 for your other chart
As #scsimon mentioned in the comments, it seems to be impossible. I found a way to have a similar representation though without using trellis visualization, by using text arena
I created a list box that contains the 5 columns I want to visualize, and then I select this list box as the vertical axis variable of the bar chart and the sector size of the pie chart
Then, by clicking on my list box, I can have a synchronized Pie chart and Bar chart (a bit different from what I expected but it also has some advantages like a multiple scale since a new graph is generated independently of the other variables)
how can i get the percentage of an element depending on the whole layout? I tried to change the rulers to percent but the values are not accurate (859%, 1100%...).
1.Change to procent,
2.view info panel F8
3. select to layer with the object.
4. cmd+t or ctrl+t now you se the element with and height with 1 decimal.
I made this boolean array.
I want change the color of first boolean component as red, and second as blue.
This picture is what I want.
But when I change color property, three booleans change their color with together.
Is there any way to change color of boolean components, respectively?
Short answer: Just replace the boolean with a color box, as shown in the links in the other reply. It will simply be an array of color boxes instead of an array of booleans.
Long answer: An Array control contains an inner element control. The only property that can differ between elements of the array is the Value property. All other properties are rendered identically across elements of the array. If you need to differentiate the elements based on something other than the Value, you need to either use a different control that renders the graphical aspect that you want as its Value (i.e. replacing the Boolean with a Color Box) or you need to break out the N elements that you want to display as N separate independent controls and manage the updating of the display by yourself through code on the block diagram. This generally means creating your own scrollbar control or numeric control for controlling the index of the array.
You can always try to change your approach a little, try using clusters and if you need to use array, then create array of clusters. Here and here are similar subjects that should help you solving the problem with colors.
Can anyone help me out Why Only Legends section is displaying but Ring Chart is not displaying IF the data set has more data records say > 50. I have stuck with it.
Depending on the data, that may be too many values to display usefully. You can try the static method DatasetUtilities.createConsolidatedPieDataset() to derive a dataset that is "modified by aggregating all the low value items (those whose value is lower than the percentThreshold) into a single item with the key "Other".
Is there any other way to increase entire chart size?
I'd override getPreferredSize() in ChartPanel like they show here.
I am writing a WinRT app and need to change its layout in a snapped view. In a regular view details are displayed in grid of a following structure:
MainGrid: contains 2 rows, 2 columns (let's call them M11, M12, M21, M22)
DetailGrid: occupies rightmost column and upper row of MainGrid, contains 1 row, 2 columns of equal, so the layout looks like this:
M12 contains D1 and D2 layered horizontally
In a snapped view I want DetailGrid to be redefined so it has a single column and 2 rows:
M12 contains D1 and D2 layered vertically
If I didn't care about column width, I could use StackPanel instead of Grid to display details and simply change StackPanel orientation in a snapped mode from Horizontal to Vertical. But D1 and D2 must use all available space in a standard mode and have equal size, therefore I control them via Grid ColumnDefinition. But grid definition is not something that is easily controlled using VisualStateManager.
What do you think would be the best way to manage such layout?
Thanks in advance
Grid definitions are hard to control but I've found changing Grid.RowSpan or Grid.RowColumn span on the controls within the grid should be able to do what you need in snap view
