Is there a way to format scroll bars in Tableau? - tableau-api

I'm using Tableau to create dashboards visualising data that often require users to scroll to view the full page. But the scroll bar for the page is thin, grey and difficult to see.
Many of our dashboard users aren't the most technically fluent and are feeding back that they struggle to find/use the scroll bar.
Is there a way to format the scroll bar to make it larger/change it's colour?

Tableau doesn't allow users to change or format the visual scrollbars,
You can embed your dashboard and using CSS you can very well format your scrollbars.

How to fix the shape of the dashbord, esp. its parts?

I have built my first dashboard in tableau. When I am logged in and look at this, it looks fine, it consists of 2 horizontal blocks (on the left a double one, on the right it consists of three vizes). When I am logged out and look at the dashboard the right part shows only 1st viz correct, the other two are diminished and you can bearly see them. What might be the reason?
There could be a few things going on. Without a picture, it may be one or more of these:
Use Layout
Containers.
The layout containers will ensure that each part of the dashboard is
exactly where you want it relative to a parent container.
Use tiled
layouts. Floating layouts may cause dashboard parts to be in different places depending on the screen size.
Check to see if you are using Fixed, Automatic or Range sized dashboards. These can also make a difference in appearance based on screen size.
If you are using custom fonts, install them on server to ensure this isn't a part of the problem.
Please do share a picture (or preferably, the workbook) so further investigation can happen.
In the Dashboard tab -> Layout pane, check the Item hierarchy.
When a viz/sheet is dragged and dropped on to the dashboard, tableau, by default arranges them in tiled container.
If you have adjusted the width manually, disable the option fixed width which is pin symbol when sheet is selected.
Make sure that no tiled containers are present and all the sheets are dropped into respective Horizontal containers.
Adjust the width of the viz in the sheet to fit in the view.
These are some common resolutions. Share screenshot for much accurate solution.

Xamarin Forms MultiPage<T> example

I am thinking to implement a custom tabbed page with some custom functionality and I thought about using MultiPage.
I am thinking about that because it seems to be the base class of the Forms's TabTabbedPage and would like to actually have a page at the bottom to display the buttons and the top space to display come content pages based on the selection(of the user).
Currently I only added 2 pages on the MultiPage and the last page from the data set is being displayed but I can't shrink its height so that I can add another content page below to add the buttons. I tried to set the HeightRequest on the pages but with no effect.
Does anyone have at hand some samples involving the MultiPage or knows how to change the ContentPage width or height?
Thanks a lot!

EvoPdf Page backgrounds and Margins

I am converting HTML pages using EvoPdf and would like to add a background image. I am generating documents and would like to add a cover page, I am doing this by prepending the HTML for the cover page then putting a page break directly after.
I am using this demo as a guide http://www.evopdf.com/demo/HTML_to_PDF/PDF_Pages_Background/Add_Elements_in_Background.aspx and have found that I need to remove the page margins for the image to cover the whole page otherwise it sits inside the margins.
If I remove the margins this means the content that flows over pages now starts directly at the top of the page and flows right to the bottom. I can fix this for left and right margins by putting this in the HTML but this does not work for top and bottom margins that flow over pages. (see the generated PDF from the above demo)
Is there a way to set the PDF page background irrespective of the page margins? I have been looking at creating multiple documents with their own configuration and merging the PDF's but I really want to avoid this.
You can set up a header and footer with the heights you wanted for the top and bottom margins, and then choose to not display them on the first page. This should give you the effect you're looking for.
You can find more information about how to do this here: http://www.evopdf.com/demo/HTML_to_PDF/Headers_and_Footers/HTML_in_Header_Footer.aspx

Background Image not Aligning with Bubble Chart in SSRS

I have a background image for my bubble chart in SSRS (2008).
On the Design tab, the background image stays behind the bubble chart.
When I run the report (preview), the background image appears below the bubble chart - not behind it. I've set the background image as 'Send to Back'.
I assumed it should always stay as back of bubble chart.
How do I ensure that it stays fixed behind the bubble chart?
From the bubble chart graph, I have no option of filling the background with the embedded image.
According to this SSRS documentation, overlapping report items are not supported in preview mode, nor are they supported in HTML, Word, Excel, and several other important export formats. They are, however, supported in .pdf, and I've tested this to make sure that it works - even when the preview bumps the items so that they do not overlap, an exported .pdf will show them overlapping. So depending on the format you need, having overlapping report items may or may not be possible. If it is not possible for your required format, start looking into alternatives, like cropping your image into four separate images that surround your chart, and then keeping the chart as a fixed size in your report.
Oh, and I'm not sure what you mean by saying "From the bubble chart graph, I have no option of filling the background with the embedded image," if you are saying it won't work for your design purposes, that's fine. But I am able to set a background image in a bubble chart using the Fill section of the properties tab for the bubble chart to select a background image.
Edit: I am using Visual Studio 2008 as well. The properties window for the bubble chart looks like this:
Since it sounds like you already have the image you want uploaded to your project, you can choose "Embedded" for your source and then find the image in the Value dropdown.

Appcelerator: Pagination for Views in IPhone

I want to show remotely fetched records and want to display in same format as Apple shows Icons on Home Screen. I also want pagination ( the dots on bottom) for indication of currently selected page. How could it be achieved?
I believe you're looking for the ScrollableView component. Use the HTTPClient to retrieve your data from the server, create views/imageviews/etc from the data as appropriate, then add the views as children to the ScrollableView.
