Drawing borders around a group of components in Matlab Appdesigner

I am using Matlab 2019b Appdesigner.
I have an app with many buttons, user input boxes etc and for making the navigation easier, I want to draw borders around a group of components which are under the same functionality. How can I do this?
Edit: Thanks to Rotem, I see that I can use the Panel Container for this. But is there a way to change the color or width of the border. I see only option to do it if it was created with GUIDE, but not Appdesigner.

Is there a way to make a Pie Chart with iTextsharp?

I need to make a Pie Chart for a new PDF document I'm developing but I haven't found a way to make it happen. As long as I've been researching there's no obvious way to draw a piece of a pie chart. just a full circle witch doesn't help.
My goal is to have a pie chart where each piece can be independent and have different size and radius.
I've tried to use circles and divide the circle with lines but it would be better if I could draw each piece of the pie chart independently, so i could make the design more appealing.

How can I get the frame of one of the x-axis labels in the horizontal bar chart of Charts?

I've created a bar chart by using the Charts framework. Currently, I'm trying to draw a red circle underneath the current day. However I'm not able to get a reference to the bounds nor the frame of the x-axis labels. How could I achieve this?
What I want to achieve is something like the added image

Line Chart axises layout

I have a line chart as it is showed bellow.
How can I make the x-axis showing off all the data (I need the chart to be in small size), for example as it is appear in the preview bar (I mean by preview bar the scrolling bar under the chart to explore the x-axis value, which I highlighted in red in the second photo). In other words, I want to see somehow the whole data of the x-axis in the chart at once without the preview bar.
I hope someone have an idea to help me out, and much thanks in advance.
I think the answer is that this is a feature, not a bug - as Sense is built to re-size and tailor the view for any screen size you lose control over the minutiae such as what parts of the chart to show.
Sense will always format itself to fit as per predetermined rules in the background.
That being said, the slider at the bottom of the chart displays the entire chart and users can expand the chart to fill the screen. So it might be an idea to instead of trying to fit Sense to your requirements to readjust your users expectations to what Sense can offer.
If you were able to see all the data in such a small chart, it would be unintelligible.

Restrict the dragging/movement of smart lines in fusioncharts to avoid weird shapes

I'm creating doughnut chart with smart lines and labels. When there is only one item in the chart, I'm facing an issue. If you drag the smart label or line around, the chart changes its shape in some angles. When the doughnut chart has 3-4 items this doesn't occur. I have attached screenshots. Is there any way to fix this or disable the rotation of chart when lines/labels are dragged?
To restrict the dragging of smartlines, add "enableRotation": "0" to the chart object. Here's the updated fiddle http://jsfiddle.net/g1254w67/19/
