1.Introduction
In the previous article, we talked about the principle of visual dashboard design for web side -readability （How to design a Dashboard, Best Practices – Readable | SAP Blogs）.
We know that, readability guidelines can help you guys check your dashboards so that they can communicate information more accurately. In addition to web-side dashboards, mobile design has been gaining attention since the launch of SAP Analytics Cloud's social media integration services. In this post, I'll talk about the design points of a responsive interface for mobile.
1.1 “Content is like water”
When responsive interfaces became popular, designer Josh Clark came up with the phrase "Content is like water", inspired by the famous words of kung fu master Bruce Lee.

That's a good analogy. A good responsive interface is like the "flowing water" emphasized in Chinese kung fu. If you think of the screen as a container, the content flows in that container.

1.2 what is responsive layout？
Responsive design was introduced by Ethan Marcotte in 2010 to enable different ways of displaying the same web page at different screen resolutions.
From a technical point of view, when the width of your browser reaches a value ,also known as Breakpoint, the layout and style of the page changes significantly, which is the most important feature of responsive design - Segmented display.

In the SAP Analytics Cloud story, users can already design using a responsive canvas, and these responsive pages already support adaptive presentation on mobile.

2. Responsive design guidelines for mobile
For mobile responsive interface design, in addition to the readability mentioned in the previous article, we need to ensure that the user's browsing experience is smooth and consistent, with reasonable elements displayed in different interfaces. This means that the layout of the interface needs to be planned at the beginning of the design.
2.1 Fluid Images
Fluid images are the most common layout method for responsive interfaces, and it is often applied to the display of photographic images. When the width of an image is larger or closer to the width of the phone, fluid images are made to fit the interface by isometric scaling.

It is important to note here that fluid images are mainly suitable for scaling large resolution images to smaller sizes. If the image is small, enlarging it will affect clarity and readability. To avoid this pixel discrepancy, you may also choose to prepare multiple sizes of photos when building your website.
2.2 Adjustment of spacing
When there are more small elements in the interface, we choose to fit them into the mobile interface by adjusting the spacing. Like this bar chart（figure 6）, we only need to fine-tune the distance of each bar to adapt it to this canvas.

In addition, for page spacing, our colleague roy.jin, after testing different scale units, found that leaving 2% space on each side of the screen could improve the user's visual experience.
2.3 Canvas downsize
Being able to display a very large amount of data on one screen is a feature of the web side, so what do we usually do to adapt a page with a lot of data to the mobile side?
In order to adapt to the mobile width, we would reduce the canvas size of the displayed data and select the more priority data to be displayed and collapse the rest.

2.4 Pop-up box
Pop-up boxes provide a good option when you need more annotations for mobile data. You can set up pop-up box widgets in the SAC Analytics application, or you can use sub-panels to simulate pop-up box widgets.

It is important to note here that the size of the popup box widget is fully controlled by the system. If you have advanced needs, using the sub-panel to simulate the popup box widget allows you to arrange the size and position more rationally.
2.5 Fixed-size content
A Fixed-size content is, as the name suggests, an element that is fixed to a certain location on the screen, such as a centered display, so that no matter how the canvas changes, the size and position of the element no longer changes.

2.6 Component Replacement
Due to the large differences in operation and screen size between mobile and web, the changes in the plane size and position of components in responsive layout sometimes cannot meet the higher-order needs of users. This is when we often use the idea of component replacement to enhance the layout design.
