-Take time to select images -Focus on colors and fonts -Follow the familiarity -Value the visual hierarchy -Add variety to visual communication -Make responsive values -Select appropriate animation styles
What are the five significant attributes of storyboards?
1. Level of detail. The level of detail present in a storyboard must take into account how many objects and actors might be present in a particular frame, the level of phot-realism incorporated by the designer, and the designers choice to display the entire scene or only details of the interface. 2. Inclusion of text. Designers can include text either through tagline narrations for each pane or within individual frames as speech, thought bubbles, or labels and signs that would be present in the real life environment depicted in the storyboard 3. Inclusion of people and emotions. Storyboards can include renitions of human users demonstrating interactions with an interface. Designers can also use these characters to build empathy for potential users, display motivation, or convey other intangible elements, such as how the application affects the user. 4. Number of frames. The number of different panels present in a single storyboard can vary anywhere between 1 and more than 20 frames, although the majority of storyboards we collected included between 3 and 6 frames. 5. Portrayal of time. Designers can explicitly indicate time passing within a storyboard or use transitions that convey changes over time as suggested by Eisner.
What are the variations of a column bar graph?
3-D Bar Graphs; 3-Axis Bar Graphs; Stacked Bar Graphs ; Line/Dot Bar Graphs; Histograms; Pictograms.
What are the uses of a radar chart?
A Radar charts are very useful when comparing performance/measurement results from different sources. Obviously, the greater the area covered by the plot, the greater the overall value. Through comparison and analysis, people can figure out their current situation: improving or falling behind.
What is a Radar Chart?
A radar graph is composed of a set of axis radiating from the center. Each axis represents a different property or value. Each plot on the radar graph consists of a point on each of the axis, which are usually connected. Each plot is assigned with different color. If the area enclosed by the lines is colored in, the shading is usually semi-transparent.
What are the variations of a line graph?
Area Line Graph
What are the variations of a pie chart?
Donut Graph (used a lot in advertisement)
What is Explanatory analysis?
Having specific thing you want to explain, a specific story you want to tell
What are the disadvantages of a radar chart?
cannot compare more than two or three different plots at once; without coloring, can be difficult to tell which points belong to who; too many axis makes it difficult to read less intuitive than other graph types
What are the advantages of a bubble graph?
displays three variables without using 3D graphs; visual size makes it very easy to make relative comparisons; Conveys same information as a line graph
What are the disadvantages of a bubble graph?
due to circle sizes, can be difficult to ascertain actual values; difficult to read and understand; cannot be used to display a lot of data.
What are the advantages of a stock graph?
excellent at displaying financial data
What are the disadvantages of a pie chart?
hard to compare two data sets; the total represented by the chart is unknown; difficult to understand without labels (especially with similarly sized segments)
What are the disadvantages of a scatter plot?
impossible to label data points, hard to find out exact values; error bars and too many data points can quickly make graph unreadable; cannot show relationship between more than two variables at once
What are the disadvantages of a line graph?
multiple lines on the graph, especially unrelated can be confusing; difficult to make out exact values for data
What are the advantages of a radar chart?
primary way of displaying more than two or three values at once; excellent way to get a "feel" for data;
What are the advantages of a pie chart?
provides an excellent visual concept of a whole; clear comparison of different components, highlight information by visual separation of a segment, easy to label, lots of space.
What are the disadvantages of a column bar graph?
require additional written or verbal explanation; can be easily manipulated to give false impressions.
What are the advantages of a line graph?
show trends and relationships between data better than other graphs; compare trends in different groups of a variable; clearly show error values in the data; Usually simple to read and understand
What are the advantages of a column Bar Graph?
summarize a large dataset in visual form; easily compare two or three data sets; better clarify trends than do tables; estimate key values at a glance.
What are the disadvantages of a stock graph?
very specific use; too many types of graphs combined together can make it very difficult to read.
What are the uses for a column Bar Graph?
Bar graphs are used to highlight separate values, especially the differences between these values. They are extremely useful for comparing values in different categories and can be used to describe the relationship of several variables at once.
What are the uses of a bubble graph?
Bubble charts are often used in business to visualize the relationships between alternatives investment in dimensions such as cost, value, and risk.
What is a bubble graph?
Bubble charts useful for comparing the relationships between data objects in 3 numeric-data dimensions: the x-axis data, the y-axis data, and data represented by the bubble size. Essentially, bubble charts are like XY scatter graphs except that each point on the scatter graph has an additional data value associated with it that is represented by the size of a circle or "bubble" centered around the XY point.
What are the advantages of a scatter plot?
Clearly indicates data correlation (illustrates positive, negative, strong, weak relationships); method of illustration non-linear patterns; shows spread of data, outliers; clearly demonstrate atypical relationships; used for data extrapolation and interpolation
What is a Column Bar Graph?
Column graphs typically have two axis, an x-axis (horizontal) and y-axis (vertical). The x-axis is usually labeled with the categories being compared. The y-axis is generally labeled with the frequency, or value of each category.
What are the uses of a line graph?
Line graphs are typically used to show how a value changes over time, though the independent variable can really be anything. Since they are most commonly used to visually represent trends over time, they are sometimes referred to as time-series charts.
What are line graphs?
One of the most popular types of graphs, line graphs has two axes.The horizontal (x-axis) is for the independent variable, and the vertical axis (y-axis) is for the dependent variable. Points on the graph are connected by lines, hence the name.
What are the uses of a pie chart?
Pie charts are typically used to summarize categorical data, or mostly percentile value.
What is a pie chart?
Pie graphs, in their simplest form, are circles subdivided into different colored areas.
What are scatter plots?
Scatter plots are generally composed of two axes. Both the x-axis and y-axis represent a range of values. Where the axis intersects is always (or should be), (0, 0). Data points are plotted according to their x/y-values, but they are not joined.
What are the uses for a scatter plot?
Scatter plots illustrate paired data, that is, information regarding two related variables. It is particularly useful when one of the variables (represented by the y-axis) is dependent on the other (represented by the x-axis). The resulting pattern (after all the points have been plotted) will indicate the strength of the correlation between two variables. They are used primarily in science to establish relationships.
What are stock graphs?
Stock graphs are usually a hybrid of various graph types. However, one type of graph is specific to stocks. Each bar contains two extra dashes, one on the left and on right. Stock graphs are always seen on a two axis system and are always plotted against time (time is on the x-axis) and usually a dollar value is used for the y-axis.
What are the uses of a stock graph?
The ticks to the left and right serve to indicate the starting and ending value of the time interval taken up by the bar. The actual endpoints of the bar are the high and low values reached during that time period. These special bar graphs are usually combined with conventional bar graphs or line graphs which show an average value for each time interval. Stock graphs are used almost exclusively to visualize financial data.
what is exploratory analysis?
What you do to understand the data and figure out what might be noteworthy or interesting to highlight to others.
