Different types of charts:-
BAR CHART :-Use bar charts to compare data across categories. You create a bar chart by placing a dimension on the Rows shelf and a measure on the Columns shelf, or vice versa. A bar chart uses the Bar mark type. Tableau selects this mark type when the data view matches one of the two field arrangements shown below.
LINE CHART :-A line chart is used to represent multiple data points connected together with a single line. These data points on a plot are called Markers. Line charts are used to analyze trends that datasets reveal. And for the same reason, line chart
or lines in a plot are important in forecasting and trend analysis.
PIE CHART :- pie chart represents data as slices of a circle with different sizes and colors. The slices are labeled and the numbers corresponding to each slice is also represented in the chart. You can select the pie chart option from the Marks card to create a pie chart.
Maps ;- Tableau is designed to make the most of geographical data, so you can get to the “where” as well as the “why.” With instant geocoding, Tableau automatically turns the location data and information you already have into rich, interactive maps with 16 levels of zoom—or use custom geocodes to map what matters to your .
Density Maps:-These types of maps are called heatmaps, or density map. Tableau creates a heatmap by grouping overlaying marks, and color-coding them based on the number of marks in the group. Density maps help you identify locations withhow greater or fewer numbers of data points.
Columns shelf: Longitude (continuous dimension, longitude geographic role assigned)
Rows shelf: Latitude (continuous dimension, latitude geographic role assigned)
Detail: One or more fields with many underlying data points
Scatter Plot:- Use scatter plots to visualize relationships between numerical variables. In Tableau, you create a scatter plot by placing at least one measure on the Columns shelf and at least one measure on the Rows shelf.
Gantt Chart
Gantt charts display a project schedule or show changes in activity over time. A Gantt chart shows steps that need to be completed before others can begin, along with resource allocation.
Bubble Chart:- se packed bubble charts to display data in a cluster of circles. ... Tableau displays a bar chart—the default chart type when there is a dimension on the Columns shelf and a measure on the Rows shelf.
Treemap:-Tableau Desktop. Use treemaps to display data in nested rectangles. You use dimensions to define the structure of the treemap, and measures to define the size or color of the individual rectangles. Treemaps are a relatively simple data visualization that can provide insight in a visually attractive format.
Design methods are procedures, techniques, aids, or tools for designing. They offer a number of different kinds of activities that a designer might use within an overall design process. ... Design methodology is the broader study of method in design: the study of the principles, practices and procedures of designing.
