Dashboards serve as a visual representation for a company to monitor progress and trends, not only among themselves but against other companies as well. Dashboards and visualizations contain data that is updated in real time. For example, if the underlying data in an Excel spreadsheet were to change, so would the visualization.
Power BI Power BI provides the tools for a user to create different types of visualizations to communicate the data that they are using. Some examples of these visualizations include graphs, maps, and clustered columns. Power BI pulls data from Excel that can be used to create dashboards and visualizations. Whereas Excel does not import data from Power BI. Excel is typically used for less data and Power BI is more complex. Power BI can be used to display trends over time. For example, a company can create a time plot that shows its costs and revenues over a certain period. The data can then be arranged to show per day, month, quarter, year, etc. This requires simple formatting tools so the data can quickly be changed and compared. Power BI allows the user to customize their visualizations by adding colors and labels. In addition, when the user clicks a data point, they are able to understand what the point or selection is showing. Power BI also has a commonly used map feature where businesses can view their sales and earnings across different states and countries. Places with the highest amounts of data will appear larger in size. For example, a state with the most revenue will be bigger than states with less data. Power BI is also interactive in that in any type of map a person can expand a specific category to look deeper into the data contained.
Tableau Tableau is another program that allows users to create dashboards. Allegedly, One of Tableau's biggest advantages is how much data it can hold. Tableau can hold an unlimited amount, whereas an Excel spreadsheet has a capacity of 1,048,576 rows. However, it is possible to hold and analyze effectively billions of rows in Excel, using its Power Pivot feature. Tableau has the ability to make interactive dashboards by clicking into a specific point. For example, you can have data be displayed within a map. By clicking a specific state or city you can get a closer look at the data contained within that location. Filters and parameters can also be added. For example, if one were to analyze revenues across the United States you could set a parameter to only show salaries within a particular range. Once set, only states within this range will be highlighted.
Excel Excel has many tools that help the user not only implement data but also visualize data. Excel has many built in functions that can help break down data and also separate data by scenarios. The user can easily download and add files to their Excel sheets to use for their data. Other tools Excel offers is the use of conditional formatting and basic
pivot tables and charts. Excel allows the user to reference other cells which ultimately allows for complex computations to be made and conclusions to be drawn from data. == Guidelines for dashboard design ==
