More Getting Started Stories
We all ask questions about our data every day. Some questions are about a status or situation. Some are about why something happened. In short, when it comes to data, we want to know what is happening, why it’s happening, and what insights need to be communicated with others. IBM® Watson™ Analytics can help you understand your data, find insights that are hidden in your data and provide you with answers to make confident decisions – all on your own. This tutorial uses sample data to walk you through the skills you need to get started. Each chapter covers a different area of Watson Analytics, from importing data to discovering insights to sharing these insights in a dashboard to social media analytics. Take 15-30 minutes to complete a chapter, or complete the entire tutorial in about 90 minutes. Getting started with IBM Watson Analytics Last updated: 2017-11-22
There’s a few different ways to apply filters to your visualizations in a dashboard. Here’s an overview of the different types of filters and how they work. You can filter visualizations in your dashboard in three main ways: Filter all visualizations in your dashboard Filter one visualization based on a column in the visualization (Keep/Exclude) Filter one visualization based on a column not in the visualization (Local Filter) What’s Filtered Right Now? To get started, here’s a quick way to check filter status. TIP: Click the Filter Status icon in a visualization to see the current filtering that is applied. Applying a global filter across all visualizations in the dashboard Use the data tray to configure a filter that applies to all visualizations in the view. This type of filter applies across all the tabs in the view for any visualization that uses that same data set. Click on a column title in the data tray and then click the filter icon. Select your filter criteria and then click away from the filter menu to close it. Here’s an example of a global filter for the Region column set to only “Mid-Atlantic” and “Northeast”. TIP: The blue line above a column in the data tray means that column has a global filter. Filter a single visualization using the Keep/Exclude option Use the Keep/Exclude filter to display or hide specific data points in a visualization. A data point can be an element or data point displayed in the visualization. For example, a bar in a bar chart, a bubble in a bubble chart, an item in a legend or an item on an axis. Right-click one or more data points in a visualization and then choose Keep or Exclude. The filter is applied to that visualization only. The other visualizations in the view do not update. After setting a filter, you can click the Filter Status icon in the visualization to see the current filter status. Tip: This type of filter can also be configured in the column panel when you edit a visualization. Filter a single visualization for a column not displayed Use the Local filter option to slice your data on a column that’s not displayed in a visualization. This type of filter is available only for visualizations you create in Assemble and does not update any other visualizations in your view. 1.Change the view into Edit mode and then click the Expand icon for the visualization. 2.Drag the column you want to filter on from the data tray to the Local filters option. 3.Select or type the criteria for the filter, and then click away from the filter pane. 4.Click the Collapse icon to return to the view. To verify the filter, click the filter icon on the border of the visualization.
