Tableau Dimensions Continuous or discrete fields

The classification has an impact on what types of visualizations you can create as well as how they will look, t is easy to know if a field is being used as discrete or continuous based on its color. Blue indicates that a field is discrete, while green indicates that a field is continuous.

he thought that blue represents dimensions and green represents measures is the most common myth in Tableau. It’s easy to understand why because, by default, dimensions are categorized as discrete variables, and thus have a small blue icon in front of them in the dimensions shelf. Measures are categorized as continuous variables, so they are prefaced with a green icon in the measures shelf.

I assure you that the color-coding identifies discrete vs. continuous fields and not dimensions vs. measures. Measures can actually be used as discrete fields or continuous fields, and the same is true for some dimensions, such as dates.

Use Continuous dates for filters only and not as dimensions and Tableau cannot role it up for monthly or yearly continuous view.

Use discrete dates for dimensions.

Discrete fields draw headers; continuous fields draw axes

Discrete fields can be sorted; continuous fields cannot

Add Space between bars in Tableau chart

Adding “Apply” Button to A Filter Menu In Tableau

Adding An “Apply” Changes Button To A Filter Menu In Tableau Sometimes when a user is changing the options they want on a filter in Tableau, the chart updates as they change each option. This might not be the best user experience if they are changing many options and don’t want the dashboard to redraw the view until they have completed their selection. It is very simple to fix this – Tableau includes an “apply” changes option, which when enabled, means the dashboard won’t redraw to reflect the new filter choices until the user presses the “apply” button. Simply click the drop down arrow on the filter menu > go to “customize”, then click “show apply button”.

Using Special Characters in Tableau URL Parameters

Using Special Characters in Tableau URL Parameters When we try to use special characters in URL parameters, the URL parameter might not do anything, or an error might occur. The issue can be resolve by: Use one of the following workarounds: Replace the special character with the URL encoding sequence for backslash (\) (%5c) followed by the URL encoding sequence for the special character. The backslash is needed to escape the special character. For example, the URL encoding sequence for backslash and comma (\,) is %5c%2c. In the data source, separate comma-delimited field values into separate columns that can be filtered independently. In Tableau Desktop, use a calculated field to replace the special characters, such as commas or spaces, with hyphens (-). Cause The browser cannot parse the special characters used in the URL. Additional Information The error varies depending on the browser and special character being used. Networ...
