To make it presentable we will customize the title, colors, and orientation.Īs we can observe, on July 12th, 2019, the region of WR and the state of Maharashtra had the highest power consumption. Each bar is now represented by power consumption per Region, State, and Date. To create a bar chart, we move the newly created field to Columns and Usage to Rows shelf. After resolving the issues, we click on “OK” to add a new discrete field with Dates that will show in the Data tab. To resolve this issue, we will convert the datetime value to a string using the `STR` function.Īdd the Dates field within the `STR` function using round brackets, as shown below. When we attempt to add Date with States and Region, the error following error is prompted: “Can’t add string and datetime values”. How to Concatenate String with Non-string Values?Ĭoncatenating a string with a non-string field will prompt an error, as you cannot add numerical values to string values. The resources tab will answer all of your queries related to Tableau and business intelligence careers. If you are a complete beginner and this tutorial seems overwhelming, then check out DataCamp’s Tableau Resources. Within the WR region, Maharashtra state has the highest power consumption from the year 2019 to 2020. To learn more about customizing charts, check out Tableau Dashboard Tutorial. To make our chart more presentable, we can customize it by adding a title, changing the colors and orientation, and sorting values in descending order. The bar chart shows the combined Region with States name. In the next step, we are going to plot a bar chart using the newly created fields “Combined Region and State” and “Usage”.Īs you can observe, we have successfully concatenated two fields into one. Next, we will add the States field using the “+” mark and type the field name in square brackets, as shown below.Ĭombining two fields does not prompt the error, so we are going to click on the “OK” button that will add a new discrete field to the Data tab. Why are we adding separators? To make sure our field values are readable. Make sure your separator is in double quotation marks. In our case, we will pick and drop the Region field into the input box that will show as ``.Īfter that, we add a field separator using the “+” mark. To add a string field, you can pick and drop the field into the input box, or you can type the field name in square brackets. To join fields, we need to create a new calculated field by clicking on a small, downward-pointing arrow in the Data tab, or we can right-click anywhere in the Data tab to access the option.Īfter clicking “Create Calculated Field”, the popup window will appear where you can rename the field to “Combined Region and State”. We can avoid this by concatenating multiple fields into one. You will see numerous separators dividing the bar chart into smaller chunks. If we add multiple fields to the Columns shelf, the results will be chaos. Non-Concatenate Tableau Worksheet Example How to Concatenate in Tableau? This results in a sum of power usage per state bar chart separated by regions. Similarly, we pick and drop the Usage field to the Row shelf, as shown below. In the next step, we pick and drop Region and States fields to the Columns shelf. The `long_data_.csv` file consists of Dates, Regions, States, Latitude, Longitude, and Usage(MWh) columns. You can download the file from Kaggle here. In our case, it is a CSV file containing power consumption data in India (2019-2020). To initiate the workspace, we need to connect the data source in Tableau Public (Desktop). In this tutorial, we will learn about non-concatenate examples and follow a step-by-step guide to concatenate multiple strings and non-string fields using Tableau functions. You can also combine multiple string fields with non-string fields by using the string conversion function. String_field_1 + string_field_2 + string_field_3.+ string_field_n In Tableau, you can create a calculated field and combine multiple string fields using the “+” mark. In Tableau, two or more string fields are combined to create another field. The concept of concatenation is about combining multiple fields to create a new one to serve a particular context-based purpose.
