In this blog I would talk about creating Donut chart in tableau step by step ,
Step 1: Import the excel file in Tableau . The format of the excel file is as under. The excel has three columns : Category, Sales and the year for sales .
Step 2: In the worksheet tab of tableau , create two measures 0, 0(1)
Step 3 : Bring the measures 0 and 0(1) in the Rows shelf and select dual axis for SUM(0)
Step 4 : Go the All under the marks card and remove the measure name from the colour.
Step 5 : Under the marks card select SUM(0(1)) and select the chart as pie.
Step 4 : Bring Category to the colour .
Step 5 : Increase the size of the chart.
Step 6 : Add Sales to Angle.
Step 7: Place the Sales measure on the Label and add a quick table calculation as % of Total.
Step 8 : Select SUM(0) under the marks card .
Step 9 : Change the colour to white.
Step 10 : Decrease the size of the circle to get the Donut Chart.
Format the colours and the size of the chart to your desired choice to get the final Donut.
