Charts are greyed out when they don’t logically fit the data presented to them. If that chart is greyed out then clear the chart and draw symbol and close into place, which will put sum(close). Change the close to a dimension so that it uses individual daily stock prices and does not average or sum.ĭrag the stock symbol onto the detail mark. Now you put the stock symbol on the columns and the closing stock price on the row. You can use this data, which I assembled from Yahoo Finance and Stockpup and then loaded into a database.

How to create a box and whisker chartĭownload a source of stock prices and connect that to Tableau. The usual way that online charts provide additional information is by popping up a text box with extra metrics when you hover the mouse over one spot-which you obviously cannot do on paper. That is useful when, for example, you need to print these charts, showing them to someone or using them as part of a non-digital presentation. The box and whisker chart conveys in one glance more information than you’d otherwise get from a bar chart. The box colored grey is the 2nd quartile. The median price is $92.50 because half of the prices range between the lower and upper hinges, which are the 2nd and third quartiles. Over this time period, the price has ranged from $29 to $151.60. The stock on the left is Johnson & Johnson. Box and Whisker Chart Illustratedįor example, if we look at the range of stock prices for three stocks over a certain period of time we get this box and whisker plot: Tableau draws a box around the 2nd and 3th quartile, hence the name box and whisker chart. The hinges are bottom and top of 2nd and 3rd quartiles respectively. Tableau has their own names for these quartiles: hinges and whiskers. Those quartiles are then 1st, 2nd, 3rd, and 4th. Quartiles divide that range of data into four equal ranges. That means the value where 50% of the points are above that value and 50% are below. Median is defined as the point that divides the number of data points in half. Use the right-hand menu to navigate.) Median definition (This article is part of our Tableau Online Guide. It lets you see at a glance the median and the range of data points that lie within each quartile. A box and whisker plot provide more statistical information on a single chart than you would normally be able to fit.
