Avoid these scenarios by setting Aggregate by to Automatic. Tableau can create a forecast when the forecast aggregation is a finer level of detail than the view's aggregation, but not when it is at a coarser level of detail even when it is finer, the two values are only compatible if there is a strict hierarchy that Tableau can use (for example, quarters can be evenly divided into three months, but months can't be evenly divided into weeks). Other problems arise when the view’s aggregation and the aggregation specified for the forecast (using the Aggregate by field in the Forecast Options dialog box) are not compatible. For example, if the underlying granularity of the sales data is months but you aggregate by weeks, the result may be a significant number of Null values. Date aggregation can trigger a "too many Nulls" scenario when forecasting attempts to extract more data from the measure than is possible. This can lead to the "too much data" or "too little data" errors described below.

For more information, click here.If Tableau is unable to provide a forecast for your view, the problem can often be resolved by changing the Date value in the view (see Change Date Levels).įorecasting errors can result when the aggregation level of the time series (months, weeks, etc.) is either too fine or too coarse for the data to be forecast.

The result is a bar chart in the tooltip that we can customize (color, font, etc.).Įn vous inscrivant, vous confirmez consentir au traitement de vos données personnelles par Salesforce tel que décrit par l'énoncé de confidentialité. In this case, the measure is relative (percentage) and divided by 2 because I used 50 special characters (and not 100). This calculation could be set in the tooltip to create a bar. To do this a method is existing using special characters and formulas. This trick is really great because it allow users to know the distribution for each county. The last trick I used was to show bar charts in tooltips. For instance, it is not because a county chose UMP (right side) that the global trend is right side and vice-versa! Indeed, this was not a map as a function of political party, and it tried to show a different view of French counties. This map was different compared to ones seen in the press. Moreover, I tried to create a map which shows an overview of French counties as a function of the political side. The same method was used to create the map (the difference is that I chose vote quantity instead of percentage). This calculation gives me a percentage used in a bar chart. The first part of the calculation is the percentage for the left side candidate and the second part is the total. The parameters were inserted in calculations to provide a percentage corresponding to the candidate's result. This trick is used to calculate the result for France and for each county.
Users can type a value from 0 to 100, and even give a little part to abstention. Indeed, I used parameters to allow users to simulate the final result as a function of the transfer of votes between candidates. The main trick is about using parameters. This viz was created during the "inter-rounds weeks", and the aim was to simulate the final result: who will be the next president?! I chose to remake an old viz I did 3 years ago about the presidential election. This month, Tableau Public launched Hacker Month to promote out of the ordinary vizzes.
