Tableau Color indicator from previous day to today.

Tableau Color indicator to compare sales previous day to today.

The calculation uses LOOKUP function to get the rate for previous day.

(It is like Today's value - Previous days value)/Previous days absolute value.

If the above > 0 then "Color1"

Else If the above <0 then "Color2"

IF
(ZN(([Success Rate])) - LOOKUP(ZN(([Success Rate])), -1)) / ABS(LOOKUP(ZN(([Success Rate])), -1))=0 then
"white"
ELSEIF
(ZN(([Success Rate])) - LOOKUP(ZN(([Success Rate])), -1)) / ABS(LOOKUP(ZN(([Success Rate])), -1))>0 then
"green"
ELSEIF
(ZN(([Success Rate])) - LOOKUP(ZN(([Success Rate])), -1)) / ABS(LOOKUP(ZN(([Success Rate])), -1))<0 then
"red"
END

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...
