The under ones are not many expansions in Tableau:
Characterize LOD Expression :-
LOD Expression represents Level of Detail Expression, and it is utilized to run complex questions including many aspects at the information obtaining level.

Characterize TreeMap: TreeMap is a perception that sorts out information progressively and shows them as a bunch of settled square shapes. The size and shades of square shapes are separate to the upsides of the information focuses they project. Parent square shapes will be tiled with their kid components.
Heat guide and Treemap:TreeMap Heat MapIt addresses the information progressively and shows them as a bunch of settled square shapes.It addresses the information graphically which utilizes various shadings to address various qualities. It is utilized for contrasting the classes and shadings, size, and it can likewise be utilized for outlining the various leveled information and part to entire connections.

Reality and aspects of the table :
Realities are numeric proportions of information. They are put away indeed tables. Truth tables store that kind of information that will be examined by aspect tables. Truth tables have unfamiliar keys partner with aspect tables. Aspects are engaging properties of information. Those will be put away in the aspects table.

Information displaying is the examination of information protests that are utilized in a business or other setting and furthermore utilized as distinguishing proof of the connections among these information objects. It is the initial step of doing protest situated programming.
Double pivot is utilized to show 2 measures in a solitary diagram. It permits you to analyze 2 measures on the double. Numerous sites like without a doubt utilize this Dual-hub to show the examinations and development rate.Mixed hubVarious measures can partake in a solitary pivot with the goal that every one of the imprints will be displayed in a solitary sheet. We can mix measures by hauling the first measure on one pivot and the second on the current hub.
Retires and sets :
Racks: Every worksheet in Tableau will have retires like sections, columns, marks, channels, pages, from there, the sky is the limit. By putting channels on racks we can construct our own perception structure. We can handle the imprints by including or barring information.
Sets: The sets are utilized to register a condition on which the dataset will be ready. Information will be assembled in light of a condition. Fields which is answerable for gathering are known resources. For instance – understudies having grades of over 70% .
- At whatever point we set a setting channel, Tableau produces a temp table that requirements to invigorate every single time, at whatever point the view is set off.
- In this way, assuming the setting channel is changed in the information base, it needs to recompute the temp table, so the exhibition will be diminished.
- Mark Card in TableauThere is a card to one side of the view where we can drag fields and control mark properties like tone, size, type, shape, detail, name, and tooltip.

2. Bullet chart:A slug diagram is a variation of Bar chart. It is answerable for contrasting the exhibition of one measure and different measures.
3. Gantt diagram:Gantt Chart shows the advancement of significant worth over the period. It comprises of bars alongside the time pivot. It is a venture the board instrument. Here, each bar is a proportion of an assignment in the undertaking system.

- Stacked Bar outline:Stacked Bar Chart, made out of numerous bars stacked on a level plane, one underneath the other. The length of the bar relies upon the worth in the relevant item. A stacked bar graph makes the work simpler, they will assist us with knowing the progressions in all factors introduced, next to each other. We can watch the progressions in their aggregate and figure future qualities.
- Stacked Column Chart :Stacked Column Chart, made out of numerous bars stacked upward, one on another. The length of the bar relies upon the worth in the element. A stacked section diagram is the best one to know the progressions in all factors. This kind of diagram should be checked when the quantity of series is higher than two.
