Today, I will introduce to you why the query panel of big data report is displayed on the left. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.

Whenever customers put forward the need to do drop-down linkage for data filtering, I generally recommend using parameter reports to achieve the following up and down layout effect.

For customers' own JSP pages, when this up-and-down form can not meet the layout requirements, I can only suggest customers to use custom parameter query pages to achieve, that is, write their own pages, want to do, develop their own.

So, can you meet the flexible layout requirements directly through the reporting tools? Here I would like to share a mental process in the process of implementing real requirements:

The query process required by the customer is shown in the following figure. First, select the region above, click the query button, and then list the cities included in the lower left area, and display the corresponding logistics analysis data on the right side of the lower part. Then, each time you click on the city option on the left, the logistics analysis data analysis shown on the right will change.

The dry report tool provides the basic function of refreshing the report according to the parameters, which can directly realize the requirement of parameter query, but directly through the report tool to design and realize the page linkage and page structure? What are the difficulties?

When I finally wrote the evaluation results to my customers, I finally broke the fixed mindset and suddenly realized that this requirement can actually be achieved by moistening the report. Isn't the DBD layout in the report group a function to solve the flexible layout of the page? And can also achieve block linkage!

Now I will use the above example to do a simple example, specifically talk about the process of implementation (of course, there is a small selfishness, that is to strengthen my own consciousness through explanation).

First, do two rpx, one is the condition on the left side of the lower part, the report file is called "Block Linkage 0.rpx", the other is the data report on the right side of the lower part, and the report file is called "Block Linkage .rpx".

We can then use the dashboard panel in the report group for layout.

Create a new report group file (menu "File" / "New report Group"), and add the two reports we created above to the report group, save the report group file to the reportFiles/02 parameter form directory, and the file name is "Block Linkage .rpg".

The third step is to layout the two reports in the Dashboard panel on the right:

Next, create a parameter report with the file name "Block linkage _ arg.rpx".

The editing style of the B1 cell is the drop-down dataset, the dataset used is ds1, and the fields of the display column and data column are the shipper area.

The variable name is set to area

The cell expression is "Northeast".

Finally, publish the report group!

The following is the effect on the page, because we set the default values for the parameters when making the table, the first data loaded is the data corresponding to the northeast region and Dalian.

When you click Changchun on the left, there is no need to click the query button, the data on the right will be partially refreshed.

This is why the query panel of big data report is displayed on the left, and why the query panel of big data report is displayed on the left.
