Xcl-charts powerful dashboard

The dashboard in xcl-charts is one of the most troublesome diagrams I encapsulate. The reason is that people who have used it all know that this type of graph is too special. It is not easy to encapsulate it for most cases.

Fortunately, after a hard work, we finally developed a set of methods that we felt okay.

First, the following results are displayed:

Okay.

This type of chart is encapsulated separately. From the perspective of the overall layout, it can be divided into dashboards of different angles, such as 180,270 and 90,360. From the content perspective, there are two main difficulties: Various loops and various pointers.

You should observe the loop and pointer in the demo to understand the number of classes.

During encapsulation, I divided the rings of different styles into eight categories to plot and process most of the ring styles. Then, you can use the attributes to draw a picture suitable for your own needs.

Because there are too many categories, I will not illustrate how each circular axis is displayed.

As for pointers, as shown in the demo, I am hereDemonstrate several pointers of different styles and how to display multiple pointers in combination. This certainly does not include all of them. It is set through the combination of attributes and the combination with the annular axis.

You can customize various types of pointers.Because the basic calculation and drawing element chart library has been set up and opened up. So you don't have to worry about not drawing a proper pointer.

Pointers are one of the main issues that come back to us. The demo contains various types of graphs. Do I encapsulate each of them in the chart library independently?

Of course, the answer is no. My solution is as follows:

As mentioned earlier,I encapsulated eight types of axis styles. When drawing, you can decide which axes to add and where to display them.

My method is obvious. I give all the decisions to the user, and use the user's own add, and then use the relevant axis attribute settings to draw their own satisfactory results.

How much creativity they have can be drawn in a free combination.

Oh, forget, there is anotherDisplay of text in a dashboard. You often need to customize different texts. For this,My solution is to give the decision to the user.

After you have set the text and the paint brush attribute, you can specify the display position. How can this problem be solved?, My demo has proved.

It is useless to say so much. I will show the code of the example of the mixed graph (including the 270,180, 90 dashboard and the add method for different axes) in the demo above.

The code is messy, but the display function is sufficient.

Well, I don't want to talk about it. If you want to know more about it, go to GitHub or open-source China and check out the code.

Believe me, there is always something you need for this chart library.Hey.
