The overlapping and stacking of echarts’ histogram realizes the display of two bars and the previous difference display.
renderings Main idea Prepare three cylinders (original plan, actual progress, difference) The original plan and actual progress are set to overlap {<!– –> barWidth: 20, // yAxisIndex: 1, z: 1, name: ‘original plan’, type: ‘bar’, stack: ‘ab’, emphasis: {<!– –> // Click on the cylinder and the color of other cylinders will become lighter. disabled: […]
Assignment “Digital Signal Processing” gives a certain set of digital signals. In addition to the target signal, the signal is also mixed with strong noise, but the frequency of the noise and the target signal does not overlap. It is required to use the knowledge learned this semester to analyze the signal. at

Qt desktop whiteboard tool part 2 (implementation method of highlighter and solving the problem of overlapping dark spots caused by transparency)
Previous article: One of the Qt desktop whiteboard tools (solve the problem of uneven curves – Bezier curve) 1. Foreword: I’m quite talkative and may talk a lot of nonsense. In the previous article, I mainly shared about the problem of non-smooth curves solved by the Bessel algorithm. Simply put, we can use the algorithm […]
Heap utilization-Chunk extend Overlapping
Vulnerability Introduction chunk extend Overlapping is a relatively common method of utilization in the heap. The main principle is that we can modify the size of some heap blocks that have been applied for or are in the idle state due to some unexpected situations, resulting in overlapping heap blocks, which is also It caused […]
Threejs–Fourteen, about depth conflict, overlap, and the realization of the effect of loading model progress bar (with complete code)
Deep conflict Two overlapping models, through browser rotation preview, will find that the model will flicker when rotating. In this case, the two models overlap, and the computer cannot tell who is in front and who is behind. This situation can be understood as a deep conflict Z-fighting. function addBox() {<!– –> const geometry = […]
OpenStack (4)–NameSpace realizes overlapping network segments of different projects (tenants)
Openstack isolates the networks of different projects (tenants) through namespaces. The administrator of each project needs to plan and construct the project network, which leads to the reuse of certain network segments between different projects. For example, 192.168.X.X is the management The network segment used by the staff. Last time we created a new instance […]

How to simply use overlap, grid, tab to draw their combined graphics for tables with date and sales or production quantity of an item in the data
This article is suitable for those who are new to learning overlap, grid, tab< /strong>The superficial use of the three combined graphics (ps: If the writing is not good, please ignore it, please do not reprimand) Thinking: overlap component, combined component grid and paging component tab are all composite components, which require more than two […]
