For example, due to project requirements, the X axis is a timeline, which is relatively long, while the Y axis value is relatively fixed, while the zoom method provided by dynamicdatadisplay enables simultaneous scaling. I had to study the source code provided by dynamicdatadisplay. It is not difficult to find that the coordinateutilities Source Code provides the method to scale the X

Original article from: Http://blog.csdn.net/bingcaihuang/article/details/5806139 The Rotation Transformation in 3D space is more complex than the Rotation Transformation in 2D space. In addition to the rotation angle, you must specify the rotation axis. If the three coordinate axes X, Y, and Z in the coordinate system are used as the rotation axes, the points are actually rotated only on the plane of the vertical coordinate

In addition to doing some of the usual charts in the work, there will be a lot of strange chart production requirements.Today's content mainly records how to debug the secondary and secondary axes of the excle chart, and how to customize the adjustment axis labelsFirst look at how to do the secondary ordinate, the work of the total two related data but inconsistent units or orders of magnitude inconsistency, this time to combine the two sets of data t

I've seen the Handbook of motion control chips before, including Nova's MCX314 and PCL6045, and know the concept of interpolation.But what exactly is interpolation, in fact, has always been a little puzzled, and then silly to ask some experts, their argument is:Interpolation can be multi-axis output at the same time, fast. And then I don't know what to ask.Based on my previous experience in stepping motor, as well as my experience in testing stepper m

Arduino + XXD ESC +1000kv motor, using PID to adjust the stability, this morning finally adjust the x, Y axis stability. Recall the problem encountered, really is the value of the test out. The PID algorithm is very simple, writes the words does not need 10 minutes to be able to write, but wants to find the value to the p,i,d three parameter The good luck words, does not needless to say, the bad luck adjustment one months not necessarily can stabilize

This article is from: http://ucdchina.com/snap/9797,thank you! In June 8 last year, the Great Apple company released the latest iPhone 4G, which has many hardware upgrades. For gamers, the largest "Three-Axis Gyroscope "! The first time I heard that this "Three-Axis Gyroscope" was a time ago, I occasionally found that Apple players were testing the positioning function of the iPod Touch. For details, see "l

In 3D transformations, Rotation Transformations are often used, and many transformations are centered around any axis. The following describes two methods to rotate around any unit axis. Assume that the angle to be rotated is A, and the axis around it is R. Method 1: (1) build a new foundation Find the coordinate axes S and T in the other two units of l

MATLABOnly used for drawingPlotThe graph output by the function does not necessarily conform to the desired format,It is often necessary to process the number, range, and interval of the subject. Although it is not difficult to operate, it is often used and easy to forget. So here we will describe it: X = (1:50 );Y = sin (X );Plot (X, Y, '-R *');Xlabel ('x name'); % x axis nameYlabel ('y name ');Legend ('xxx'); % line comment. If there are mult

It is true that the WebService is self-contained in flex. the jar package encapsulates axis and should be changed (I have never seen any instructions on MM about the change ), recently, we plan to use the new axis 1.2rc2 to replace the flex built-in Web service, but this is the case. Original server-config.wsdd configuration file is as follows: Getcategorylist and getitemlistbycategoryid return the ar

How to Get axis to find client-config.wsdd Axis supports the use of handlers on the client side and beyond of the WS-FX ProjectsAre implemented using this feature. configuration information for the client is contained with the client-config.wsdd. By default the axis client code looks for this file in two places: 1) first of all

The dot-by-point comparison method of the previous article is obviously unable to draw a straight line with an inclined angle. Because the x-axis and y-axis are never synchronized, that is, like playing billiards, you hit one, I hit one, and if I get into the ball, I'm going to hit another one.That is, if the line is 45 degrees, there is no way to draw it, only the jagged shape.How do I implement x and y si

What is DMP? DMP refers to the MPU-6050 integrated internal processor, the direct output of four yuan, can reduce the workload of peripheral microprocessors, and avoid the cumbersome filtering and data fusion, DMP official Drive library, is based on MSP430, used to drive DMP. Theoretically, it can be ported seamlessly into the STM32F103 series and STM32F4 series. However, if you are unwilling to transplant yourself, you can draw on the four-axis DMP l

When we use the wide-angle lens Ching to shoot the building, or from the top down to shoot the building, there will be a phenomenon called "perspective convergence" to make the lines on the building appear oblique, and finally converge to a point, rather than the building should have horizontal vertical lines. The phenomenon of perspective convergence is shown in the following illustration: Using Photoshop to simulate shift axis to correct building

Developers who go from iphone to Mac will naturally assume that NSView's subview (or controls) have Z-order, but Apple does not guarantee that Subview is displayed in the order in which they are added. There is no Bringsubviewtofront method similar to UIView in NSView.There should be no intersection between Subview. But since I was turning my iphone project into a Mac, I didn't change much like that. The solution was found. is to use the following methods when Addsubview:[self addsubview: Subvie
