This video is major to introduce X Y graphs is to read one or more consecutive sets of data in different regitsters, the corresponding data is plotted as dots. It is a curve formed by connecting these points.
Hello, welcome to the touch screen operation video tutorial, we will talk about the XY chart, XY chart is to read a continuous set of data to obtain a number of different results, the corresponding data to draw points, from these points connected to the curve, the following is to talk about the operation method, click on the components - curve, click on the xy chart, open the property page, open the way is divided into periodic and trigger type The default is periodic, the default period of one second, the minimum can be 0.1 seconds, trigger type need to specify the bit or word address to control, we take the periodic type as an example. Using cursors can, to specify a bit address to show or hide the cursor, 1 is to show, 0 is to hide, cursor data area is the xy chart and the cursor crossed by the x point or y point, the data type is 16-bit unsigned, here we specify the address is 100, X is LW100, y is LW101, and then look at the number of data points, the default number of data points is a constant, and is ten, it can be from two to 4096, or you can use variables. We will take eight here as an example. Pause control needs to specify a register, such as LB1, when LB1ON pause refresh, clear control we specify a register LB2, when LB2 is 1, is cleared the current xy value, we look at the channel again, the default is one, can be up to 16, I default is x address and y address is continuous, for example, specify the x address is LW0, y address will become For example, if we specify the x-address as LW0, the y-address will become LW1, the type is 16-bit unsigned, or we can change it to something else, such as a 32-bit unsigned number, the address is changed to LW2 by default, the y-address can also be discontinuous, let's click here to specify it again, here we take the contact address as an example, the type is 16-bit unsigned, tick the draw point mark, we can clearly see the data point. Here is the x-axis and y-axis maximum small value, can be a constant or variable, the following is the channel address, because this side is 8 points, xy each account for an address, a total of 16, LW0 to LW15, X0 is LW0, Y0 is LW1, and so on, now look at the scale, the scale default use 1 channel, can also be set, Y-axis scale is similar, you can also change the background colour, and then determine the establishment of an xy chart, adjust the size, other components have been added, we now simulate a little, you can see the xy chart a second refresh, click on the pause, you can see no longer refresh, we can click on the cursor, you can see the current display of data xy axis and cursor data points, move around to see, you can see the data constantly changing, clear to see Click to clear the xy chart is no more. xy chart of the explanation here is the end, thank you for watching.
