Click Store. 6 Click OK to accept all the changes and close the dialog box. The next figure shows the dialog box with fields filled in. The customized control is stored in the Linear Gauge folder. 2-31 2 Using Gauges in a Model An alternative to this procedure is to export customized controls to . gms files. To do this, select a folder from the left side of the panel and click Export. You can later access these controls by using the Import button, or share the controls by sharing the . gms files. 2-32 3 Categories of Controls · "Angular Gauges" on page 3-2 · "LEDs" on page 3-5 · "Linear Gauges" on page 3-7 · "Numeric Displays" on page 3-11 · "On Off Gauges" on page 3-14 · "Percent Indicators" on page 3-15 · "Strip Chart" on page 3-18 · "Using Your Own Microsoft® ActiveX Control" on page 3-19 · "Block Parameters for the ActiveX Control Block" on page 3-23 3 Categories of Controls Angular Gauges In this section. . . "Library Overview" on page 3-2 "Customizing Angular Gauges" on page 3-2 Library Overview The Angular Gauges library contains controls that show their input value graphically along an arc of a circle. Blocks in the library differ from each other in their numerical ranges and in their use of needles, numerical labels, text captions, annular components, and tick marks. Customizing Angular Gauges This section describes how to customize angular gauges by making changes that are specific to the Angular Gauges library. For changes that apply to multiple categories of blocks, see these sections: · "Using Multiple Styles Within One Block" on page 2-3 · "Displaying Text on a Block" on page 2-9 · "Modifying the Displayed Range" on page 2-11 · "Modifying Multiple Tick Marks" on page 2-13 The table below lists some common customizations involving the ActiveX Control Properties dialog box that are specific to blocks in the Angular Gauges library. 3-2 Angular Gauges Task Change the shape or size of a needle Description On the Needles panel, set NeedleID to the ID of the needle you want to change (0 if there is exactly one needle). Then use the Style property to choose the shape, and the Length and Width properties to determine the length and thickness. On the Digital panel, set NeedleID to the ID of the needle you want to label and check the Enabled check box. On the Digital panel, first set NeedleID to the ID of the needle whose label you want to change. Then use Decimals to set the number of digits after the decimal point, Color to set the color of the number, and FontID to refer to a previously defined font (on the Fonts panel). On the Digital panel, first set NeedleID to the ID of the needle whose label you want to change. Then use X Position and Y Position to set the fixed position for the label. On the Annulars panel, first set AnnularID to the ID of the annular region you want to change. Use the Radius properties to control the annular region's thickness and radial position. Use the Value properties to control the portion of the scale's range that the annular region includes. This deletes all properties associated with the region, such as its color and thickness. Label a needle by displaying the corresponding number Change the appearance of a needle label Move a needle label Draw an annular region along the scale Change the appearance of an annular region Delete the most recently added annular region 3-3 3 Categories of Controls Combining Multiple Needles in One Display To display multiple needles on a single block, see the table below. To learn how to control multiple needles simultaneously, see "Controlling Multiple Graphical Elements" on page 2-18. Task Add another needle to the display Description On the Needles panel, increase the Needles property. To specify properties of the new needle, set NeedleID to that ID and then set the remaining properties on the dialog box panel accordingly. This deletes all properties associated with the needle, such as its color and shape. Delete the most recently added needle from the display 3-4 LEDs LEDs In this section. . . [. . . ] When using the alphanumeric mode, you can control the display via an M-file S-function that uses the COM support features in MATLAB software. For an example of controlling a gauge using an M-file S-function, see "Updating Multiple Portions of a Pie Chart" on page 2-23. Blocks in the Library The blocks in the Numeric Displays library are · Generic Numeric LED · HH:MM · HH:MM:SS · IRIG Format · Odometer · PlusMinus XX. XXX · VCR Clock 5-10 Numeric Displays Dialog Box The ActiveX Control Properties dialog box governs the appearance and functionality of the control that is embedded in the block. The table below lists the panels of the ActiveX Control Properties dialog box. Panel Background General Library Purpose Configure the background and outline of the block Define the number, appearance, and arrangement of digits on the block Refer to property settings as a named collection The Block Parameters dialog box governs the relationship between the Simulink block and the control embedded in the block.
