# Typography and Scale

## Overview

The Typography and Scale settings allow developers to customize the visual representation of the gauge’s textual elements. By configuring properties such as `ValueFontFamily`, `ScaleLabelsFontFamily`, `ValueFontStyle`, `ScaleLabelsFontStyle`, and `ScaleLabelsFontSize`, as well as the colors for the text (`TextColor`), tick marks (`TickColor`), and scale labels (`LabelColor`), you can ensure that the gauge’s value and scale markers are both aesthetically pleasing and readable.

### Key Points

<table><thead><tr><th width="264">Aspect</th><th>Details</th></tr></thead><tbody><tr><td>Main Value Display</td><td>Controlled by properties such as <code>ValueFontFamily</code> and <code>ValueFontStyle</code>, which determine the font family and style for the gauge’s primary numeric readout.</td></tr><tr><td>Scale Label Styling</td><td><code>ScaleLabelsFontFamily</code>, <code>ScaleLabelsFontStyle</code>, and <code>ScaleLabelsFontSize</code> define the appearance of the scale markers’ labels around the gauge.</td></tr><tr><td>Text and Marker Colors</td><td><code>TextColor</code>, <code>TickColor</code>, and <code>LabelColor</code> allow fine-tuning of the colors for the displayed value, tick marks, and scale labels to ensure legibility.</td></tr><tr><td>Visibility of Scale Elements</td><td>The gauge includes options for showing or hiding textual value (<code>ShowGaugeText</code>) and for rendering scale markers to assist in interpreting the gauge range.</td></tr></tbody></table>

### Best Practices

<table><thead><tr><th width="306">Recommendation</th><th>Description</th></tr></thead><tbody><tr><td>Choose Readable Font Families</td><td>Select font families for both the value display and scale labels that are clear and consistent with your overall UI design.</td></tr><tr><td>Balance Font Styles and Sizes</td><td>Use contrasting styles (e.g., bold for the main value, regular for scale labels) and appropriate sizes to ensure the primary information stands out while maintaining readability for scale markers.</td></tr><tr><td>Ensure Adequate Color Contrast</td><td>Set <code>TextColor</code>, <code>TickColor</code>, and <code>LabelColor</code> to colors that provide sufficient contrast with the gauge background for optimal readability.</td></tr><tr><td>Synchronize with Overall Theme</td><td>Align typography choices with your application’s design language; consider using theme management to set consistent values across multiple controls.</td></tr></tbody></table>

### Common Pitfalls

<table><thead><tr><th width="318">Pitfall</th><th>Explanation</th></tr></thead><tbody><tr><td>Using Inappropriate Font Sizes</td><td>Setting the <code>ScaleLabelsFontSize</code> too small or too large can hinder legibility or overwhelm the gauge; always test at different sizes and resolutions.</td></tr><tr><td>Poor Color Contrast</td><td>Selecting text or tick colors that are too similar to the background can result in a hard-to-read display, particularly under varying lighting conditions.</td></tr><tr><td>Overloading the Gauge with Text</td><td>Enabling too many textual elements or excessively decorative fonts can distract from the gauge’s primary purpose of displaying dynamic data.</td></tr><tr><td>Inconsistent Typography Choices</td><td>Using fonts or styles that clash with the overall application theme can reduce the professional appearance and cohesiveness of your UI.</td></tr></tbody></table>

### Usage Scenarios

<table><thead><tr><th width="282">Scenario</th><th>Implementation Details</th></tr></thead><tbody><tr><td>Standard Dashboard Display</td><td>Use clear, sans-serif fonts for both the main value and scale labels (e.g., "Segoe UI") with contrasting colors to ensure that all numeric data is easily readable at a glance.</td></tr><tr><td>High-Contrast Environments</td><td>Configure bold font styles and high-contrast colors (e.g., white text on a dark background) for environments where ambient lighting may affect readability.</td></tr><tr><td>Detailed Instrument Panels</td><td>Adjust <code>ScaleLabelsFontSize</code> and font styles to ensure that the scale markers are neither too intrusive nor too faint, striking a balance that aids data interpretation.</td></tr></tbody></table>

### Real Life Usage Scenarios

<table><thead><tr><th width="305">Scenario</th><th>Example Description</th></tr></thead><tbody><tr><td>Financial Applications Dashboard</td><td>The gauge displays stock prices or key performance indicators using a bold value display and subtle scale labels, ensuring critical numbers are prominent yet supported by clear tick markers.</td></tr><tr><td>Industrial Control Panels</td><td>In a system monitoring critical parameters (like temperature or pressure), high-contrast, legible typography ensures operators can quickly interpret gauge readings.</td></tr><tr><td>Medical Monitoring Systems</td><td>Gauges in healthcare devices use consistent, readable fonts and scale markers to accurately display vital signs, ensuring reliability even under stressful conditions.</td></tr></tbody></table>

### Troubleshooting Tips

| Issue                                 | Troubleshooting Approach                                                                                                                                                         |
| ------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Text Not Readable                     | Verify that `TextColor`, `TickColor`, and `LabelColor` provide enough contrast with the gauge background; adjust `ScaleLabelsFontSize` and font styles if needed.                |
| Scale Markers Overlapping             | Ensure that the gauge size and the configured `ScaleLabelsFontSize` are proportionate; consider adjusting the control’s dimensions or reducing the font size for better spacing. |
| Inconsistent Typography Across Gauges | Standardize font and color settings through a shared theme or configuration class to maintain consistency across multiple gauge instances.                                       |
| Font Family Not Applying              | Double-check that the specified font family exists on the target system; if not, use a fallback font (e.g., "Segoe UI") to ensure proper rendering.                              |

### Code Examples and Integration Samples

#### Example 1: Basic Typography Setup

```csharp
// Create a new instance of the gauge
SiticoneGaugeDigital gauge = new SiticoneGaugeDigital();

// Set font properties for the main value display
gauge.ValueFontFamily = "Segoe UI";
gauge.ValueFontStyle = FontStyle.Bold;

// Set font properties for the scale labels
gauge.ScaleLabelsFontFamily = "Segoe UI";
gauge.ScaleLabelsFontStyle = FontStyle.Regular;
gauge.ScaleLabelsFontSize = 8f;

// Set colors for the text and scale markers
gauge.TextColor = Color.Black;       // For the main value display
gauge.TickColor = Color.Gray;        // For the tick marks
gauge.LabelColor = Color.DarkGray;   // For the scale labels

// Enable the display of the gauge text
gauge.ShowGaugeText = true;

// Add the gauge control to the form
this.Controls.Add(gauge);
gauge.Location = new Point(15, 15);
gauge.Size = new Size(300, 300);
```

#### Example 2: High-Contrast Typography for Readability

```csharp
// Configure gauge for a high-contrast environment
gauge.ValueFontFamily = "Arial";
gauge.ValueFontStyle = FontStyle.Bold;
gauge.ScaleLabelsFontFamily = "Arial";
gauge.ScaleLabelsFontStyle = FontStyle.Regular;
gauge.ScaleLabelsFontSize = 10f;

// Set contrasting colors for text elements
gauge.TextColor = Color.White;
gauge.TickColor = Color.WhiteSmoke;
gauge.LabelColor = Color.LightGray;

// Optionally, change the gauge background for extra contrast
gauge.GaugeBackColor = Color.Black;

// Force a redraw to immediately reflect changes
gauge.ForceRedraw();
```

#### Example 3: Dynamic Typography Update Based on User Interaction

```csharp
// Subscribe to an event to dynamically update typography (e.g., changing font size on a button click)
buttonIncreaseFont.Click += (sender, e) =>
{
    // Increase the scale label font size
    gauge.ScaleLabelsFontSize += 1;
    gauge.ForceRedraw();
};

buttonDecreaseFont.Click += (sender, e) =>
{
    // Decrease the scale label font size, ensuring it doesn't drop below a minimum size
    gauge.ScaleLabelsFontSize = Math.Max(6, gauge.ScaleLabelsFontSize - 1);
    gauge.ForceRedraw();
};
```
