Add a Legend
In SciChart, a chart legend can be created and configured via the LegendModifier:
|
Copy Code | |
|---|---|
// Create a LegendModifier and configure a chart legend ModifierGroup legendModifier = sciChartBuilder.newModifierGroup() .withLegendModifier() .withOrientation(Orientation.HORIZONTAL) .withPosition(Gravity.CENTER_HORIZONTAL | Gravity.BOTTOM, 10) .build() .build(); // Add the LegendModifier to the SciChartSurface surface.getChartModifiers().add(legendModifier); | |
Add a Cursor (Crosshair)
CursorModifier adds a crosshair onto a SciChartSurface. When you put your finger on the screen or otherwise click it, it shows series values in tooltips and chart coordinates at that point point.
| Example Title |
Copy Code |
|---|---|
// Create and configure a CursorModifier ModifierGroup cursorModifier = sciChartBuilder.newModifierGroup() .withCursorModifier().withShowTooltip(true).build() .build(); // Add the CursorModifier to the SciChartSurface surface.getChartModifiers().add(cursorModifier); | |
