There are several interaction modes to help you explore and analyze your data. These modes are organized into two toolbar menus:
- Inspect - Tools for exploring and inspecting data (Crosshair, Inspect Points)
- Insert - Tools for creating new elements (Draw Line, Draw Area, Add Callout)
Each mode can be deactivated by selecting "Off" in the Inspect menu or pressing the Esc key.
The Inspect menu contains tools for exploring and analyzing your plot data.
Helps you precisely read compositions at any point in the plot. As you move your cursor over the plot, you'll see:
- Red dashed lines showing the composition values for each component
- A tooltip displaying the exact numerical values
- Press once to lock the current position (useful for taking measurements or screenshots)
- Press again to unlock and continue exploring
- Use the copy button in the tooltip to copy the composition values to your clipboard
Helps you explore and identify specific data points in your plot:
- Hover over any region to highlight the nearest data point
- See the point's title and composition values via dashed guide lines
- Press once to lock the selection on a point
- Press again to unlock the selection
- Use the copy button to copy the point's composition values
- Particularly useful when points are densely packed or when you need precise readings
The Insert menu contains tools for creating new plot elements.
Allows you to create new lines by connecting existing points:
- Hover over points to see their compositions
- Click points in sequence to add them to your line
- Click a point again to remove it from the line
- Hold the mouse button down longer on the last point to finish the line
- The new line will appear in the lines table with default styling
- Lines are automatically drawn with linear interpolation between points
Similar to Draw Line, but creates filled areas instead:
- Works exactly like the Draw Line mode for point selection
- Creates a closed shape that fills the area between selected points
- Hold the mouse button down longer on the last point to complete the area
- The new area will appear in the areas table with default styling
- Useful for marking regions of interest or composition ranges
Allows you to create arrow annotations to label and explain features in your plot:
- Click anywhere on the plot to select where the arrow should point (the target)
- Click on a data point to anchor the arrow to that point
- Click elsewhere to anchor the arrow to specific coordinates
- Move your cursor and click again to place the label
- Labels can be positioned anywhere, including outside the triangle
- Once created, hover over the callout to reveal editing controls:
- Drag the label box to reposition the text
- Drag the blue circle at the arrow tip to move the target
- Double-click the label to edit the text
- Click the trash icon to delete the callout
For complete details on using and styling callouts, see the Callouts documentation.
