Create Line Effects in Axure RP: A Simple Guide

Simple Line Effects in Axure: A Step-by-Step Guide

When designing knowledge maps or flowcharts, connecting elements and creating line effects is essential for clarity and visual organization. This guide will walk you through a simple process using Axure to achieve this effect, making your designs more intuitive and efficient.

Step 1: Setting up Global Variables

Start by defining three global variables:

• startX: Stores the x-coordinate of the starting point.
• startY: Stores the y-coordinate of the starting point.
• PI: Represents the mathematical constant pi for trigonometric calculations (simplifies code).

Step 2: Dynamic Panel Structure

Create a simple dynamic panel with a hidden rectangle named "Line" inside.

Important: Select the option "100% width" for the dynamic panel. This ensures the line will automatically adjust to the available width without manual adjustments.

Step 3: Dynamic Panel Interactions

Configure the interactions for your dynamic panel:

• On Load: Set the height of the dynamic panel to [[Window.Height]]. Since the width is already set to 100%, no further width adjustments are needed.

• On Drag Start:

  • Set the variables startX and startY to the mouse's current position.
  • Set the dimensions of the "Line" rectangle to 1x1.
  • Move the "Line" element to the dynamic mouse position.
  • Make the "Line" visible.

• On Drag End:

  • Reset the values of startX and startY.
  • (Optional) Add interaction logic for adding a new line segment here.

• On Drag:

  • Reset the rotation angle.
  • Calculate the dimensions of "Line" using the Pythagorean theorem.
  • Rotate the "Line" element using trigonometric functions to position it correctly based on the mouse movement.

That's it! You have successfully implemented a simple line drawing effect in Axure.
